This USB2.0-compliant digital I/O unit provides a digital signal I/O function on a PC. This unit offers input and output digital signals at 12 - 24VDC. It features 16 optocoupler isolated input channels (compatible with current sink output) and 16 optocoupler isolated open-collector output channels (current sink type). You can use 16 input signals as interrupt inputs. Equipped with a digital filter to prevent wrong recognition of input signals and output transistor protection circuit (surge voltage protection and over current protection). The unit is compatible to a PIO-16/16L(PCI)H PCI bus-compatible board and DIO-1616L-PE PCI Express bus-compatible board in terms of connector shape and pin assignments.
16 optocoupler isolated input channels (compatible with current sink output) and 16 optocoupler isolated open-collector output channels (current sink type)
This product has 16 optocoupler isolated input channels (compatible with current sink output) and 16 optocoupler isolated open-collector output channels (current sink type) whose response speed is 200µsec. This unit supports driver voltages of 12 - 24 VDC for I/O (A 12-24VDC external circuit power supply is sold separately).
USB HUB function
This unit has a USB hub function. Max. 4 DIO-1616LX-USB can be used in 1 PC USB port. When you need to connect 4 or more DIO-1616LX-USB, you can do it by connecting DIO-1616LX-USB to another PC USB port on the side. Also, you can connect CONTEC's USB device different from DIO-1616LX-USB to the USB port of DIO-1616LX-USB.
You can use 16 input signals as interrupt request signals.
You can use 16 input signals as interrupt request signals: you can disable or enable the interrupt in bit units and select the edge of the input signals, at which to generate an interrupt. This unit has a digital filter to prevent wrong recognition of input signals from carrying noise or a chattering. All input terminals can be added a digital filter, and the configuration can be performed by software.
Output circuits include zener diodes for surge voltage protection and poly-switches for overcurrent protection.
Zener diodes are connected to the output circuits to protect against surge voltages. Similarly, polyswitches are fitted to each group of 8 output channel for over-current protection. The output rating is max. 35VDC, 100mA per channel.
Connectors are compatible with PCI/PCI Express bus-compatible board
The unit is compatible with PIO-16/16(PCI)H and DIO-1616L-PE in terms of connector shape and pin assignments, which makes it easy to migrate from the existing system.
Windows compatible driver libraries are attached.
Using the API-USBP(WDM) attached driver library makes it possible to create applications of Windows. In addition, a diagnostic program to check hardware operations is provided. Using the VI-DAQ dedicated library makes it possible to create a LabVIEW application.Specification
