ARM | ACI: Analog Rescaling Module

The ARM is an analog rescaling module that accepts an analog (voltage or current) input signal and rescales it to another voltage or current output signal. Top-adjust trimmer potentiometers can be used to make ­fine adjustments to output ranges for maximum flexibility. The device 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). The offset of the output can be adjusted anywhere from 0 to +/- 20 VDC. The ARM can also reverse an input signal and has a regulated 20 VDC power supply output to power sensors. The ARM can accept a resistance input by using voltage divider applications.

The ARM is ­field calibratable. However, factory calibration is available upon request for an additional charge, expediting installation time for the end user.

For convenience in installing a complete building automation system, KMC Controls sells to our customers a large variety of ACI (Automation Components, Inc.) devices.
