ZSOM-Control Pinout description
The process I/O signals of the ZSOM-Control are available on two screw terminal blocks. The pin numbers are printed on the PCB next to the terminals:
- J8 (CON 1): pins 1–46 – digital inputs, analog outputs and analog inputs
- J9 (CON 2): pins 47–92 – switchable supply outputs, CAN, RS422/RS485, RS232, DIO and open collector outputs
With the PCB labelling readable (upright), J9 is the upper row with pin 47 at the top left, and J8 is the lower row with pin 1 at the bottom right. The table follows the connectors from left to right and shows opposite pins side by side (pin 47 is opposite pin 46, pin 92 opposite pin 1).
