Industrial 86429-75RA Analog Rail Module Card

Industrial 86429-75RA Analog Rail Module Card, commonly listed as Reliance 61C365, is a four-channel analog output rail module for Reliance AutoMate DCS 5000 / AutoMax systems. It provides four independent 4-20 mA analog outputs to drive external process equipment or actuators via the AutoMate I/O rail, enabling precise current-based control across multiple channels. The 61C365 family is paired in literature with a 61C366 variant that delivers four 0-10 V outputs, and both are documented as part of the same analog rail module family (61C365/61C366). Widely cataloged under the 61C365/86429-75RA identifiers by distributors, this module is designed to integrate into legacy Reliance AutoMate installations and enables scalable analog output for distributed control tasks. Typical applications include process control and instrumentation interfaces within automation systems that rely on current-loop signals, where four independent channels can drive valves, actuators, or analog sensors via the AutoMate rail. The card represents one of the core analog I/O options in Reliance Electric’s Automate era, providing a compact, multi-channel solution for expanding analog output capacity in older automation architectures.
