SIGMATEK DCP161 DIAS CPU Processor Module

SIGMATEK DCP161 is a CPU processor module for SIGMATEK DIAS automation control system, powered by Intel 386EX real‑time processor. It runs IEC‑61131‑3 control programs, handles logic computation and I/O data exchange, and relies on DPS power module for power supply, serving as core control unit for machinery automation equipment.

This module is equipped with flash and SRAM memory, and uses built‑in lithium backup battery to retain data after power‑off. It supports up to 16 peripheral I/O modules, and adopts rack‑mount installation inside control cabinet. It is widely used as replacement spare‑part for on‑site troubleshooting, equipment maintenance and legacy machine‑control‑system retrofit projects.
