The module is designed to control the inputs of the "dry contact" type in applications where galvanic isolation is required.
Technical specifications
The module contains two SPST (normally open) configuration optocouplers with one common contact.
Each channel has built-in protection against voltage surges when switching inductive load (TVS at 40V).
| Parameter | Value |
|---|---|
| Number of outputs | 2 |
| Outputs type | opto relay |
| Contacts configuration | SPST (normally open) |
| Maximum switching voltage | 40V AC/DC |
| Maximum switching current, per channel | 100 mA |
| The channel resistance in the open state | < 5 Оhm |
| Voltage isolation between the controller and the output | 1500 Vrms |
| Maximum power consumption | 0.05 Вт |
| Compatibility | Compatiblу with Wiren Board 5 of all revisions. |

| Terminal | Function |
|---|---|
| O1 | K1 |
| O2 | K2 |
| O3 | COM |
Configuration
Configuration is carried out in the web interface, section Configs => Hardware Modules Configuration.
Select "WBE-DO-OR-2: Dual Solid-State Signal Relay 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.
