Industrial 61C22 Automation Local IO Head Module

Reliance Electric AutoMate 61C22 Local I/O Head is a compact expansion module that serves as the local I/O interface for Reliance AutoMate automation systems, bridging the AutoMate CPU to field devices and enabling distributed input and output across the shop floor. The 61C22 variant is designed to operate from a 120 VAC power supply and is part of the AutoMate Local I/O Head family, alongside the 61C23 model and catalog references to 61C22A, with documentation found in AutoMate manuals and distributor listings. Used to bring local digital I/O to the AutoMate CPU and to work with AutoMate I/O rails and compatible modules, this head reduces wiring complexity by handling signals locally rather than routing every channel to the central controller, which can simplify installation and maintenance in distributed automation architectures. Although a legacy product, the 61C22 Local I/O Head remains listed by current suppliers and repair providers, indicating ongoing availability of manuals, replacement units, and compatible hardware within the AutoMate ecosystem.
