[ENG] [DKST 51] Connecting External Sensors and Accessories

It is prohibited to plug sensors and external modules into NetPing devices when a power supply is on!

You can find the information about configuration of the device and receiving notifications from sensors in the document: «User Guide».

The description of contacts

In order to connect sensors to the device conveniently, use the terminal block. Use a slotted screwdriver with a slot width of 2.5 mm to secure the wires in the terminal block. The pinout of the contacts on the terminal block is as follows:

i2C Connecting sensors and devices to the i2C bus

Devices and sensors are connected via a 4-wire circuit. The color of the loop wires is identical for all sensors and devices manufactured by NetPing east Co Ltd.

Only sensors and devices of own design are supported, these include:

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. Otherwise, it can be done independently with the help of any wire with a minimum cross section of 0,4 mm2. Maximum allowable length of a flat cable is 10 m from each sensor to a device (star topology).

All sensors and devices are connected in parallel to each other in the same terminal blocks according to the following scheme:

Important! It is prohibited to connect temperature sensors with the same numbers (ID) to the device.

Set each temperature sensor with its own number using the switches on the sensor board. To set the switches, remove the top cover of the sensor 

Depending on the ID, the temperature sensor will be displayed on the corresponding channel in the device’s web interface.

Sensors of the "Dry contact" type

Attention! There are 12 V, up to 200 mA on the input / output lines of the device (IO1-IO4) in the “output” mode, . If used improperly, the connected equipment may fail.

The number of connected dry contact sensors is limited by free IO lines of the device and the total current consumption of the sensors, if they require additional power.

If the sensor needs extra +12 V power, you need to use one of the input / output lines in the "output" mode. Thus, it is possible to control the power of the sensor additionally using a logical level on the line. This can be useful, for example, in the case of sensors whose alarm is reset by removing power. 

If the factory cable length is not enough, it can be increased by using Cable 4 extender, 4m, which are connected to each other sequentially , or independently using any wire with a cross section of at least 0.4 mm2.

The maximum permissible loop length is 100 meters.

The corresponding IO line to which the signal wire from the sensor is connected must be switched to the “input” mode in the device settings.

Two wire sensors

Sensors and other signal sources which do not require additional power or they are powered from other power sources and it is isolated from the signal line, connected to the IO and GND terminals of the device. The polarity of the connection is important unless otherwise directly indicated in the documentation for the sensor.

Actuation Devices

Attention! There are 12 V, up to 200 mA on the input / output lines of the device (IO1-IO4) in the “output” mode, . If used improperly, the connected equipment may fail.

The number of actuation devices is limited by  free IO lines of the device and the total current consumption of devices in active mode.

If the device requires +12 V power, one of the I / O lines in the “output” mode is used.

If the factory cable length is not enough, it can be increased by using Cable 4 extender, 4m, which are connected to each other sequentially , or independently using any wire with a cross section of at least 0.4 mm2.

The maximum permissible loop length is 100 meters.

The corresponding IO line to which the signal wire from the sensor is connected must be switched to the “input” mode in the device settings.

The logic level on the line in the “output” mode which is used for power will control the operation of the buzzer. When the log.1 - the buzzer is active, with the log. 0 - the buzzer is off.

NetPing AC/DIN socket uses a relay with normally closed contacts to switch the load. This means that if the control wire is not connected anywhere, 220 V will be present on the socket and the load will be turned on.

In the "log.0” condition, 220 V will be present on the IO control line at the output of the socket, the load will be turned on. In the "log.1” condition the socket will be de-energized, the load will be off.

Important! The brown (white) wire is not used and should not be connected!
