Process Signal Conditioner SEM1600VI

The SEM1600VI process input signal conditioner is a powered isolator that accepts any voltage signal between -50V and +50V DC, or any current signal between -50mA and +50mA, and converts it into a voltage, bipolar voltage, or current re-transmission output. In current mode it can accept both active and passive mA signals on input and output, meaning it can either power a loop-powered transducer directly or accept a signal from an already-powered external loop.

A built-in user linearisation feature lets the output follow a non-linear input relationship — for example, linearising a pressure signal from an irregularly shaped tank to give a true level reading. Output signals can be scaled over any part of the input range, and an output alignment feature allows the actual input signal to be matched precisely to a user-set output value, giving process engineers fine control over calibration.
