Overview / Features

This product is an USB2.0-compliant digital I/O unit used to provide a digital signal I/O function on a PC. This product can input and output digital signals at 12 - 24VDC. This product features 16 channels of Optocoupler isolated inputs (compatible with current sink output) and 16 channels of Optocoupler isolated open-collector outputs (current sink type). You can use 32 input signals as interrupt inputs. Equipped with the digital filter function to prevent wrong recognition of input signals and output transistor protection circuit (surge voltage protection and over current protection). As there is compatible with PCI bus-compatible board PIO-32/32L(PCI)H and PCI Express bus-compatible board DIO-3232L-PE in terms of connector shape and pin assignments.

• 32 channels of Optocoupler isolated inputs (compatible with current sink output) and 32 channels of Optocoupler isolated open-collector outputs (current sink type)

  • This product has the 32 channels of Optocoupler isolated inputs (compatible with current sink output) and the 32 channels of Optocoupler isolated open-collector outputs (current sink type) whose response speed is 200µsec. Supporting driver voltages of 12 - 24 VDC for I/O(The outside circuit power supply of 12-24VDC is necessary separately). Common terminal provided per 16 channels, it can support a different external power supply every common.
• USB HUB function

  • This product has the USB hub function. Max. 4 DIO-3232LX-USB can be used in 1 USB port of PC. When you use 4 or more DIO-3232LX-USB, you can do by connecting DIO-3232LX-USB to the another USB port of PC side. Also, you can connect the CONTEC's USB device other than DIO-3232LX-USB to the USB port of DIO-3232LX-USB.
• You can use 32 input signals as interrupt request signals

  • You can use 32 input signals as interrupt request signals and also disable or enable the interrupt in bit units and select the edge of the input signals, at which to generate an interrupt. This product 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 setting 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 8channels outputs for over-current protection. The output rating is max. 35VDC, 100mA per channel.
• Connectors are compatible with PCI/PCI Express bus-compatible board

  • As there is compatible with PIO-32/32L(PCI)H and DIO-3232L-PE in terms of connector shape and pin assignments, it is easy to migrate from the existing system.
• Windows compatible driver libraries are provided.

  • Using the driver library API-DIO(WDM) makes it possible to create applications of Windows. In addition, a diagnostic program by which the operations of hardware can be checked is provided. Using the dedicated library VI-DAQ makes it possible to make a LabVIEW application.
