Description

The Hitachi MPD110A is a compact modular programmable logic controller(PLC)from Hitachi’s MPD series,designed for machine automation,packaging systems,conveyor control,and small process applications.As part of Hitachi’s industrial automation portfolio(now integrated into Hitachi Industrial Equipment Systems Co.,Ltd.),the MPD110A combines high-speed digital/analog I/O,built-in communication ports,and advanced control functions—including PID loops,high-speed counters(up to 100 kHz),and pulse output for stepper/servo positioning—in a space-efficient DIN-rail package.

The base unit features integrated RS-232 and RS-485 serial interfaces,supporting Modbus RTU,Hitachi’s native protocol,and optional CC-Link or Ethernet/IP via expansion modules.With a scan time as low as 0.3µs per instruction,the MPD110A delivers real-time responsiveness for demanding motion and timing tasks.It is programmed using Hitachi’s ProCon software or Omron CX-Designer(due to historical platform alignment),making it accessible to engineers familiar with Japanese PLC ecosystems.

 

Application Scenarios

At an automotive parts stamping facility in Thailand,a Hitachi MPD110A controls a multi-axis transfer press.The PLC reads encoder feedback via high-speed counter inputs,executes position-synchronized cam profiles,and triggers hydraulic actuators with microsecond precision.Communication over Modbus RTU(RS-485)sends cycle counts and fault codes to a central SCADA system.Despite operating in a high-vibration environment near 1,000-ton presses,the MPD110A has run continuously for over 5 years—thanks to its conformal-coated PCB and robust terminal blocks.When a new safety relay was added,engineers expanded the system with a digital input module(MPD-16ND)in under an hour,showcasing the platform’s modularity.

Technical Principles and Innovative Values

Innovation Point 1:Integrated Motion+Logic

Eliminates need for separate motion controllers—ideal for indexing tables,label applicators,and pick-and-place robots.

Innovation Point 2:Dual Serial Flexibility

Simultaneous programming(RS-232)and SCADA telemetry(RS-485)without add-on modules.

Innovation Point 3:OEM-Friendly Design

Low cost,compact footprint,and wide voltage input make it popular among machine builders embedding control into custom equipment.

Innovation Point 4:Cross-Platform Programming

Compatibility with Omron CX-Designer reduces training burden in multi-vendor plants.

Application Cases and Industry Value

Beverage Bottling Line(Indonesia):Uses MPD110A to synchronize capping,filling,and labeling stations—achieving 24,000 bottles/hour with<0.1%reject rate.

Pharmaceutical Blister Packing(Italy):Controls temperature sealing via PID loop and verifies seal integrity with vision system over Modbus TCP.

Legacy CNC Retrofit(USA):Replaced obsolete relay logic with MPD110A+analog I/O to modernize feed control on a 1980s milling machine.
