Technical information
Maximum current 10 mA
Selection V or mA with jumper block X1 (see page 72):
Default: 0– +10V (Ri = 200 k )
(-10V.....+10V Joy-stick control, selected with a jumper)
0– 20mA (Ri = 250 )
Differential input if not connected to ground;
Allows 20V differential mode voltage to GND
Selection V or mA with jumper block X2 (see page 72):
Default: 0– 20mA (Ri = 250 )
0– + 10V (Ri = 200 k )
(-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. 5k
i
18...30V = "1"
Must be connected to GND or 24V of I/O terminal or

Selection with jumper block X3 (see page 72):
Same as terminal #6
Same as terminal #7
R = min. 5k
i
18...30V = "1"
Must be connected to GND or 24V of I/O terminal or to
