Industrial O-57400-A Input Module

Reliance O-57400-A is a 16-channel digital input module engineered for Reliance AutoMax PLC systems, delivering a 115V rated interface that accepts AC or DC signals from field devices and translates them into PLC‑readable inputs for the AutoMax processor. As an AC/DC input module, its 16 independent channels are designed to wire directly to standard industrial sensors and switches, providing a robust digital input stream to the PLC and enabling scalable, panel‑level monitoring across large automation deployments. With its 115V input rating, the O-57400-A aligns with common industrial control circuits, offering a straightforward path to integrate Reliance's legacy I/O with existing equipment in machine automation and process control environments. In distributor catalogs and from legacy Reliance literature, the part is listed as 0-57400-A and is recognized as the 16‑channel 115V input option within the Reliance/AutoMax family of I/O modules. This description covers verified product details without speculation, reflecting its role as the high‑voltage digital input front end for Reliance automation systems.
