Signal Conditioners with Universal Input

Universal input conditioners/isolators accept a wide range of RTD, thermocouple, resistance, potentiometer, mA or voltage inputs, and offer current, voltage and/or relay outputs with programmable ranges and functions. Units can be configured by using a detachable programming module that also displays the input signal value, engineering units, output signal and relay status.
