The FS80 has an auxiliary I/O interface with seven optically isolated auxiliary signals.
Four inputs support sinking and sourcing configurations and can receive 24 V.
Three outputs support sinking configurations and operate at up to 24 V nominal. If you connect one of the outputs in a sourcing configuration, the other two outputs are no longer available.
Sinking and sourcing concepts refer to conventional current flow, which means current flows from the positive potential toward the negative potential. A sinking device provides a path to sink current towards the ground or the return path; it does not provide power. A sourcing device provides a path that sources current and a path from the power source.
In the following diagram, the device on the right is the sourcing device, and the device on the left is the sinking device.

When setting up auxiliary I/O, ensure you configure the GPIO pins in Aurora Focus.
