Description –

The Pulse Duration Transmitter converts a 4/20 mADC signal to a periodic proportional modulated pulse width contact closure that is connected to a dry wire pair.

A Pulse Duration Receiver is connected to the other end of the dry wire pair that detects the modulated contact closure and converts it back to a 4/20mADC signal.

The 4/20 mADC signal may be connected to a local display, chart recorder or PLC.
