Model 4MS | 4MSP (Potted) | 0-20mA, 4-20mA Current Transducers

Models: 4MS | 4MSP


The Model 4MS is an AC input current transducer with an internal 0-20mA or 4-20mA DC current loop transmitter that requires only two wires (the loop). The CT uses proportional conversion to obtain a true RMS DC signal from a pure sine wave. The output current is a standard process control 0-20mA or 4-20mA (select one when ordering). The current output requires an external resistor in the range of 200 to 1000 ohms (200 ohms being nominal) as the load resistor for the loop. The Model 4MSP is an encapsulated (potted), solid core version of the 4MS. This potting allows the unit to be used for outdoor use.
