SEM1750 Signal Conditioner
Brand: Status InstrumentsThe SEM1750 is a cost effective dual channel signal conditioner that accepts a bipolar voltage or current signal and isolates to provide ranged industrial process output signals such as (0-20) mA, (4-20) mA, (0-10) V, (1-5) Vdc.
The SEM1750 is configured using our easy to use configuration software USB Speed Link.
USB speed link offers the user two levels of configuration: a basic current/voltage signal converter where the device can be set as dual channel or signal splitter, or for more advanced applications, a configuration menu offering a wide range of user set functions, including process scaling and profiling, maths functions, signal damping, sensor linearisation and signal preset for diagnostics purposes.
