This model is discontinued. Recommended replacement is WBIO-DI-WD-14 Buy WBIO-DI-WD-14 online
Purpose
Connection of pulse counters, buttons, switches, sensors with dry contact output.
Technical specifications
It contains 16 inputs for connection of dry contacts, united in two groups of 8 inputs with group galvanic isolation. The scheme of inputs is shown in the figure. The terminal is supplied with a voltage of 4.5 — 5.5 V, a small current flows to the ground (1-2 mA), causing the operation of the input.

Connection to controller
See section activating the module in the web interface of the controller. controls like EXTx_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/EXTx_DRy.
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.
