TCM 4355X Product Overview

The GE TCM 4355X is a core module developed by GE specifically for complex industrial control scenarios.It’s part of its industrial automation control series.Within the automation system,it acts like a”precision dispatcher,”connecting to field sensors and instruments,actuators,and inverters,converting collected signals into precise control commands to ensure optimal equipment operation.

Whether it’s auxiliary control of generator sets in the power industry,dual temperature and pressure regulation of reactors in chemical plants,or collaborative welding robots in automotive manufacturing,the TCM 4355X can handle it with ease.For example,a chemical reactor needs to simultaneously control the temperature at 180°C±0.5°C and the pressure at 2.5 MPa±0.02 MPa.It uses 12 analog inputs to collect temperature and pressure signals and 8 analog outputs to regulate heating pipes and control valves.This achieves an accuracy of±0.05%,making it more accurate than standard modules.Furthermore,it supports dual power supply,allowing the backup power source to be switched in the event of a power outage,ensuring data loss and uninterrupted control.For upgrades to existing plants,existing modules can be directly replaced without modifying existing wiring,saving significant renovation costs.

Main Features and Advantages

Ultra-high-precision control,zero deviation in production parameters:Anyone in the industry knows that even the slightest deviation in a parameter can ruin an entire batch of products.The TCM 4355X offers analog regulation accuracy of±0.05%and 16-bit resolution.For example,when controlling the pulling speed of a thin film production line,a set speed of 5 m/min can maintain a stable actual speed of 5±0.0025 m/min,double the±0.1%accuracy of competing modules.It also features a fast sampling rate,with analog channels sampling 2000 times per second.Any fluctuation in device parameters is immediately adjusted,preventing further deviations.This results in exceptionally consistent products and reduces the defective rate by over 40%.

Dual power supply and strong noise immunity ensure it withstands harsh environments:Industrial sites are complex,with some workshops being cold and humid,others plagued by electromagnetic interference(EMI)from motor inverters.Ordinary modules struggle to withstand these conditions.However,the TCM 4355X can withstand temperatures as low as-40°C,allowing it to operate normally in outdoor control cabinets during northern winters.It also maintains stable operation in metallurgical workshops at temperatures as high as 70°C.It also supports dual power supply:24V DC and 110-240V AC.If one power supply is disconnected,the other automatically switches to the other,preventing control interruptions due to power supply issues.The internal circuitry features three layers of anti-interference shielding,effectively shielding it from high-frequency interference from inverters.Control accuracy remains unchanged in the high-interference environment of automotive welding workshops.Multi-protocol compatibility eliminates the need for”complementary components”:Factories are rife with equipment from various brands,including GE,Siemens,and Schneider.If the modules are incompatible,searching for protocol converters can take days.The TCM 4355X supports Modbus TCP,Profinet,and the GE proprietary bus.Whether it’s a new Profinet sensor or an older RS485 inverter,simply plug it in and it’s connected,eliminating the need for a separate gateway.For example,a Siemens S7-1500 PLC in the workshop can use Profinet to transmit data to the TCM 4355X in real time.Electricians can connect the cables and adjust the parameters in just half a day,saving significant effort.

Flexible expansion allows for effortless capacity upgrades:When a factory expands,the existing module channels may be insufficient,and replacing them with larger modules is both costly and disruptive.The TCM 4355X supports expansion modules.If digital inputs are insufficient,add the GE TCM-EX-DI24(24-channel digital input expansion card),or the TCM-EX-AO8(8-channel analog output expansion card).No need to replace the main module;simply mount it on the DIN rail,connect the cables,and activate it in the software.For example,if you originally controlled 8 devices and expanded to 15,adding two expansion cards would allow you to complete the process in a single day,without stopping the production line or interrupting production.

The GE TCM 4355X stands out as a high-performance industrial control module,engineered to deliver exceptional precision and reliability in the most demanding industrial environments.Its 32-bit dual-core industrial CPU(1GHz)and 16-bit high-resolution analog I/O enable ultra-accurate regulation of critical parameters,such as temperature,pressure,and speed—essential for industries like chemical processing and power generation where deviation minutes can impact product quality or safety.

Featuring dual power options(24V DC/110-240V AC)and a wide operating temperature range(-40°C to+70°C),it adapts seamlessly to diverse site conditions,from freezing outdoor power substations to high-temperature metallurgical workshops.Its robust EMI shielding(compliant with EN 61000-6-2)ensures stable operation even amid heavy electromagnetic interference from motors and frequency converters.

With multi-protocol support(Modbus TCP,Profinet,GE proprietary bus),the The TCM 4355X integrates effortlessly with both GE’s automation ecosystem and third-party devices,eliminating compatibility bottlenecks during system upgrades.Flexible expansion via add-on I/O cards further enhances its scalability,making it a cost-effective choice for factories looking to scale production without full hardware overhauls.

Application Areas

The TCM 4355X is the”core of stable control”in substation auxiliary systems in the power industry.Substations control equipment such as fans,pumps,and heaters,while also monitoring indoor temperature,humidity,and cable temperature.The TCM 4355X uses 24 digital inputs to acquire device status,12 analog inputs to monitor temperature,humidity,and current,16 digital outputs to control device start and stop,and 8 analog outputs to adjust fan speed and heater power.It can withstand winter temperatures as low as-40°C and resist strong electromagnetic interference within substations,ensuring stable operation and reducing three to four unplanned outages annually,ensuring secure power supply to substations.In the chemical industry’s polymerization reaction workshops,the TCM 4355X is a”precise steward.”Polymerization reactions place extremely high demands on temperature,pressure,and stirring speed.The TCM 4355X collects the reactor’s temperature(4-20mA signal)and pressure signals and,through analog output,precisely adjusts the heating oil valve opening and stirring motor speed.The temperature is controlled at 85±0.04°C and the pressure at 1.8±0.01MPa,achieving an accuracy 10 times higher than manual control.Furthermore,it features a fault-interlocking function.If the temperature exceeds the upper limit,heating is immediately shut off and cooling is initiated,preventing runaway reactions.This can save hundreds of thousands of yuan in raw material waste and equipment maintenance costs annually.

In automotive parts die-casting workshops,the TCM 4355X is a”high-efficiency commander.”Die-casting machines require control of injection speed,mold temperature,and hold time.The TCM 4355X uses analog inputs to acquire signals from the injection speed sensor,digital outputs to control the mold heater,and analog outputs to adjust the injection cylinder pressure.This maintains a stable injection speed of 3 m/s±0.01 m/s and mold temperature of 280±1°C,increasing the casting yield from 92%to 99%.It also communicates with the shop’s MES system,automatically uploading production data for easy traceability and improving management efficiency by 25%.

Selection Guide/Purchasing Recommendations

When choosing a TCM 4355X,first consider the site power supply.If the shop only has 24V DC,choose the DC version.If 110-240V AC is available,the AC version is more convenient and eliminates the need for a separate power supply module.Next,consider the I/O channel requirements.It has 24 digital inputs,12 analog inputs,16 digital outputs,and 8 analog outputs.If the number of channels is insufficient,remember to use a genuine GE expansion card;avoid third-party expansion cards,as compatibility is not guaranteed.

Also,consider the environment.If used outdoors,in dusty areas,or in areas subject to splashing water,the TCM 4355X must be housed in an IP67 protective enclosure to prevent dust and water from entering the module and damaging it.If used in a high-interference environment(such as a substation or welding workshop),additional anti-interference equipment is not necessary;the module’s built-in shielding is sufficient.When purchasing,be sure to source from a GE authorized supplier,such as Shenzhen Changxin[www.cnplcdcs.com].Avoid refurbished products.Refurbished CPUs and memory may be outdated,resulting in inaccurate control accuracy and a high risk of production accidents.Don’t skimp on cheap.

Customer Case Study/Successful Application Analysis

The previous control module in the cold rolling mill of a large steel plant had poor interference immunity.Electromagnetic interference from the mill’s operation constantly caused the module to control inaccurately,resulting in large deviations in steel plate thickness.This resulted in the scrapping of dozens of tons of steel plate daily,a significant loss.Later,we switched to the TCM 4355X module,which has strong anti-interference capabilities.Regardless of the mill’s operating conditions,the module’s control accuracy remains unchanged.

The TCM 4355X collects pressure and speed signals from the mill and uses analog outputs to precisely adjust the roll gap.This reduced plate thickness deviation from±0.1mm to±0.02mm,and the scrap rate from 5%to 0.5%,saving over 200,000 yuan in steel waste per month.Furthermore,it supports dual power supply.In the event of a power outage in the workshop,the backup power source immediately switches over,ensuring control is maintained and the equipment does not need to be restarted,ensuring extremely stable production.The plant manager commented,”This module was the right choice.It not only saves money but also makes production much smoother!”
