US Digital HP Compatible Incremental Encoder Cable Driver PC5

The TTL outputs of some incremental encoders can sink (pull down) less than 4mA and source (pull up) less than 200uA. The PC5 is a small, plug-in RS-422 cable driver board that drives long cables up to 1000 feet using differential signaling to provide improved noise immunity. The PC5 can be used with the E2, E3, H1, H3, S1 and S2 encoders. Each board has a 5-pin socket designed to plug into the 5 pins of the encoder. An on-board 0.1uF bypass capacitor across the power pins on each of these boards compensates for inductance and noise which can be expected at the end of a long cable.
