When used in a machine or plant, is to ensure that after installation continues to the relevant
provisions, rules and guidelines are complied with!
These products come into contact voltage, therefore to consider the applicable VDE regulations

Security Note
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!

Ferrite sleeve on the power supply cable
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 rmware.
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.

When you need to connect more than 3 boards on one PC, please make sure the following below
1. Set different ID for each board.
2. Supply external 5V to each USB board.
3. Supply external 5V to USB hub.
Please make sure your external 5V power supply enough for the USB I/O boards. If input voltage is below 4.8V for USB I/O board,
it can’t work normally and sometimes it will cause device manager keeping refreshing itself or can’t recognize the device.

Schematic
Contact protection circuits
When a reed relay is used with an electromagnetic relay or solenoid, the energy stored will cause an inverse voltage when the
reed contacts break. The voltage, although dependent on the inductance value, sometimes reaches as high as several hundred
volts and becomes a major factor to deteriorate the contacts.
• DC: Protection circuit with a diode
• DC and AC: Protection circuit with Varistor or RC-element
The suppressor must be made to the load.
