Description
Core Product Summary
The Sigmatek DCP 161 (Article Number: 05-004-161) is a processor control module designed for use within Sigmatek DIAS industrial automation systems. Serving as a central processing unit, the module executes control programs and manages communication across the automation architecture.
Powered by an Intel 386EX processor core, the DCP 161 features onboard program and data storage memory along with a real-time clock and battery data preservation. The unit integrates standard communication interfaces—including CAN bus and serial ports—and includes a 2-digit 7-segment status display with diagnostic LEDs for runtime monitoring and configuration. Because it lacks an internal power supply, the processor module requires an external Sigmatek DPS power supply module.

Detailed Product Overview
The Sigmatek DCP 161 processor module acts as the computational core for legacy Sigmatek DIAS modular control setups. It executes user application logic, coordinates data exchange between connected input/output modules, and interfaces with external supervisory systems or engineering terminals via built-in serial and CAN communication ports.
The module features a robust architecture intended for industrial switchboard cabinets. System status, configuration parameters, and error codes are directly reported via an integrated 2-digit decimal 7-segment display and diagnostic LED layout. Maintenance of volatile application data during power cycles is supported by an onboard lithium battery backup.
