Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 57C493 is an Allen-Bradley AutoMax® power supply module used in the AutoMax or DCS 5000 rack systems. It provides the DC power rails required by control modules in a modular backplane-based control rack, converting 115 VAC input to multiple regulated DC outputs. The module supports 6-, 10-, or 16-slot AutoMax/DCS racks and delivers continuous power to downstream control modules. It is typically applied in industrial process control and DCS environments requiring centralized rack power distribution.
