The MTT MS3120 terminal block CT transmitter reads the AC current from a current transformer, calculates its true RMS value, and delivers it as two independent, isolated DC outputs from a single unit — useful when a current reading needs to reach both a control system and a separate recorder or alarm. True RMS calculation keeps the reading accurate on non-sinusoidal current waveforms, which is common on loads driven by variable-frequency drives.
A choice of AC or DC power lets it fit panels without a dedicated low-voltage supply, and full isolation between input, both outputs, and power keeps the transmitter safely separated from the monitored circuit while delivering clean signals to every connected device. The DIN-rail housing mounts directly in the panel where the CT wiring lands.
It is a practical way to distribute one motor or load current reading to two separate monitoring or control systems without dedicated power-metering hardware.
