Output signalsclockwise rotation (cw)when looking at the shaftrectangle pulse sequences(TTL) for channels A, B, Nand their invertedSignals , A , B N
switching timeswith 1,5 m cable≤100 ns ≤100 ns
Pulse shape
duty cycle1:1
Tolerance¹±25° electrical
Pulse frequency max.300 kHz
Output voltageDC 0 - +5 V ²
Output levelH ≥ DC 2.5 V / L ≤ DC 0.5 V (TTL level)
Output load max.±30 mA
short-circuit resistancefor UB= DC 5 V: only 1 channel for max. 1 s(standard RS 422 driver)with UB= DC 10 - 30 V: all channels fully short-circuit proofthrough integrated regulation
reverse polarity protection from UBfor UB= DC 5 V: nowith UB= DC 10 - 30 V: yes

1distance A to B at least 0.45 μs (at 300 kHz)
