SEM1720 Dual Channel Signal Conditioner
Brand: Status InstrumentsSEM1720 is a dual channel signal conditioner designed to accept RTD, Thermocouple or Potentiometer sensors and provide isolated, industrial process output signals in mA or Volts.
Each output channel may be linked to either input sensor or to a maths function of both sensor signals.
This powerful feature allows the device to operate in a number of different modes.
SEM1720 is configured using the free USB SpeedLink software that allows the user to configure the device without requiring calibration equipment.
Maths functions on each channel can be set up using the software as well as a 22 segment profile tool. Input output simulation tools for diagnostic purposes are also available. Thanks
