Device working principle
Block diagram
The figure below represents the principle of the USB 8 digital inputs module.
Isolation of the inputs
As shown on Figure 5.1. the digital inputs are isolated from the host computer
(the red line) via:
- Opto-coupler for the inputs
- DC-DC converter for the isolated GND (Iso. GND

Installation
- This device must be installed by qualified personnel;
- This device must not be installed directly outdoors;
- Installation consists of mounting the device, connecting USB and connecting sensors.
Mounting
DIN rail:
Wall mounting
Figure 6.2. Mounting the device to a DIN rail
Figure 6.3. The mounting feets for wall mounting can be removed if necessary
Connecting inputs
- The module is compatible only with NPN sensors!
- All digital inputs are designed to work with maximum 30 V DC input voltage! Applying voltages higher than 30 V DC may damage the device!
DI Leds mode selection
The digital inputs leds working mode is selected via the jumper “DI Leds”
shown below
- Low mode – the input led is on when the input level is low (0);
- High mode – the input led is on when the input level is high (1).
It is mandatory to select the DI Leds mode with the jumper. Without selecting (leaving the jumper unconnected), the module leds will not work properly!
USB connection
It is necessary to be used USB-A to USB-B type quality cable like this one:

Drivers installation
The device is based on MCP2200 chipset. The drivers are usually built in the operating system. However if the device is still not recognized, they must be installed from the bellow link: http://www.microchip.com/wwwproducts/en/MCP2200
Windows
After successful installation, the relay board will be shown as shown below.
Linux
In Linux usually the drivers are installed by default
Software

Software examples
Many software examples in different language platforms can be found on this
link. Please note since the MCP2200 is with 8 input/output lines, it is very
important all the 8 lines to be configured as inputs only!
Please note the device is not controlled via Virtual COM Port (Virtual Serial Port) although it may appear in the OS in such way! It is controlled via USB HID API or USB HID raw protocol!
