ARM - The ARM is an analog re-scaling module which accepts an analog voltage or current input signal and re-scales it to another voltage or current ouput singal. Several preset ranges are jumper selectable. The top-adjust trimmer potentiometers can be used to make fine adjustments to output ranges for maximum flexibility.  The ARM can attenuate an input signal to 100%. The ARM also has an adjustable gain and offset. The output gain can be adjusted from 1 to 25 times the input (gain will vary depending on input) to the ARM. The offset of the output can be adjusted anywhere from +/- 0 to +/- 20 VDC and can also accept a resistance input by using voltage divider applications. The ARM has the ability to reverse an input signal and has a regulated 20VDC power supply output to power sensors.  The ARM is covered by ACI's Two (2) Year Limited Warranty. Reverse or direct actin Field selectable ranges

ARM2 - The ARM2 will accept a single analog voltage or current signal and split that signal into two DC non-isolated current sourcing outputs that can be re-scaled. Its primary application is as a signal splitter. The outputs are always scaled identically and will always track each other. The ARM2 can be powered by a 24 VAC or VDC source.  It has an adjustable gain and offset and a regulated 23 VDC output power supply to power sensors and can also accept a resistance input by using voltage divider applications.  The ARM2 is field calibratable however factory calibration can be performed for an additional charge.  The ARM2 is covered by ACI's Two (2) Year Limited Warranty. Reverse or direct acting. Field selectable ranges

ASA - The ASA is an analog signal amplifier which accepts an analog voltage or current signal and outputs a voltage signal. Several preset input ranges are jumper selectable. ASA is designed to give a Building Automation System signal output the power (wattage) to control MaxitrolTM gas valves normally installed in rooftop units. The top-adjust trimmer potentiometers can be used to make fine adjustments of gain and offset. The output gain can be adjusted anywhere from 1 to 20 times the input on the ASA (gain will vary depending on type of input). The offset of the output can be +/- 0 to 20 VDC.  The ASA is covered by ACI's Two (2) Year Limited Warranty. Provides control of dimming ballast Low temperature applications (-40)
