The MTT MS3020 terminal block CT transmitter reads the AC current from a current transformer, calculates its true RMS value, and outputs a clean, standard DC signal your PLC, DCS, or data logger can use directly. True RMS calculation means the reading stays accurate even on non-sinusoidal current waveforms, which matters on loads driven by variable-frequency drives or other switching electronics.
Full isolation between input, output, and power keeps the transmitter safely separated from the monitored circuit while still delivering a clean, noise-free output signal. The compact DIN-rail housing mounts directly in the panel where the CT wiring lands, and front-accessible zero and span trimmers make on-site calibration quick.
It is a practical way to bring motor current monitoring, load monitoring, or general AC current metering into a standard control system without specialized power-metering hardware.
