Purpose
Control of contactors, warning lights, etc.
Technical specifications
Contains 8 relays. Two of them are rocker (NO/COM/NC) switching corresponding 8 outputs. The outputs are output to screw clamps designed for a maximum current of 20 A.
Permissible current: up to 3A per channel.

Подключение к контроллеру
Смотрите раздел Активирование в веб-интерфейсе контроллера. В поле "Module type" следует выбрать устройство WBIO-DO-RxA-8: 8 Channel Relay I/O module. В веб-интерфейсе реле будут представлены контролами EXTx_R3A1 — EXTx_R3A8 устройства Discrete I/O. Соответствующие MQTT-топики: /devices/wb-gpio/controls/EXTx_R3Ay.
Подключение нагрузки
Реле подключаются в разрыв фазы.
