Digital I/O
• All DIOs programmable as
- Input (default)
- Push-pull output
- Open collector output
• Input voltages max 30 V, reverse polarity protection
• 24 V logic levels for input: “0” < 5 V, “1” > 15 V (according to
standard IEC 61131-2)
• Input impedance 2 kOhms
• If more than two digital outputs are used, current source is
25 mA. Otherwise current source is 50 mA. Current sink is
500 mA.
• Outputs are short-circuit proof
• Galvanic isolation as one group
Relays
• 240 VAC, 2 A resistive load
• 30 VDC, 5 A resistive load
• Varistors for inductive load protection.
• Reinforced isolation between channels and channel and ground
