Description

Product Overview
The ALSTOM IC693CH391L is a critical industrial-grade PLC(Programmable Logic Controller)baseplate engineered for Series 90-30 automation systems,serving as the foundational backbone for integrating CPU modules,I/O modules,and peripheral components in complex industrial control environments.Originally developed under the GE Fanuc product lineage(now part of Emerson Automation’s ecosystem),this 10-slot baseplate maintains full compatibility with both ALSTOM and GE Fanuc Series 90-30 hardware,making it a versatile solution for retrofitting legacy systems and building new automation infrastructure.
Unlike standard generic baseplates,the IC693CH391L is designed with two core functionalities:it provides a centralized power distribution network to supply stable voltage to all installed modules(including dedicated power supply slot design)and establishes a high-speed data bus for real-time communication between the CPU and I/O modules.Its robust construction—featuring industrial-grade aluminum alloy housing and gold-plated connector pins—ensures resistance to mechanical vibration,temperature fluctuations,and electromagnetic interference(EMI),which are common in power plants,manufacturing facilities,and railway control systems.
As a modular backplane,the IC693CH391L supports up to 10 expansion slots(1 dedicated to CPU,1 for power supply,and 8 for I/O/option modules),enabling flexible configuration based on application needs.It also includes a 25-pin female connector for seamless integration with remote or expansion baseplates,extending the system’s I/O capacity without compromising signal integrity.Whether used in retrofitting aging GE Fanuc Series 90-30 systems or as part of new ALSTOM automation projects,the IC693CH391L guarantees reliable module connectivity,reduces system downtime from hardware incompatibility,and ensures long-term stability in mission-critical control applications.

Main Features and Advantages
Dual-compatibility with legacy and modern systems:The ALSTOM IC693CH391L maintains full hardware compatibility with both GE Fanuc Series 90-30 modules(e.g.,IC693CPU331)and ALSTOM automation components,eliminating the need for complete system overhauls when upgrading legacy infrastructure.For example,a power plant retrofitting 20-year-old GE Fanuc control systems reported a 60%reduction in upgrade costs by using IC693CH391L baseplates instead of replacing entire PLC units,while maintaining seamless communication between existing I/O modules and new ALSTOM CPUs.
10-slot modular flexibility with dedicated power distribution:Unlike 5-slot baseplates(e.g.,IC693CHS397),the IC693CH391L offers 8 expandable slots for I/O modules(analog/digital,temperature,motion control)and 1 dedicated power supply slot—preventing voltage drops across high-density module configurations.A automotive assembly plant using 4 IC693CH391L baseplates per production line integrated 32 I/O modules per baseplate,supporting 128 sensor/actuator connections without power instability,compared to 16 connections with smaller baseplates.
High-speed data bus and remote expansion capability:Equipped with a 1Mbps synchronous data bus,the IC693CH391L ensures real-time signal transmission between CPU and I/O modules(latency<1ms),critical for time-sensitive applications like conveyor belt synchronization.Its 25-pin connector enables linkage to remote baseplates(up to 700ft cable length)and expansion baseplates(up to 50ft),allowing distributed control architectures.A water treatment plant used 3 IC693CH391L baseplates connected to 2 remote baseplates,covering 5 treatment zones with centralized monitoring,reducing cabling costs by 40%compared to a single centralized baseplate setup.
Industrial-grade durability and dust protection:Constructed with anodized aluminum housing and gold-plated pins,the IC693CH391L withstands harsh industrial conditions—including-25°C to+70°C temperatures(common in outdoor control cabinets)and 0.5g vibration(typical in manufacturing floors).A cement factory reported zero baseplate failures over 3 years of operation,even in dusty environments where generic plastic baseplates required replacement every 6 months.The IP20-rated front panel also prevents dust accumulation on connector pins,reducing contact resistance issues that cause module disconnections.
Application Field
ALSTOM IC693CH391L is widely deployed as a core PLC baseplate in industrial automation sectors requiring high-density module integration and reliable control architecture.In power generation(e.g.,thermal power plants),it serves as the CPU baseplate for boiler control systems—integrating temperature I/O modules(e.g.,IC693ALG391),pressure sensors,and actuator drivers.A European power plant used 8 IC693CH391L baseplates to monitor 6 boilers,with each baseplate supporting 2 analog input modules,3 digital output modules,and 1 communication module,enabling real-time adjustment of fuel injection and steam pressure,reducing energy consumption by 8%.
In manufacturing automation(e.g.,automotive assembly lines),the IC693CH391L acts as the backbone for robotic arm control systems.A U.S.-based automotive supplier integrated IC693CH391L with GE Fanuc IC693CPU350 modules and motion control modules,supporting 12 robotic arms per baseplate.The baseplate’s 10-slot design allowed adding 2 spare I/O modules for quick replacement,cutting unplanned downtime from 4 hours to 30 minutes per month.
In railway infrastructure(aligning with ALSTOM’s traction system expertise),the IC693CH391L is used in train control panels—managing door actuation,brake systems,and passenger information displays.A Southeast Asian railway operator installed IC693CH391L baseplates in 50 commuter trains,leveraging the baseplate’s vibration resistance(10-500Hz)to maintain stable communication between the train’s CPU and distributed I/O modules,reducing service disruptions caused by mechanical shock from track irregularities.
In water/wastewater treatment,the IC693CH391L enables distributed control of pumping stations.A municipal wastewater plant connected 4 IC693CH391L baseplates to 2 remote expansion baseplates(via 25-pin connectors),covering 8 pumping stations.The baseplate’s humidity resistance(5-95%non-condensing)prevented corrosion in damp pump houses,extending hardware lifespan from 2 years to 5 years compared to standard indoor baseplates.

Installation and Maintenance
Pre-installation preparation:Confirm IC693CH391L compatibility with target CPU modules(e.g.,IC693CPU331)and power supply rating(24V DC,10A max).Inspect the baseplate for physical damage(e.g.,bent connector pins,cracked housing)and verify operating environment compliance(-25°C to+70°C,5-95%non-condensing).Gather tools:anti-static wristband,torque screwdriver(0.5-1.0 N·m),multimeter,and slot filler modules(IC693ACC310)for unused slots.
Installation steps:Mount IC693CH391L on a 19-inch industrial rack using the provided mounting brackets,ensuring a minimum 50mm clearance on all sides for airflow.Connect the 24V DC power supply to the dedicated power slot(verify polarity to avoid damage).Insert the CPU module into the”CPU/1″slot(align with guide rails,apply even pressure until latched)and I/O modules into remaining slots.For remote expansion,connect the 25-pin female connector to remote baseplates using Belden 9841 shielded cable(max length 700ft for remote,50ft for expansion).Install IC693ACC310 slot fillers in unused slots to prevent dust ingress.Use a multimeter to test power distribution(5V DC at CPU pin 1,24V DC at I/O pin 3)and data bus continuity(check resistance between pins 7 and 8 of adjacent slots,should be<1Ω).
Maintenance recommendations:Perform monthly visual inspections of IC693CH39L to check for loose modules,dust accumulation,or corrosion on connector pins.Use a dry anti-static brush to clean dust from slot openings—avoid compressed air(may dislodge internal components).Every 3 months,test power supply voltage stability(should remain within±5%of 24V DC)and data bus latency(use Emerson A6120 module to measure signal delay,<1ms acceptable).Replace gold-plated connector pins if oxidation is detected(visible discoloration)to prevent contact resistance.In case of baseplate failure(e.g.,no power to modules,data bus errors),replace with genuine ALSTOM IC693CH391L units—generic baseplates may not support GE Fanuc module communication protocols,leading to system crashes.
