DO: at present, this version takes the power supply voltage limit as the maximum
voltage, that is, the maximum input voltage is DC 36V; The typical input current
can reach 450mA.
Supplement:
1.The above DIis the voltage range given for the external wet contact. At this
time, the internal pull-up of VG814 cannot be used.
2. When the di external is connected to the dry contact, the vg814 can provide 12V
pull-up level internally, and the pull-up resistance is 20K Ω.
3. When do is used as open drain output, the typical perfusion current can reach
450mA.
4. When do pull-up is used as output, it can output high-level signal. The open
circuit test voltage is 12V, and the pull-up resistance is 20K Ω. It has no load
capacity.
VG814 vehicle version
Power input range: DC 9V ~ 48V.
DI: at present, this version takes the power supply voltage limit as the maximum
voltage, that is, the input voltage range is DC 0V ~ 48V; It is determined as low
below 1V and high above 2.7V.
DO: at present, this version takes the power supply voltage limit as the maximum
voltage, that is, the maximum input voltage is DC 48V; The typical input current
can reach 450mA.
Supplement:
1. The above DI is the voltage range given for the external wet contact. At this
time, the internal pull-up of vg814 cannot be used.
