RELAYS
Resideo’s switching relays are available in multiple
congurations for various applications. For whatever you need
— general purpose relays or electric heat relays — Resideo has
you covered.
GENERAL PURPOSE AND HEAVY-DUTY SWITCHING RELAYS
R4222, R8222, R4228 and R8228 for use in refrigeration and air
conditioning equipment, appliances and vending machines.
TIME DELAY RELAY
ST82 combines the R8222 or R8228 relay for use in
compressor-run air conditioning and heat pump systems; this
product features an electronic timer that delays blower shut off
after the compressor has shut off.
FULLY ENCLOSED LINE AND LOW-VOLTAGE FAN RELAYS
R4225 and R8225 for control of line voltage fan motors and
auxiliary circuits.
ELECTROMECHANICAL RELAYS FOR CONVENTIONAL
24 V THERMOSTATS
• RC840 for use with two or three-wire thermostats to control
baseboard, convectors, radiant ceiling and duct heaters.
• Immediate relay activation, improved temperature control and
comfort, no 90-second on/off delays as with thermal relays.
• Epoxy soundproong, quiet operation.
• Terminal board connection, easier installation uses less space.
TRIAC RELAY FOR PULSED OUTPUT THERMOSTATS
• RT850 for use with two or three-wire thermostats to control
baseboard, convectors, radiant ceiling and duct heaters.
• Superior temperature control when used with fast cycling
thermostats.
• 100% silent solid state relay switching.
