Analog IO Board (AIO_I2C)
Analog Inputs: -20 to 20mA into 50Ω or -10 to 10V,
R10=1MΩ, mutually isolated 10V
Analog Outputs: 0-4 to 20mA. Common negative
pole, galvanically separated from ground, freely con‐
nectable to ground; working resistance 750Ω.
Digital Inputs: Optocoupler with internal 12-24VDC
power supply, switchable with floating contacts; alter‐
native: switchable with external voltage 12-24VDC,
common negative pole.
I/O Terminal Design: Plug-in terminal strips for stran‐
ded or solid conductors with a maximum diameter of
1.0mm or 18AWG.
