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.

*) Maximum switching current is specified for 230 VAC resistive load.
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.
