The RS422 Interface Board RSB001 converts 5V TTL or CMOS single-ended encoder signals to RS422 differential signals. The ASSIST Interface Board and the ASSIST software allow to configure and/or program the encoder.

Input signals

single-ended 5V TTL/CMOS

Output signals

Differential RS422


0 – 2 MHz


5 V, 5 mA


-40 to 85°C

All ID-encoders with A/B outputs

All IT encoders with A/B/I outputs

RS422 interface Board RSB001 with dimensions and

1) connector to encoder,

2) connector to ASSIST Interface Board,

3) RS422 outputs,

4) input selectors for encoder 1 or 2,

5) jumper to select encoder supply voltage and

6) indication for inputs (encoder 1 or 2).
