Reliance 0-57405-C Analog Input Module

Reliance 0-57405-C Analog Input Module, originally offered under the Reliance Electric brand, is a drive-side analog I/O module that interfaces analog signals to a control system. In legacy automation catalogs it is described as a Drive Analog I/O Module with the 0-57405-C designation, used to feed an automation controller with real‑world analog signals for drive control and monitoring. The part number is consistently referenced in vintage Reliance/Allen‑Bradley catalogs and in refurbish listings as a 0-57405-C device, confirming its role as an analog input interface within older backplane architectures. This module is designed to be deployed in systems that expect Reliance/AB I/O modules and typically requires a compatible backplane or chassis; compatibility with current controllers must be verified, along with ensuring the analog signal type and range align with the controller expectations. In practice, it serves common applications in industrial automation where legacy drives or control panels are maintained, including process control, motor speed regulation, and analog sensing loops that feed into a programmable controller.
