2 Interfacing Examples
2.1 Connect Input Signal
Exemplarily, the connection of an input signal at pin 3 and 10 of the USB-PIO-OEM is illustrated. The 1k
resistor and the 100pF capacitor have protective and noise suppressive functions. For voltages higher than
5V a voltage divider is required (see calculation below chapter 2.3).
2.2 Connect LED, Relay to Digital Output
In the figure displayed above, pin 27 and 38 are set to output. At pin 27, the connection of an LED is shown.
At pin 38, a relay is controlled via a transistor.
Please also observe the total current listed in the technical data (see chapter 6).
2.3 Use Voltage Divider
If connecting a DC voltage higher than 5V, a voltage divider must be used so that 5V at the maximum are
applied at the device input. Exceeding the 5V input voltage might cause damages to the device. Due to
TTL/CMOS technology used, input voltages less than 5V are also sufficient (high 3V).
The relation of the resistors to be used can be calculated with the following formula:
U/U1= (R1+R2)/R1

5 Important Notes for Using the USB-PIO-OEM
 The device is only suitable for extra-low voltages - please observe the relevant regulations! Only use the device
with housing closed. ESD voltages at open lines may cause malfunction.
 Definition and test of the CE-standards to be applied must be made by the operator!
 Only use non-solvent detergents for cleaning. The product is designed to be maintenance-free.
 Signal cables are connected at the module pins – preferably use shielded cables. For best possible interference
suppression, connect shield at one end only. Close open inputs if necessary.
 The device ground and the chassis are electrically connected to the chassis of the PC, which is usually also
connected to ground. Be sure to avoid ground loops since they will cause measuring errors!
 PCs (notebooks) which are not grounded often produce high potentials to earth at the USB socket so that safe
operation cannot be guaranteed. In this case, connect the measuring system to earth.
 The device must not be used for safety-relevant tasks. With the use of the product, the customer becomes
manufacturer by law and is therefore fully responsible for the proper installation and use of the product. In the case
of improper use and/or unauthorized interference, our warranty ceases and any warranty claim is excluded.
Do not dispose of the product in the domestic waste or at any waste collection places. It has to be either duly
disposed according to the WEEE directive or can be returned to bmcm at your own expense.
