32 Channels. Galvanically Isolated. Monitor & Control.

Record and output digital signals electrically isolated. The USB-OI16 features two 16-bit ports with 16 digital inputs and outputs each. Besides that, up to 2 counters or incremental encoders can be connected at the first digital inputs. The integrated pulse time measurement function produces precise results especially in the low-frequency range.

16 Optocoupler Inputs. 16 Semiconductor Switches.

16 digital states in the 3..32V voltage range can be sampled and recorded. The 16 semiconductor switches of the USB-OI16 are realized with high-side drivers for voltages in the 5..32V range.


The state of the input and output lines is indicated by LEDs.

Count and Measure: Pulses. Frequency. Position. Period.

If for the acquisition of large quantities, speed measurement, or determination of position: These are only a few applications the two 32-bit counters (incremental decoders) of the USB-OI16 can be used for. The integrated pulse time measurement function produces precise results especially in the low-frequency range.

Get Connected.

The digital channels of the application-specific hardware (sensor, machine, etc.) are connected at a 37-pin D-Sub female.

Plug & Play.

The connection to the PC is realized via USB. The USB-OI16 provides all typical USB features (e.g. Plug&Play, Hot-Plug). Up to 127 devices can be connected and installed during operation.


The device is internally supplied with 5V provided by the USB interface. This reduces cabling efforts to a minimum and makes mobile measurements a lot easier. An external supply unit can be connected for higher output switching voltages at the digital outputs (7..32V).

Optimal for Windows.

The drivers and programming interface is optimized for 64Bit under Windows® 10/11. All software for installation and programming of the USB-OI16 is included free of charge.

NextView. Try for Free.

The DAQ system is supported by NextView, the software for data acquisition and analysis. A fully functional 14-day trial can be requested under So it is possible, to directly test the functionality of the device.

DIN Rail Mounting.

The optocoupler system is suitable for DIN rail mounting. A DIN rail carrier with bracket is already included with the delivery.
