ALSTOM IR139‑1 Control Board

Brand: ALSTOM (France)

Model: IR139‑1 (Part No.C0200650)

Device Name: Control board

Product Background

IR139‑1 is Eurocard‑format multi‑serial Modbus communication & control board for ALSTOM ALSPA CE2000 control system, not belonging to GEM80 platform. It is sub‑rack slot‑in module with four independent RS232/RS485 ports supporting Modbus RTU. The CE2000 controller acts as Modbus master via this board to communicate with external slave devices.

OEM production discontinued (EOL). Available stocks are mainly used/refurbished spare parts for legacy power‑plant, metallurgy and railway CE2000‑system maintenance.

Model Breakdown

1. ALSTOM: Brand, France
2. IR139‑1: Hardware model; C0200650 is OEM part code
3. Control board: Product designation, communication control board

Main Functions

1. Multi‑channel Modbus serial communication Four isolated RS232/RS485 serial ports with Modbus RTU protocol. CE2000 controller works as Modbus master, supporting point‑to‑point or multi‑drop bus connection to slave devices for data read‑write exchange.
2. Internal back‑plane bus interaction Exchanges data with CPU processor board over CE2000 back‑plane bus. It forwards master read/write commands and returns acquired slave‑device data back to controller CPU.More products: www.plcva.com
3. Communication link supervision Each serial channel is monitored for communication timeout and message errors. On‑board LED indicators show channel running & fault status for convenient on‑site troubleshooting.
4. Electrically isolated channels Four ports are electrically isolated; failure on one channel will not affect other channels to improve overall communication reliability.
5. Harsh‑industrial‑environment adaptability Designed for heavy‑EMI industrial environment with wide operating temperature range for long‑term continuous operation in power, metallurgy and railway sites.

Note: This board is dedicated for ALSPA CE2000 / CE3000 platform, not compatible with GEM80 system. It cannot operate standalone and must be plugged into CE2000 sub‑rack and work with CPU module.
