EVOTM/RLY-4OR 4-Input OR Relay Control Unit


The EVO/RLY-4OR is a relay that is energized by applying 24Vac on any of four inputs.
The device is designed to allow thermostats and toher 24Vac devices to energize an outside air damper, valve, air cleaner, exhaust fan, ventilator, dehumidifier or other equipment whenever the thermostat calls for any function.
With this device, energized inputs do not feed back into the de-energized circuits.
The EVO/RLY-4OR may also be used with automation controller outputs to provide a logic function or save automation outputs.
