Product Description

Magnelab’s MCT-0024 is a 24-mm 4-20 mA Output Current Transducer that transforms an AC current of 250A to a 4-20 mA signal.

This 4-20 mA Output Current Transducer is powered from the 4-20 mA DC loop circuit. In most cases a loop voltage of 20 VDC is sufficient to power the device.  However, if you are using a shunt in the current loop to generate a detectable voltage (e.g. 250 Ohm), you must take the voltage drop across the shunt into account. Of course you may also provide additional voltage to the 4-20 mA DC loop if necessary.

The MCT-0024 is +/- 2% accurate at full scale. It has a response time of 100 ms.

4-20 mA output current transducers are popular because they differentiate a fault condition from zero detection. With the MCT-0024, when there is no current on the primary, the measuring device will still see a 4 mA signal.  Similarly, at the rated current, the measuring device will see 20 mA.  However, when the loop circuit is broken for any reason, as you’d expect, the measuring device will see 0 mA, and the unit detects an error condition.

Because of this special ability to detect error conditions, 4-20 mA Output current transducers are often used in control applications (you wouldn’t want to something to be controlled erroneously if the circuit was broken!).
