MCT-0016 4~20 mA Output AC Current Transducers by Magnelab

Description

The MCT-0016 Split Core Current Transformer series have a 4~20mA DC (4-20mA) output with a 16 mm opening

• The MCT series measure AC current 5 Amps up to 100 Amps (model dependent)
• This 4~20mA Output CT is powered from the 4~20mA 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 4~20mA DC loop if necessary
• The MCT-0016 is ± 2% accurate at full scale
• Ripple within 2% of output voltage
• It has a response time of 100 ms
• 4~20mA CTs are popular because they differentiate a fault condition from zero detection
• With the MCT-0016, 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, 4~20mA Output CTs are often used in control applications (you wouldn’t want to something to be controlled erroneously if the circuit was broken!)
• The MCT-0016 can be easily used in retrofitting applications because the split core current transformer opens and closes easily
