Module Description
The module is designed to control dry contact inputs and to switch low-voltage loads in applications where galvanic isolation is required.
The module contains two N-channel transistors with a common ground.
Each channel has built-in protection against voltage spikes when switching inductive loads (30V TVS).
The load ground (GND) must be connected to the GND terminal of the module (terminal O3 of the extension module).

Installation and Setup
When ordering modules in a bundle with a Wiren Board controller, we install them at the factory - you just need to configure the modules in the controller's web interface.
If you bought the modules separately, install them yourself:
- Disassemble the controller case.
- Insert the module, observing the polarity: the protrusion on it should fit into the slot on the controller board.
The module is compatible with all revisions of Wiren Board 6, Wiren Board 7, and Wiren Board 8. It can be installed as follows:
- Wiren Board 6.3–6.6 — up to 2 modules in the MOD1–MOD2 slots.
- Wiren Board 6.7–7.x — up to 3 modules in the MOD1–MOD3 slots. To install into MOD3, you must remove the interfering notch on the controller’s enclosure using pliers or a file.
- Wiren Board 8.4 — up to 3 modules in the MOD1–MOD3 slots.
- Wiren Board 8.5 — up to 4 modules in the MOD1–MOD4 slots.
Configuration
Change access level
To change the settings of the controller, you need the Administrator access level, which can be set in the Settings → Permissions section.
After completing the settings, we recommend that you set the access level to User or Operator - this will help you avoid making random mistakes when working with the web interface every day.
Доступно в релизе testing
To change the controller settings, your account must have the Administrator access level. Account management is available in Settings → Users. For more information, see User authentication and authorization.
Settings
After the module is physically connected, it must be added to the controller configuration:
- In the web interface, go to the section Settings → Configs → Hardware Modules Configuration, select the Internal slot where the module is installed extensions.
- In the Module type drop-down list, select the name of the installed module.
- Press the Save button. The controller will enable the ports required for the module to work.
To remove a module, select the type None.
Connection
The load is connected as follows: the positive terminal of the load is connected to the power supply, and the negative terminal is connected to the transistor output. To activate the load, a high signal must be applied to the transistor gate.
The illustrations show connection diagrams for an LED and a relay.
