20-4The model 20/4 is a precision, loop powered 2-wire transmitter with galvanic isolation between its input and the current-loop output signal. The 20/4 provides the necessary circuitry for amplification and processing from Potentiometers and slide wires.Model 20/4L also provides input linearization to correct for non-linearity of sensors and specific applications.An optional LCD indicator is available on the 20/4 to indicate the output in Engineering Units.The 20/4 can be easily ranged without requiring special tools or board modifications. The transmitter is a member of Mescon's family of advanced Universal Input 2-wire transmitters which can be easily reconfigured to accept other popular input types such as RTD, Thermocouples and DC mV/mA/Volts. A TEST terminal provides a 40-200 mV signal proportional to the 4-20mA output. Applying a DVM to the TEST terminals allows monitoring and verification of the output without interrupting or disconnecting the current loop.
