View source for Модуль выходов "сухой контакт" (оптореле) WBE-DO-SSR-2/en

<languages/>
The module is designed to control the inputs of the "dry contact" type in applications where galvanic isolation is required.[[Файл:OPtRel.png|200px|thumb|right|Output contact diagram]]


==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).

==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.
