Allen-Bradley 855E-24TL3 PLC Digital Input Module

Allen-Bradley 855E-24TL3 is a 50 mm control-tower stack-light LED module that delivers a green, steady indication from a 24 V AC/DC supply. Designed for the 855E family of signaling towers, this socket-mount light module provides a crisp visual cue to indicate machine or process status within industrial control panels and production lines. The module operates on 24 V AC or DC (full-voltage configuration) and uses a green LED to offer long-life illumination with reliable visibility in harsh environments. It is intended to be installed in a 50 mm stack-light head via a standard socket-mount interface, enabling straightforward field replacement without removing the entire tower. Common applications include signaling normal operation or status changes on Allen-Bradley 855E stack-light assemblies in manufacturing automation setups, particularly where quick, unambiguous visual indicators are required for operators and maintenance staff.
