Table 4-2: Control I/O Terminal Signals on Option Board A9
Terminal Signal Technical Information
1 +10 Vref Reference voltage Maximum current 10 mA
2 AI1+ Analog input,
voltage or current
Selection V or mA with jumper block X1 (see
Page 4-8)
Default: 0 to +10V (Ri = 200 kΩ)
(-10V to +10V Joy-stick control, selected
with a jumper)
0 to 20 mA (Ri = 250 Ω)
Differential input if not connected to ground;
Allows ±20V differential mode voltage to
GND
3 GND/AI1– Analog input common
4 AI2+ Analog input,
voltage or current
Selection V or mA with jumper block X1 (see
Page 4-8):
