The SEM1750 is a dual channel signal conditioner designed to accept mA or voltage inputs and provide isolated, industrial process output signals in mA or Volts.
Each output channel may be linked to either an input signal or to a maths function of both input signals.
This powerful feature allows the device to operate in several different modes.
The product has transmitter power supplies built into each input so can power temperature, pressure, level, humidity etc transmitters.
Using maths functions in the device, average, sum, highest, lowest can be selected to provide a function of the two input signals.
It can also be used as a splitter, dual channel isolator and has a user non linear feature to allow, for example, tank measurement.
So, for example, you could have two level sensors connected to two non linear tanks.
The product can linearise the tank’s volume to the output signal. Then, if required you could do maths functions on the linearised outputs such as average, difference etc.
The output signal(s) can also be programmed for any value between (0 to 20) mA or (0 to 10) V.
