Standard I/O board
Terminal Signal Technical information
1 Reference output +10 V, 0%...+3%, maximum current: 10 mA
2
Analogue input, voltage or cur-
rent
Analogue input channel 1
0...+10 V (Ri = 200 kΩ)
4-20 mA (Ri =250 Ω)
Resolution 0.1 %, accuracy ±1 %
Selection V/mA with DIP switches (see chapter 7.2.2.1 Selec-
tion of terminal functions with DIP switches)
