3.10.Digital Outputs
There are four digital outputs on GV300TP for negative outputs (PIN7, PIN8, PIN14 and PIN15),
also three of them(PIN7, PIN8 and PIN15) can be configurable as positive outputs. As negative
outputs, all are open drain type and the maximum drain current is 150 mA; As positive outputs,
OUT3 (PIN7) outputs 5V powered for One-wire bus, and two others (PIN8, PIN15) can output
voltage 12V@200mA for 12V system or 24V@200mA for 24V system.
Each output has the
built-in over current PTC resettable fuse.
