Allen-Bradley 856T-B24C

Allen‑Bradley 856T‑B24C is the 70 mm upper‑base power module for Rockwell Automation’s 856T stack‑light towers, delivering 24V AC/DC operation in a black housing with a push‑in terminal block and a cap included for a ready‑to‑install top section. When paired with a 856T base assembly and mounting adaptor (for example 856T‑BMASN for a surface‑mount base), it completes a configurable 70 mm signaling column used to provide visual status indications within control panels and automation equipment. The 856T‑B24C occupies the 70 mm footprint and is designed to be used as the upper‑base portion of the signaling tower, compatible with the 856T base assemblies per Rockwell’s selection guidance. Originating from Austria, this part is listed under the 856T product family and carries the 24V AC/DC power specification for stack‑light operation. Typical deployments include machine status signaling, process indication, and fault or ready indicators in industrial automation installations.
