Reliance 57402-C 115V AC DC Low Output Module

Reliance 57402-C 115V AC/DC Low Output Module is a legacy digital I/O module designed for Reliance Electric/Reliance PLC systems, including AutoMax-era controllers. This low-output module provides circuitry to switch line-voltage loads at 115 volts AC or DC, making it suitable for control tasks within industrial automation where a compact, voltage-compatible output interface is required. The 57402-C is widely listed by distributors as a 115V AC/DC Low Output Module, confirming its voltage rating and role as a digital output device in older AB/Reliance control architectures. When integrating or sourcing spares for equipment that used the AutoMax/RelIance control family, ensure the target controller supports this catalog number and that the physical form factor of the I/O rack aligns with the module in question. In practice, this module would be used to drive actuators or signaling devices that operate at or are compatible with 115V loads, within legacy automation installations where precise backplane compatibility and cataloging are preserved.
