Pt100 temperature transmitter 4 20ma MS181 - MS181

Pt100 temperature transmitter 4 20ma MS181

Detailed information

MS181 is an intelligent temperature transmitter module which can be programmed through a PC withConfiguration Kit. It has measurement input for resistance thermometers (RTD) ,thermocouples, resistances or millivolt signals in 2-,3- or 4-wire connection, and converts various input signals into a 4~ 20mA analog output signal after linear processing. Isolation is provided between the input and output. A special signal can be set in advance while the sensor burnout or short.
