Function:
The NTC-XX-PDX family of instruments make up a pulse duration transmission system that can be used to transmit an analog signal over a twisted pair (or a leased class A telephone line). The transmitter can have any one of the standard inputs such as 4-20 mA, 1-5 VDC, etc. The receiver can have any one of the same or a different analog output.

The output of the transmitter is a dry contact but can be an optional 24 VDC pulse. Correspondingly, the input of the receiver can accept either a dry contact or a 24 VDC pulse.
