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.

''' | '''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. | |||
