The Reliance Electric 45C200 manages all input and output scanning tasks for AutoMate control systems. This dedicated processor offloads I/O handling from the main CPU entirely. Consequently, you achieve faster overall scan times and more responsive logic execution.

Hardware Architecture & Component Layout
The 45C200 features a dedicated 8-bit microcontroller for I/O scanning tasks. This module contains no onboard battery or energy storage devices. Instead, it draws all operating power directly from the backplane supply. The board includes 32K of EPROM for permanent firmware storage. Consequently, you never need to update or reprogram this module in the field.
Functional Capabilities & System Integration
This processor automatically discovers all connected I/O modules during power-up. The 45C200 then continuously scans each input and updates the output tables. It communicates this fresh data to the main CPU through the backplane bus. For robust power protection upstream in your automation panel, consider a device like the RMS-TSG-TZ-C Static Trip unit from Siemens (see Alibaba link). That trip unit complements the 45C200 by ensuring stable power for all I/O operations.
Status Indicators & Diagnostic Features
The 45C200 provides three LED indicators on its front panel. A green POWER LED confirms proper backplane voltage availability. A yellow ACTIVE LED blinks during normal I/O scanning operations. A red FAULT LED illuminates when the module detects a communication error. Therefore, you can verify module health with a single glance at the rack.
Installation & Compatibility Notes
Mount the 45C200 into any slot of an AutoMate 15, 20, 30, or 40 rack. This processor requires no configuration jumpers or DIP switch settings. The Reliance Electric 45C200 works alongside the main CPU module 45C410B or 45C203. For maximum system performance, always place the 45C200 in a slot adjacent to the main processor.
