[ENG][2PWR] Using IO Lines in the «Output» Mode for Controlling
External Devices
Input-Output (IO) lines of a device can be used to operate as "input" as well as the "output" to manage external
devices.
A device has four IO lines, corresponding to contacts I1 – I4 of a terminal block. IO lines are configured for the
operation as an input or an output using a controlling web-interface of a device or using URL-encoded commands.
All four IO lines can be customized independently.
IO lines can be controlled by SNMP commands, URL-encoded commands, via a web-interface or using SMS-
commands (for devices with a built-in GSM modem).
Use cases include the following:
Rebooting remote servers – 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 controlled
socket
can be used for connecting IO lines
. In addition, we can advise ready assembly relays,
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 executive element (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»: push-pull 12V, up to 200mA;
the voltage of logic «0»: 0V, up to 200mA.
The
push-pull mode allows controlling the loads, such as LED beacons, sirens, power relays without intermediate
relays and signal amplifiers.
In the «input» mode:
the voltage of logic «1»: > 8,2 V;
Caution!
There is 12V and up to 200 mA at the input/output lines (l1-l4) of the device in the «output»
mode
(not a typical "discrete output"). If used not right, the connected equipment may fail.
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 corresponding qualification
who have a permit to work with the voltage!
