Application

The RT850T Solid State Relay is designed to control a line voltage resistive load from a 24V control signal or dry contact. The relay is equipped with an LED for visual confirmation of load switching and can be used with a shortcycled thermostat (15 seconds) to provide precise temperature control. The RT850T has a built-in 24 V transformer and is compatible with 2-wire mechanical or battery-operated thermostats as well as 3-wire (R,C,W) thermostats.
