Overview

The NSI Industries TRP-24B is a SPST 20A transformer/relay powerpack designed for 120/230/277VAC applications. This Class 2 power supply delivers 24VDC output at 150mA, enabling control of up to six TORK COS-L occupancy sensors or similar low-power devices. The TRP-24B features enhanced switching with inrush current limiting technology for extended relay life and zero-cross switching for reliable operation. Input voltage is automatically detected across 120/230/277VAC at 50/60Hz, making it compatible with most industrial and commercial power systems. Key applications include power and switching for occupancy sensors, light sensors, SS410 auto-off switches, and BAS-compatible demand shedding systems. The device supports momentary switching of loads with three control wires: red and black for 24VDC output, and blue for ON/OFF signals. Mounting is via ½" knockout for box installation. The TRP-24B operates reliably in temperatures from 32°F to 131°F (0°C to 55°C) and carries a 5-year warranty. Ideal for lighting control, HVAC systems, and automated switching where reliable low-voltage power and switching are required.
