Reliance Electric 57C403 is a 16-channel, 115 VAC high-power output module designed for Allen-Bradley AutoMax NSFP control systems. It provides sixteen outputs that switch 115 VAC loads under the control of an AutoMax processor, enabling centralized control of numerous line-voltage devices from a single controller. Industry references from Rockwell Automation manuals and distributor catalogs identify the 57C403 as a 16-channel high-power output module for 115 VAC applications in legacy Reliance Electric/Baldor Reliance AutoMax/DCS installations.
