Isolated Process Receiver
These inputs are individually configurable to accept either a -10/0/+10V input
signal or a 4-20 mA signal. When configured for voltage input, each channel
has an input impedance of 75 K Ω. When used as a current loop input, the
transmitter must have a minimum loop compliance of 2V to satisfy the 100 Ω
input impedance. Regardless of input configuration, each input is individually
isolated to ± 100V DC or 70V RMS AC.

The receiver can accept 4-wire transmitters. The figure below shows the
recommended connections. Again, the type of shielded cable used is
application specific as per the transmitter.
