USB wiring is very sensitive against EMI errors (mainly sparking when opening contacts). The U-EMI-1 Kit is included with the DIN

rail version and includes two Würth folded cores for the USB data cable and a Ferrite sleeve for the power cable. If you are using

a HUB, it should be protected the connection HUB/computer (U-EMI-2)! The kit includes two Würth folded cores for the USB data

cable.

The cores must be mounted as shown in the illustrations, as close as possible on the connectors.

But also the avoidance of errors is very important. Therefore, the careful layout and installation of the wiring is very important!

Power Supply - TB5

The power-supply of our products must be 5V external DC. It is to pay attention to correct polarity. Otherwise, the product could be

damaged. If the board is by wrong power supply except function, you can try new store the firmware.

The U-EMI-1 Kit is included with the DIN rail version, and includes ferrite sleeve, shielded by EMI for the power cable. Are shown

on the image above.

For earlier versions of the Decision-USB IO was also the possibility of the power supply via the USB bus. To get greater stability,

this connection was removed. The USB bus power is not always able to provide enough power for the Relais switched on! The

result is a loss of connection or "hanging" USB module. An external power supply provides a secure power supply!

USB Power Management in Windows - In Window System, USB communication might disconnect under Power Saving Mode or

Sleep Mode. When connecting USB boards on PC, please make sure windows power management set in case interference with

USB communication.
