6.2.2 Control terminal signals
Terminal Signal Technical information
1 +10 Vref Reference voltage Maximum current 10 mA
2 AI1+ Analogue input,
voltage or current
Selection V or mA with jumper block X1 (see page 44):
Default: 0– +10V (Ri = 200 k  )
(-10V…..+10V Joy-stick control, selected with a jumper)
0– 20mA (Ri = 250  )
3 GND/AI1– Analogue input common Differential input if not connected to ground;
Allows  20V differential mode voltage to GND
4 AI2+ Analogue input,
voltage or current
Selection V or mA with jumper block X1 (see page 44):
Default: 0– 20mA (Ri = 250  )
0– +10V (Ri = 200 k

)
(-10V…..+10V Joy-stick control, selected with a jumper)
5 GND/AI2– Analogue input common Differential input if not connected to ground;
Allows  20V differential mode voltage to GND
6 24 Vout
(bidirectional)
24V auxiliary voltage  15%; maximum current 250 mA all boards total; 150 mA
from single board. Can also be used as external power
backup for the control unit (and fieldbus).
7 GND I/O ground Ground for reference and controls
8 DIN1 Digital input 1
