Switching capacity for relays (SSR) - max. current 100mA ~/=, max. voltage - up to 30V.
When using shielded Ethernet cable its shield will connect to GND terminal, which in his turn recommended to wire to ground for better noise protection.
Voltage input 24V +/- 10% (15%).
Connector for external WiFi antenna is RP-SMA type jack. It is compatible with many other available antennas.
WiFi antenna has SMA plug.
It is possible to connect various USB2.0 devices like RS-485, RS-232 ports, USB hubs, 3G and 4G modems, etc. Max load is 5V 500mA.
