WBIO-DO-R10A-8

Purpose

Control of lighting, motors, contactors.

Technical specifications

Contains 8 HF32F-G relays (Datasheet) with SPST contacts configuration (two contacts per relay: NO/COM) switching the corresponding 8 outputs. The outputs are output to screw clamps designed for a maximum current of 20 A.

Permissible current up to 7A per channel. The module has protection against sparking of the contacts.

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.
