Inputs Rx are designed to measure resistance in the range 1-100kOm. | |||
Measured resistance is connected between the GND and Rx. | |||
For a more accurate measurement of resistance, as well as to connect Pt100, Pt1000 and for two- and three-wire circuit | |||
is a special [[Special:MyLanguage/Wiren Board 5: Модуль расширения ADC| extension module]]. | |||

These devices form a signal by closing two wires. | |||
Connection Methods to the controller: | |||
* | * With Ax terminal controller. Connect one wire to the power supply 5-24V, the second wire to the terminal Ax. | ||
* | * Using input-output module WBIO-DI-DR-8 (8 channels), see. [[Special: MyLanguage/Модули ввода-вывода | IO Modules ]]. One of the wires connected to GND, the second to terminal Dx of module. | ||
* | * Using extension module [[Special: MyLanguage/WBE-DI-DR-3|WBE-DI-DR-3]] (3 channels). One of the wires connected to GND, the second terminal of the Ox in the corresponding expansion module. | ||
* | * Can be connected to the inputs Rx controller, including internal current source. One of the wires connected to GND, the second to the Rx controller. | ||
Some counters have a pulse output to optocoupler, then two wires have the correct polarity - "plus" and "minus". | |||
In this case, minus connected to GND, and the "plus" to the input. | |||
Or "plus" to the power supply, negative to Ax (first method). | |||

And a controller '' 'to have a common ground' ''. | |||
There are several methods to connect these devices to the controller: | |||
* | * Using input-output module WBIO-DI-DR-8 (8 channels), see. [[Special: MyLanguage/Модули ввода-вывода|IO Modules ]]. The output "open collector" connect to terminal Dx module. | ||
* | * Using extension module [[Special: MyLanguage/WBE-DI-DR-3 |WBE-DI-DR-3]] (3 channels). The output "open collector" connect to terminal Ox corresponding extension module. | ||
* | * It can be connected to Rx inputs controller, activating the inside current. | ||

Use the extension module with relay outputs, eg[[Special:MyLanguage/Модули ввода-вывода#Модуль релейных выходов (WBIO-DO-R3A-8)|WBIO-DO-R3A-8]]. | |||
Connect the control contactor coil through the relay extension module (see. Figure). | |||
Expansion module contains TVS, protect the relay contacts from arcing. Exterior protective components is not required. | |||
== | == Connecting to the 1-Wire network == | ||
Ground connect to GND or common ground bus. | |||
The data line to 1-Wire terminal. | |||
The supply line to 5Vout terminal (internal power supply). | |||
It is allowed to use external power supply bus 1-Wire. | |||
When using a passive power supply pin of each sensor is connected to the earth wire. | |||
In this case, the bus consists two wires attached, respectively, to '1-Wire "and" GND ". | |||
== | == Connecting to RS-485 network == | ||
See [[Special:MyLanguage/RS-485|RS-485]]. | |||
Wiren Board 5 has two RS-485 port. The second port is multiplexed with the port CAN (L with A, H with B) | |||
Line A B is connected to terminals A and B respectively. Signal ground (if any) connected to the ground controller. | |||
If the RS-485 network is long enough, then it is recommended to use [[Wiren Board 5: Модуль расширения RS485-ISO|extension module with galvanically-isolated RS-485]]. | |||
