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

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:

• Temperature sensor T811 — up to 8 pc.;
• Humidity sensor WS-2 — 1 pc.;
• NetPing IRC-TR v2 — 1 pc.;

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

Sensors of the "Dry contact" type

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.

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.

Such type of sensors include:

• Supply voltage sensor
• NetPing Supply Voltage Sensor 995S2 (N.Z. and N.O. contacts (3 wires in total) - see the sensor documentation for details);
• Door sensor metal
• Air Flow Sensor (model AMC520)

Liquid sensor (mod.2605)

PIR DETECTOR (mod.M105-1E)

Actuation Devices

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.

Buzzer (mod.STD-3025)

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

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.
