Voltage drop:
< 0.3 V at 500 mA for O6 and O7
< 0.7 V at 500 mA for I/O2...I/O5
Total current per module:
3 A steady load
Switch-on delay:
typically 10 µs
Switch-off delay:
50 μs typically (100 μs max.), (ohmic load 5..500 mA),
longer for inductive load because of protective diode.

If the state of a combined output is to be read off,
voltage U

, as the state and the LED are displayed via the
input.
