3.1
LEDs
16 LEDs on the USB-OI16 (see Figure 1, p. 4), each dedicated to the inputs and outputs, are turned
on when a digital channel is high.
3.2
Connection to the PC
The standard USB connector (type B) serves for the connection of the USB-OI16 to the PC.
5V voltage supply is also provided via the USB interface.
3.3
Switching Voltage
A 7..32V DC switching voltage for the digital outputs can be connected at the 37-pin D-Sub female.
If there is no external power supply unit, a 5V power supply is generated internally for the outputs
1..16. The switching current per output in this case is 1mA.
