Reliance Electric 57406-F Drive Controller Module

The Reliance Electric AutoMax 57406-F Drive Controller Module is the rack-mount drive controller at the heart of Reliance's AutoMax distributed power system, serving as the primary control module in a four-card drive regulator group (57401, 57405, 57406, 57408). It lists alternate P/N 57C406, is OEM Reliance Electric, and belongs to the AutoMax PLC family as a Drive Regulator Group Module with three front connectors, one fault-code LED, and a reset switch, and it connects to the rack backplane via rear edge connectors. This pre-owned, cleaned and tested unit is designed to operate alongside its sibling modules within an AutoMax rack to manage drive regulation in industrial automation setups. The 57406-F variant aligns with the same family and usage as other 5740x drive controller modules, which historically support Reliance AutoMax drive regulator configurations.
