AAR Analog Input to (2) Adjustable Relay Outputs

The AAR is controlled by a single analog input signal with two potentiometers controlling each output relay. The two 10 amp output relays can be independently set to fixed or adjustable deadband. An onboard deadband selector can be set to Fixed or Adjustable. “Fixed”, the relay will turn “ON” at the level set by the Low pot and will turn “OFF” at a fixed 3% of the input signal below the turn-on level.

“Adjustable” allows a flexible range of deadband adjustment using the High and Low potentiometer. The edge-connector feature allows signal and power connections to be extended to the next board. This allows the installer to wire the first unit then slide additional units up against it, plugging into a power and signal bus withoutbthe need to strip and terminate additional wires. AAR’s are equipped with plug-in terminal strips.
