Output
ARM2
Analog
Analog Current or Voltage to Dual 4-20 mA Output
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 rescaled. Its primary application is as a signal splitter.
The outputs are always scaled identically and will 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 is available upon request.
The ARM2 is covered by ACI's Two (2) Year Limited Warranty. The warranty can be found in the front of
ACI's Sensors & Transmitters catalog, as well as on ACI's web site, www.workaci.com.
