3. Application Pinouts



Operation Channel Pull Normal State Rpi 4B Pin#



Signal Inputs Channel #1 Down LOW 11 (GPIO17)
Channel #2 Down LOW 13 (GPIO27)
Channel #3 Down LOW 15 (GPIO22)
Channel #4 Down LOW 16 (GPIO23)
Relay Outputs Channel #1 Hi-Z LOW 18 (GPIO24)
* Remarks
- This device has external pull-down registers for signal input ports. So, there is no need to use RPI internal pull-up/pull-down register.
