2-4 Digital Input / Output / Watch Dog Time
2-4-1 TB2-TB 8pin connector (3.5mm)
Note：
F75111N-1 I2C bus address 0x9C.
DI input range is +12V or +24V.
DI pin default pull up 10KΩ to +3.3V.
DO output voltage rail from DC-in(+12V or +24V) and current limit max 2A.
For F75111N I2C watch dog timer device:
Input low Voltage (VIL):+0.8 Max,
Input High Voltage (VIH): +2V Min
Output low Current (IOL):10mA (Min) VOL=0.4V
Output High Current (IOH):-10mA (Min) VOL=2.4V
Watch Dog Time value 0~255 sec
The system will be issued reset. When WDT is enable the hardware start down counter to zero. The reset timer has 10~20% tolerance upon the Temperature.
