ACI AAR : Analog Input, Relay Output, 2 (SPDT) Relays

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. “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 both 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 together by plugging into a power, and
signal bus without the need to strip and terminate additional wires. The AAR is field calibratable, however, factory calibration is available upon
request for an additional charge. Relay trip points can be factory calibrated, saving installation time and expense.
