OUTPUT - RS 422 - TTL

OUTPUT CIRCUIT

¹ Cable Shield:

for RI 30, 36, 58, 59, 76 and RX 70 connected to housing on encoder side

code letter	R = RS 422 + alarm³ (with UB = DC 5 / 10 - 30 V) T = RS 422 + Sense4(only with UB= DC 5 V)
Output signals clockwise rotation (cw) when looking at the shaft	rectangle pulse sequences (TTL) for channels A, B, N and their inverted Signals , A , B N
switching times with 1,5 m cable	≤100 ns ≤100 ns
Pulse shape
duty cycle	1:1
Tolerance¹	±25° electrical
Pulse frequency max.	300 kHz
Output voltage	DC 0 - +5 V ²
Output level	H ≥ DC 2.5 V / L ≤ DC 0.5 V (TTL level)
Output load max.	±30 mA
short-circuit resistance	for 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 proof through integrated regulation
reverse polarity protection from UB	for UB= DC 5 V: no with UB= DC 10 - 30 V: yes

¹ distance A to B at least 0.45 μs (at 300 kHz)
² also at UB= DC 10 - 30 V
