Wiren Board 6: Dry contacts module (opto relay)(WBE2-DO-SSR-2)
</languages> 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 opto relays with one common contact.
Each channel has built-in protection against voltage surges when switching inductive load (TVS at 40V).

Configuration
Configuration of the web interface is carried out in the section Configs => Hardware Modules Configuration.
Select WBE2-DO-SSR-2: Dual Small Signal SSR 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.
