Input-Output (IO) lines of a device can be used for an input work as well as in an output mode for managing external devices.

A device has four IO lines, corresponding to contacts I1 – I4 of a terminal block. Lines configuration for work as an input or an output is made through a controlling web-interface of a device. All four IO lines can be customized independently.

Lines management can be done by SNMP commands, URL-encoded commands, via a web-interface or using SMS-commands (for devices with built-in GSM modem).

Such device functions as a watchdog and scheduled load management are NOT AVAILABLE for IO in an output mode.

Examples of using:

  • Remote servers reboot – an imitation of pressing “reset”;
  • Remote management of an alarm, a light, a fan;
  • Management of an electric lock, electric gates on a remote object;
  • Management of smart home elements - watering flowers, opening-closing louvers, water pump, heating boiler, heaters, etc.
  • Remote management of a power installation (diesel generator, gasoline).

Important! Correct electrical coordination of IO lines is required when connecting external executive devices.

Important! IO lines do not have galvanic isolation with a device! Remember about electrical safety when using relays that commutate 220 V circuits. All work must be done by specialists with a correspondent qualification who have a permit to work with such a voltage!

It is acceptable to use intermediate relays with a power supply voltage 12 V from an external source. A ready socket can be used for IO lines connection NetPing AC/DIN socket. In addition, we can advise ready assembly relays of other manufacturers, which can be connected to our devices:

  • BM8070D a power relay 16А/250V for DIN-rail (check out the compatibility of this relay with the NetPing device model on the relay web page on the site);
  • MP701 a power module switch (4 independent channels, 2 kW 10A each) (check out the compatibility of this relay with the NetPing device model on the relay web page on the site);

Electric parameters of IO lines

In the «output» mode:

  • the voltage of logic «1»: +5 V, resistance: 3,3 kOhm;
  • the voltage of logic «0»: 0 V, resistance: 51 Ohm.

In the «input» mode:

  • voltage of logic «1»: > 2 V;
  • voltage of logic «0»: < 0,8 V.
