description».
Sensors and devices of the 1-wire model range
The sensors of the 1-Wire model range are connected with 1-wire plugs RJ12 with the possibility to use extension
cords and splitters. The maximum loop length of 1-wire network, connected to one connector is restricted to 50
meters. It is possible to connect up to 2 temperature sensors and 2 humidity sensors in total at the same time.
To the 1-wire sensors belong:
•
Temperature sensor 1-wire
•
Humidity sensor 1-wire (HS)
Sensors of the "dry contact" type
The number of the connected sensors of the "dry contact" type is restricted by free input lines of a device and total
current consumption of the sensors if they need additional power supply.
If there is not enough factory cable length, you can extend it using
sequence into each other, or independently using any wire with a cross section of at least 0,4 mm
The maximum permissible length of the cable is 100 meters.
Sensors with two wires
The sensors or other sources of signal, which do not require additional power or they are powered by the other
power sources and it is isolated from the signal line, are connected to the IN terminals and GND terminals of the
device. The polarity of the connection is not important unless otherwise indicated in the documentation for the
device.
To this type of sensors belong:
•
Supply Voltage Sensor 995S2
•
NetPing Supply Voltage Sensor 995S2
•
Door sensor metal
•
Airflow sensor + GRID 120 * 120 * 10mm NC
•
and other.
Liquid sensor (mod.2605)
This sensor is not an independent device. it is designed to operated together with a special sensitive
