Industrial AS-B814-001 AC Relay Output Module

The AS-B814-001 is an eight-channel AC relay output module for Schneider Electric’s Modicon 800-series PLCs, providing eight 115 VAC normally open relay outputs that let the CPU switch AC loads from the I/O backplane. Each channel functions as a separate NO relay, enabling direct control of devices such as solenoids, contactors, or lighting circuits from the Modicon controller. This module is designed for use in 800-series systems and mates with the standard Modicon backplane interface to distribute output signals to external loads. Key identifiers include the part number AS-B814-001 (alternative reference ASB814001) and 115 VAC NO relay outputs. In distributor catalogs, the AS-B814-001 is described as an eight-point relay output module and is listed as discontinued by Schneider Electric in some listings, indicating it is legacy hardware. Typical applications include industrial automation lines, machine control panels, and process equipment where multiple AC-relayed outputs are required from a single Modicon rack, offering isolated relay switching directly from the PLC without additional interface modules.
