Honeywell R8845U1003 SPST Universal Switching Relay

The R8845U Universal Switching Relay with 24 V transformer provides intermediate switching of line-and low-voltage devices from a line- or low-voltage controller and is typically applied in Hydronic heating systems.

Features: Replaceable socketed relays. Two troubleshooting LED. Push-to-test button. Replaceable transformer fuse. Low-voltage contact rating for PowerPile® applications. Long-life DC relay drive control technology. Relay for use with external 24 Vac or 24 Vdc supply, with line-voltage control, or with internal 24 V transformer supply. One model replaces many competitor models. One model may replace many Honeywell models:R182A,B,C,J; R482A,B,C,J; R845; R882A,B,C,J and RA832.

Applications: Enclosed Universal switching relay with internal transformer for 24 volt 2 or 3 wire thermostat control of line voltage devices. Two line voltage SPST relays and one low voltage SPST relay with PowerPile® rating.
