Purpose

Connection of pulse counters, buttons, switches, sensors with dry contact output.

Technical specifications

It contains 14 inputs for connection of dry contacts, which are united in two groups of 7 inputs with group galvanic isolation. The scheme of inputs is shown in the figure. The terminal is supplied with ~ 4.5 V, when the small (1 mA) current is supplied to the ground, causing the operation of the input.

Connection to controller

See activating the module in the web interface of the controller.

Connection

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. 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.
