Industrial 57416-N Remote I Communications Module

The Reliance Electric AutoMax Remote I/O Communications Module, model 57416-N, serves as the backbone of the AutoMax remote I/O network, acting as the essential bridge between the processor master rack and distributed I/O racks in a DCS. This module provides the hardware to facilitate communication across the AutoMax system and is typically mounted in a backplane where it plugs into a female card slot on the remote rack. Power handling is rated around 2.5 A at 5 VDC, supporting the backplane current load for remote I/O traffic. An onboard RS-232C port allows local testing and diagnostics via a serial device, and the unit includes LED indicators such as an OK status light and a 7-segment display to show fault codes for quick troubleshooting. In practice, the 57416-N connects the AutoMax processor module to remote I/O modules, enabling command, status, and data exchange essential for distributed control in industrial environments. Some listings also catalog the same device under alternate designations such as 0-57416-N, but the core function remains remote I/O communications within the AutoMax family. This module is used in automation setups where Reliance Electric AutoMax PLCs control distributed I/O networks, providing the necessary interface to manage remote points from a central processor.
