Electric adapter EA

for rotary encoders

The EA-D-L-10- is a differential RS-422 cable driver which converts the single-ended A/B/I output from USD's single-ended incremental encoders (or any three TTL level digital signals) to 3 pairs of differential signals. This allows the encoder to drive long cables (up to 1000 ft.) and reduces false switching in noisy environments. Various connector options are available on the 5-pin input side of this adapter. The output differential signals are available on a male 10-pin latching connector (FH10). The differential signal from the EA-D-L-10- can be connected directly to USD's QSB-D and USB4-D interface products. The corresponding receiver, EA-R-L-10- converts the received differential signals back to 3 single-ended TTL level digital signals. The differential input side of the receiver is a 10 pin male latching connector (FH10). Various connector options are available on the single ended 5-pin output side. The EA-D-H-10- is the same as the EA-D-L-10-, but offers a wide operating voltage range of 7.5 to 30VDC and a large output voltage swing proportional to the power supply voltage. This adapter allows 5V encoders to be used in high voltage applications.
