Matching a sensor to a controller that expects a different signal, this analog rescaling module takes an analog input and reshapes it to an analog output across an adjustable span, converting between current and voltage on the way. A retrofit that would otherwise need a new sensor or a new controller is resolved at the panel instead, for the cost of one DIN rail module.

The ARM is an analog rescaling module which accepts an analog (voltage or current) input signal and rescales it to another voltage or current output signal. The top-adjust trimmer potentiometers can be used to make fine adjustments to output ranges for maximum flexibility. This device can attenuate an input signal to 100%. The ARM also has an adjustable gain and offset.
