Resideo R8845U1003/U universal switching relay 120VAC

Product Description

The Resideo R8845U1003/U Universal Switching Relay with internal transformer provides intermediate switching of line-and low-voltage devices from a line- or low-voltage controller, typically applied in hydronic heating systems. It facilitates 24V 2 or 3 wire thermostat control of line voltage devices, incorporating two line voltage SPST relays and one low voltage SPST relay with PowerPile rating.

• 120V Power Method
• Two SPST, plus PowerPile rated low voltage SPST relay
• Replaceable socketed relays

Product Highlights

Universal switching relay with internal transformer for line and low voltage devices. Ideal for hydronic heating systems with 24V thermostat control.
