Analog and Digital I/O Board (ADIO_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, galvani‐
cally separated from ground, freely connectable to ground; work‐
ing resistance 750Ω.
Digital Inputs: Optocoupler with internal 12-24VDC power supply,
switchable with floating contacts; alternative: switchable with ex‐
ternal voltage 12-24VDC, common negative pole.
Digital Outputs: Digital Outputs: Floating double-throw contacts,
max. contact load rating 30V / 1A
I/O Terminal Design: Plug-in terminal strips for stranded or solid
conductors with a maximum diameter of 1.0mm or 18AWG.
