See section [[Модули_ввода-вывода/en#Activating the modules in the controller web interface|activating the module in the web interface of the controller]]. | |||
''' | controls like EXT'''x'''_DR('''1-16''') appear in Discrete I/O device, corresponding to the inputs of the module. Corresponding MQTT topics (read-only) look like: /devices/wb-gpio/controls/EXT'''x'''_DR'''y'''. | ||
== Connectivity == | |||
'''Sensors/counters with pulse outputs/buttons.''' | |||
Such devices form a signal by closing two wires that are suitable for them. Connect one wire to the GND terminal of the module. Connect the second wire to the Dx terminal. A current of less than 2 mA flows through the button. Some counters have a pulse output on the optocoupler, then the two wires have a polarity - "plus" and "minus". In this case, minus is connected to GND, plus to Dx. | |||
'''Devices with open collector output.''' | |||
Both device and controller must be connected to the common grounding bus. Connect the open collector output to the Dx terminal. | |||
The module inputs are galvanically isolated from the controller. Therefore, the ground GND of the module and the controller may be different. | |||

''' | '''Note that the GND terminals of the upper row are used to connect the devices to inputs 1 to 8, and the GND terminals of the lower row are used for inputs 9 to 16.''' | ||
