The MC can trigger a relay and record a digital input signal. The relay is switched by commands that are received via a TCP or UDP socket.

The digial input signal can be sampled in a defined time interval. The status of the signal can be send via LAN or WLAN to an application. The used protocol is UDP.

The teminals of the relay change over switch and the digital input can be connected over the connector for the power supply. The pinning depends on the design of the power connector.
