Allen-Bradley 100-D24 Plug-In Relay

The Allen-Bradley 100-D24 Plug-In Relay is a miniature ice-cube, plug-in relay designed for switching and isolating low-power circuits in industrial control systems. It supports coil voltages of 24 VDC and 120 VAC, mounts via socket (8-, 11-, or 14-pin depending on the relay), and uses plug-in blade terminals; contact configurations may include SPDT, DPDT, 3PDT, or 4PDT with ratings typically 6 A to 15 A depending on the model. Widely used in PLC control panels and automation equipment, HVAC systems, packaging lines, conveyors, and OEM machinery, it serves maintenance teams and system integrators for replacement, troubleshooting, panel retrofits, and machine control. Selected models also offer LED status indicators, mechanical flags, and push-to-test/manual override functionality.
