Schneider Electric AS-B872-200 USNT Contactor

Schneider Electric AS-B872-200 USNT is a Modicon 800-series analog output module that provides four voltage-output channels for PLC-driven analog control. Designed to fit in Schneider's backplane-based Modicon systems, this four-point module (often cataloged under BMXAMO0410) accepts digital control data from the PLC and converts it into independent analog voltage signals that drive external devices such as actuators, valve positioners, or other voltage-controlled loads. The USNT designation identifies a specific variant of the AS-B872-200 family, and it is intended for use in compatible Schneider Electric chassis with appropriate backplane wiring. Each channel operates as an individual voltage output, enabling four concurrent analog outputs from a single module slot, which helps optimize I/O density in compact automation cabinets. Typical configuration options and electrical characteristics are defined by the Modicon 800-series documentation and the BMXAMO0410 family, which covers four independent outputs and corresponding signal conditioning. As with all Modicon BMX analog I/O modules, proper installation requires adherence to the system's grounding and wiring conventions and matching the module to a compatible Modicon controller and backplane configuration.
