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 top-adjust trimmer potentiometers can be used to make ne adjustments to output ranges for maximum exibility. This device can attenuate an input signal to 100%. The ARM2 also has an adjustable gain and oset. The output gain can be adjusted from 1 to 20 times the input (gain will vary depending on input). The ARM2 also has the ability to reverse an input signal. The ARM2 has a regulated 23 VDC power supply output to power sensors. The ARM2 can also accept a resistance input by using voltage divider applications. The ARM2 is eld calibratable, however, factory calibration is available upon request for an additional charge. This will speed up installation time for the end user.
