[ENG] [2PWR,v2SMS] Using IO Lines in the «Output» Mode to
Control External Devices
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).
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
. In addition, we can advise ready assembly relays of
other manufacturers, which can be connected to our devices:
BM8070D a power relay 16
А
/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.
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!
