Plugging NetPing AC/DIN sockets
The number of plugged
NetPing
AC/DIN sockets is limited only by a number of free IO lines.
When connecting a socket to a device, all wires are used, except a brown (white) one. An IO line, to which a
NetPing
AC/DIN socket is connected, needs to be switched into the «output» status. When a status is «logic 0»,
220V will be present on an IO line, and a load will be switched on. When a status is «logic 1» on an IO line, a socket
will be de-energized, a load switched off.
Important! A brown (white) wire is not used and must stay unplugged!

To commute a load
in NetPing
AC/DIN, a relay with normally closed contacts is used. This means that if a control
wire is unplugged, 220 V will be present in a socket, and a load will be switched on.
A sensor is packaged with an inseparable cable, with connectors on the ends. A cable length can be increased with
the help
of flat cable extenders of
RC-4 sensor, which are sequentially plugged one into another. Or it can be done
2
independently with the help of any wire with a minimum cross section of 0,4 mm
. Maximum allowable length of a
flat cable is 100 m.
