Industrial 45C381A High Density Solid State Relay Module

Reliance Electric Automate 45C381A is a high-density register output module for Reliance Automate DCS 5000 controllers, providing solid‑state relay outputs to drive loads from the control system. The part is also listed as 45C381-A and is described in automation catalogs as a register output card within the 45C380 family, commonly cited as a 30-output module in the DCS 5000 lineage. In the 45C380-series, register I/O cards feature 16-bit data, on-board power, electrical isolation to logic, and TTL-to-24 VDC logic levels to ensure reliable interfacing to host controllers. This module is designed for expansion of a Reliance Automate control system’s output capacity, enabling multiple controlled loads to be driven from a single chassis.
