The inputs can be connected directly to +5 V. If a higher voltage is used, an
external resistor must be placed in series. Use at +12 V a 820 Ω resistor and
at +24 V a 2.2 kΩ resistor.
The optocoupler inverts all input signals. Inversion of the signal is controlled
via the IO_INP_CTRL1..2 register (see Table 33: Input configuration register
on page 95).
Flux voltage from LED type 1.5 V at 10 mA
Initial on-current: 5 mA
Max. off-current: 0.25 mA
Max. input current: 15 mA
Min. pulse width 2.2 µs

Caution
a
Voltages above +45 V may damage the optical coupler.
