Allen-Bradley 800E-4D3 Full Voltage Pilot Light Module

Allen-Bradley 800E-4D3 Full Voltage Pilot Light Module is a four-position, 22.5 mm round indicator designed for Allen-Bradley control panels. It operates from a 24 V power module and accepts 24 VAC or 24 VDC input to illuminate the pilot lamp, providing a clear visual cue for machine status in automation circuits. This full-voltage unit is built to snap into standard 22.5 mm pilot light cutouts and is commonly used in control ensembles where multiple signals are displayed side-by-side, such as indicating run, stop, fault, or ready conditions. As part of the 800E family, it complements other pilot light components to form compact multi-signal indicator arrays in panel installations, enabling quick, at-a-glance status checks by operators and maintenance personnel. The 24 V capability means it can be driven directly from standard control electronics without an external transformer, helping simplify wiring and reduce component count in control enclosures.
