The Adtech Model ACA 142 AC Current/Voltage Dual Alarm accepts a standard AC current/voltage input signal and provides two (2) SPDT relay contact output setpoints rated at 10 amps; 30 VDC, or 250 VAC resistive.
An exclusive feature is that the input can be configured to accept either an "average" input (standard) or true rms input response (specify).
Integral dual color LEDs provide green indication for normal conditions and red indication on alarm setpoint independent of relay coil power.
