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. 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. | Such devices form a signal by closing two wires that are suitable for them. Connect one wire to the GND terminal of the module.

Входы модуля гальванически развязаны от контроллера. Поэтому земли GND модуля и контроллера могут быть разными. | Входы модуля гальванически развязаны от контроллера. Поэтому земли GND модуля и контроллера могут быть разными. | ||
