GO-RP2040-CB08

Terminal and relay layout of the GO-RP2040-CB08 board

ItemSpec
Power inputDC-INPUT + −, DC 24 V (18 to 36 V)
Digital inputs4 (IN01 to IN04, common COM). Photocoupler isolated, non-polar, DC 24 V
Relay outputs4 (OUT1 to OUT4, common COM). NO contact, 5 A 250 VAC / 5 A 30 VDC
Analog2 ADC, 2 DAC
CommsRS-485, 2 channels (CH1, CH2)
PC connectionUSB Type-B (USB DownLoad)
Indicators4 input LEDs, 4 output LEDs

2. New project and main board

The Main board (unassigned) item in the Board box on the right of the project page

Once assigned, the Board box changes to this.

ItemState
Target BoardTop of the Board box. Switches to Raspberry Pi Pico on its own
AddressesInputs P0 to P3, outputs P4 to P7. Change them under I/O Mapping
Use Ethernet moduleLeave it off. Turn it on only when an Ethernet board (GO-LINK W5500) is attached
Slots 1 to 9Places for expansion cards. Left empty in this series

The Test project is used through Part 3.

3. Select the port
