The PM21S provides two functions in one easy-to-use product. As a
receiver, it accepts differential line driver signals and converts them to
single ended signals for use with counters and indicators. This unit is
located near the counter or indicator and allows input signals to travel
long distances without degradation and with higher noise immunity.
As a power supply, it also provides a power source for encoders,
pickups and other devices that have high current requirements.
The differential receiver and power supply operate independently, so
only the features that are required need to be connected. All field
connections are made through a terminal strip which accepts number 22
through 12 AWG.
