Industrial 45C305A Programmable Logic Controller Processor

Reliance Electric AutoMate 30 Processor Card, model 45C305A, is the central processing unit for older Reliance AutoMate 30 PLC systems. Designed as a processor module mounted on an I/O rack, it executes the control logic that governs connected I/O modules and field devices, forming the core of the automation loop in legacy Reliance automations. In Enhanced AutoMate 30 configurations, this processor can be paired with a network option such as the R-NET network processor (for example, the 45C202) to enable networked control within a Reliance Automate network. The 45C305A is cataloged as a processor board in the 45C30x family, with common references including 45C305A and 45C305A variants used across Automate 30 installations.
