Input capacitance: 0.1 ufd typical.
Maximum allowable voltage range on input: -0.5 VDC to 15 VDC.
Maximum frequency input: 100 Hz @ 50% duty cycle with de-bounce
enabled. 20 kHz @ 50% duty cycle with de-bounce disabled.
Dry contact (form A), open collector or active voltage.
Minimum contact resistance to activate input 1000Ω.
Voltage threshold to deactivate the input: 3.1V (referenced to GND
terminal).
Voltage threshold to activate the input: 0.5V (referenced to GND terminal).
Conductor pairs must be shielded to prevent spurious signals.
