The module is designed to control dry contact inputs, as well as for switching low-voltage load.
Технические характеристики
The module contains two N-channel transistors with common ground.
Each channel has built-in protection against voltage surges when switching inductive load (TVS for 30V).
The ground (GND) of the load must be connected to the GND terminal of the module (O3 terminal of the extension module).
| Parameter | Value |
|---|---|
| Number of outputs | 2 |
| Output type | N-channel field effect transistor
(open collector) |
| Contact configuration | SPST (normally open) |
| Maximum switching voltage | 30V DC |
| Maximum switching current, per channel | 2A' |
| The channel resistance in the open state | 40 mOhm |
| Voltage isolation between the controller and the output | no |
| Maximum power consumption | 0.01 W |
| Compatibility | Compatible with Wiren Board 5 of all revisions.
Can be installed into both extension slots. |
Pinout
| Terminal | Function |
|---|---|
| O1 | K1 |
| O2 | K2 |
| O3 | GND |
Configuration
Configuration of the web interface is carried out in the section Configs => Hardware Modules Configuration.
Select "WBE-DO-OC-2: Dual Open-Collector Output Module" in the Internal slot 1 or 2 section (depending on the slot number) and click Save.
Once added, two additional outputs appear in the Devices next to the controller outputs (the Discrete I/O section).
When adding a device is detected immediately, a reboot is not required.

Порядок подключения
Нагрузка подключается следующим образом: "плюс" нагрузки подключается к источнику питания, "минус" подключается к транзисторному выходу. Чтобы нагрузка начала работать, нужно подать высокий уровень на затвор транзистора.
На иллюстрациях приведены схемы подключения светодиода и реле.
Технические детали
Сигналы управления реле находятся на контакте SDA (K1) и SCL (K2) модуля расширения
