8.17.4.4 Open collector output
This output can be used to drive external relay. In order for the output to work correctly, external voltage that is
connected to a relay also needs to be connected to I/O header pin 4. There is flyback diode located inside the device to
protect it from spikes occurring when inductive load (relay coil) is suddenly switched off, so connection of the external
diode is not necessary. The output is isolated from the rest of the circuitry using optocoupler. In case of the output
failure, the rest of the circuit will remain protected.
Maximum external DC voltage
30V
Maximum output sink current
0.3A
Example of driving a relay:
