Product Description
Reliance 57C409 (Part No.:0-57409-H) is a 2-channel analog input module of AutoMax / DCS5000 series, manufactured by Reliance Electric (later acquired by Baldor, Rockwell Automation). It features isolated common terminal, multi-range analog signal acquisition, 12-bit signed A/D conversion, built-in programmable filter and over-range detection, with 500μs conversion time per channel. The module converts analog field sensor signals into digital data for the main control rack. Compatible with AutoMax DCS control system, it provides high-precision analog acquisition for drive and process control. It is an obsolete spare part commonly used for legacy production line maintenance and replacement.
