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.

Connection to the controller
See 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 EXTx_R3A1 — EXTx_R3A8 of the Discrete I/O devices. The corresponding MQTT-topics: /devices/wb-gpio/controls/EXTx_R3Ay.
Load connection
Relays are connected in a phase break.
