About Relay Drivers
Relays are devices that can provide power directly to external devices that have modest power requirements, such as the small fans used in our Bowen ratio systems. Alternatively, these relay drivers can provide control signals to heavy-duty external relays that in turn can control power to heavy-duty, high-power equipment such as ventilation fans, aquacultural aerators, refrigeration units, or other electrically powered machinery.
