Connection to the controller

See Activating the modules in the web interface of the controller. In the Discrete I/O device, EXT(1-8)_DIR(1-4) and EXT(1-8)_ON(1-4) controls will be created after the module connection. DIR controls are responsible for direction selection (relay R2 on the circuit), and ON controls are responsible for switching on and off (relay R1 on the circuit). These controls in MQTT messages are called /devices/wb-gpio/controls/EXTx_DIRy and /devices/wb-gpio/controls/EXTx_ONy.

Module outputs — load connection

The phase wire is connected to the Lx terminals. Both terminals of the Lx contact group are connected on the board. NC and NO terminals are connected to the engine, setting the direction of rotation. The NO and NC outputs are protected by varistors.
