Honeywell RC840T-277 24V-277V TRANSFORMER RELAY 24V-277V TRANSFORMER RELAY

24V-277V TRANSFORMER RELAY

The Honeywell RC840T-277 24V-277V TRANSFORMER RELAY is designed for use with select Honeywell zone controllers that utilize 24V-277V transformer wiring. It can be used as a backup, or it can be wired to work independently of the zone controller. Includes required wiring.

The Honeywell RC840T-277 24V-277V TRANSFORMER RELAY is a replacement relay for use with electronic air cleaner systems.

Honeywell RC840T-277 24V-277V TRANSFORMER RELAY is for use with Honeywell/Ademco intruder alarm keypads to connect the devices to a central monitoring station.

The RC840T-277 24V 277V transformer relay has a molded plastic case and is designed for use as an intermediate power supply between the auxiliary winding of a high voltage DC power supply and the miniature load. The relay contacts can be operated either directly by DC or by using standard 12 VDC magnetic snap action switches. The relay state either remains unchanged or switches to the opposite state while the control voltage is in effect.

The RC840T-277 24VAC / 277VAC transformer relay is used as a voltage converter in control systems. The RC840T-277 is an EMITTING relays that turns on when the voltage goes below 32VDC and off at 33VDC. It is used to control the 12V LED light strip.

The RC840-277 is a solid state, PSC controlled, single-phase, 277/480V 3VA Transformer Relay. It is designed to energize a relay for transformer disconnect and reconnect in dual-pole applications. The relay uses a standard dual-throw solenoid coil having an operating current of 250mA at 24VAC.
