Technical information
Maximum current 10 mA
Selection V or mA with jumper block X1
Default: 0– +10V (Ri = 200 kΩ)
(-10V.....+10V Joy-stick control, selected with a jumper)
0– 20mA (Ri = 250 Ω)
Differential input if not connected to ground;
Allows ±20V differential mode voltage to GND
Selection V or mA with jumper block X2
Default: 0– 20mA (Ri = 250 Ω)
0– +10V (Ri = 200 kΩ)
(-10V.....+10V Joy-stick control, selected with a jumper)
Differential input if not connected to ground;
Allows ±20V differential mode voltage to GND
±15%, maximum current 250mA (all boards total);150mA
(from single board); Can also be used as external power
backup for the control unit (and fieldbus)
Ground for reference and controls
R = min. 5kΩ
