ABB CL2-623G Industrial Control Relay Modules

ABB CL2-623G is a 22 mm compact pilot light (indicator lamp) designed for panel mounting in control enclosures. The green LED indicator operates from 230 V AC and is cataloged as 1SFA619403R6232, the alternate ABB catalog number for CL2-623G. This 22 mm device fits standard ABB pilot-device cutouts and serves as a visible status indicator for automation equipment, PLC I/O, or safety interlocks. The CL2-623G designation identifies the green version of ABB’s 22 mm CL2 pilot-light family, offering a reliable signal source for panel-mounted indicators in electrical control panels, machine dashboards, and process equipment. Typical applications include indicating when a circuit is energized, signaling operational status in automation environments, or marking fault conditions in industrial settings. The device forms part of ABB’s compact pilot-light lineup and is used with ABB control stations and modular devices to provide quick, at-a-glance status communication in a range of industrial applications.
