Honeywell Electromechanical Relay - RC840/U

The Honeywell Electromechanical Relay is designed to control a line voltage resistive load from a low voltage thermostat. With a 24V, 40 mA, 1 VA control signal, it provides on/off switching and comes complete with a lock-nut.

This unit serves as a direct replacement for any brand name relay, facilitating seamless integration into existing systems. Compatibility extends to 24V thermostats with either 2-wire connections (R,W) or the more complex 3-wire connections (R,W,C), enhancing its adaptability.

A hallmark of the Electromechanical Relay is the immediate relay activation which offers enhanced temperature control and overall comfort. The relay features an epoxy-soundproofed design, ensuring quiet operation that will not interrupt your daily operations or environment.

The terminal board connection enables easy installation, making it a user-friendly choice for all levels of expertise. The low current consumption quality of this device signifies that multiple relays can be controlled by a single thermostat, heralding efficient power use and the potential for cost savings in the long-term.
