Operating principle

The module has 16 inputs for detecting the presence of AC mains voltage, with galvanic isolation by input group. The inputs are divided into two groups. The input activation voltage range is 110–260 V AC.

Installation

I/O modules connect to the right-hand side of a Wiren Board controller or a WB-MIO, WB-MIO-E or WB-MGE v.3 interface converter using the side connector. Make sure that every pin enters the corresponding socket. Secure the assembly on the DIN rail using end stops on both sides, but leave approximately 2 cm of free space to allow quick removal.

Up to eight modules can be connected in sequence: up to four input modules (type I) and up to four output modules (type O). The WBIO-AI-DV-12 is an exception: only one module of this model can be connected.

Addresses are assigned sequentially. Up to four modules can be connected in any order. For more than four modules, connect all modules of one type first, followed by all modules of the other type.

Wiring

The inputs are divided into two mutually isolated terminal groups:

(1, 2, 3, 4, 5, 6, 7, 8, N1) and (N2, 9, 10, 11, 12, 13, 14, 15, 16).

N1 and N2 are the common terminals for their respective input groups.

Configuration in the controller web interface

Configuration with a Wiren Board controller

After physically connecting the module, add it to the controller configuration:

In the web interface, open Settings → Configs.
Open Expansion modules and ports and select the WBIO module (External I/O module) slot corresponding to the connected WBIO side module.
In the Module type list, select the type of module installed.
Click Save.

WBIO modules do not support hot plugging.

To remove a module from the configuration, select Not installed.

Check that the external module is visible in the web interface:

Open Devices.
Find the Discrete I/O for digital modules, or ADCs for analog modules. Channel names follow the pattern EXTN_YYYY, where N is the module sequence number and YYY is the module channel name.

The MQTT topic address follows the pattern /devices/wb-gpio/controls/EXTN_YYYY.
