Pull up resistor value must be chosen in order to ensure ≥ 4 V at the GPI pin considering the input 30 kΩ
resistance. For Vcc 5 V, 1 kΩ is recommended. For 24 V 10 kΩ.
High speed (HS) digital inputs interface
The high-speed (HS) non-isolated digital inputs are ready for 5 V levels and tolerant to 24 V. Next table
shows their electrical specifications.
