I/O Connection
DIAP can be connected to PLCs, sensors or industrial robots via I/O connectivity. A breakout box is supplied together with the DIAP. Please pay attention when connecting the DIAP via the breakout box and follow the below instructions thoroughly to avoid damaging the DIAP and other equipment.
The I/O board is galvanically isolated from the DIAP CPU. It is possible to supply power to the I/O board directly from the power supply of the machine/line or from the power supply of the DIAP CPU.
The terminals on the breakout box are placed in the following way:
Sensor power supply
Please note that 24V DC must be applied to terminal 50 (+24V interface supply) with reference to terminal 49 (GND supply) for the sensor interface to be functional.

| 13 | CAN 1 HIGH |
| 16 | CAN 1 LOW |
| 19 | CAN 2 HIGH |
| 22 | CAN 2 LOW |
Connection of RS485
The isolated RS485 is connected using the following terminals, Bus termination is performed by means of connection J10 inside the diap.
| Terminal # | Signal |
| 44 | RS485-A |
| 47 | RS485-B |
| 43 | RE485-DEM |
| 46 | RE485-GND |
