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. | 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. | |||

See [[Модули ввода-вывода/en#Activating the modules in the controller web interface|Activating the modules in the web interface of the controller]]. In the Module type field, select '''WBIO-DO-RxA-8: 8 Channel Relay I/O module'''. In the web interface the relay will be presented by the controls of EXT'''x'''_R3A1 — EXT'''x'''_R3A8 of the Discrete I/O devices. The corresponding MQTT-topics: /devices/wb-gpio/controls/EXT'''x'''_R3A'''y'''. | |||

== | == Load connection== | ||
Relays are connected in a phase break. | |||
