ABB 200RA31001A DCS Controller Module for Distributed Control

The 200RA31001A functions as a dedicated controller node within ABB distributed systems. This module executes regulatory loops and sequential logic for process applications. You can rely on it for continuous manufacturing or batch processing tasks.

Key Technical Parameters

The table below lists all essential technical specifications for this controller module.

Physical Characteristics and Installation

This controller module weighs approximately 0.65 kg for stable chassis mounting. Its dimensions measure 180 mm x 130 mm x 50 mm for standard rack fit. First, slide the 200RA31001A into a dedicated DCS rack slot. Then, secure the module using the front panel screws. Finally, connect your network cables to the communication ports. LED indicators on the front show power, run, and fault status.

Processing Power and Memory Architecture

The 200RA31001A integrates a 32-bit RISC processor for fast execution. Program memory uses 512 KB of flash for non-volatile storage. Data memory provides 128 KB of RAM for real-time variables. A supercapacitor maintains this RAM for 72 hours without external power. Consequently, your process data survives short power interruptions.

Control Capabilities and Communication Options

This DCS controller handles up to 16 PID loops for process regulation. The scan cycle runs at 10 ms for responsive control actions. Three communication ports provide flexible network integration. Two RS-485 ports connect to field devices and local I/O. One Ethernet port links the module to the plant network.
