1C31238H01 high-performance communication interface module

1C31238H01 is a high-performance communication interface module developed by Westinghouse (now integrated into Emerson Automation Solutions) for its Ovation Distributed Control System (DCS). It acts as a critical bridge for data interaction between the Ovation DCS and external devices/systems, enabling stable and efficient transmission of control signals and process data in harsh industrial environments. Below is its detailed information:

1. Core Technical Specifications

Parameter Category	Specific Details
Module Type	Industrial communication interface module, focusing on bidirectional data exchange between Ovation DCS and external equipment (e.g., PLCs, remote I/O stations, third-party control systems).
Supported Protocols	- Primary protocols: Modbus RTU/TCP (for connecting most industrial PLCs, instruments, and SCADA systems) and Ethernet/IP (for seamless integration with Rockwell Automation devices).- Optional support: Ovation proprietary backplane protocol, ensuring compatibility with other Ovation modules (e.g., I/O modules, controllers).
Communication Ports	- 2 Ethernet ports (RJ45 interface, 10/100Mbps adaptive): For TCP/IP-based high-speed data transmission (e.g., Modbus TCP, Ethernet/IP).- 1 RS485 serial port (terminal block interface): For Modbus RTU communication, supporting half-duplex data exchange with serial devices (e.g., legacy PLCs, field meters).- 1 diagnostic port (RS232, DB9 interface): For local configuration and fault troubleshooting.
Power Supply	24V DC ±10% (power consumption ≤8W), fully compatible with Ovation DCS rack power modules (e.g., 1C31234G01), adapting to voltage fluctuations in industrial power grids.
