Overview / Features

This product is a negative-common typed PCI bus-compliant interface board used to provide a digital signal Input function on a PC. This product can input digital signals at 12 - 24VDC. This product features 128 opto-coupler isolated inputs (compatible with current source output signals). You can use 16 input signals as interrupt inputs. Equipped with the digital filter function to prevent wrong recognition of input signals is provided. Windows/Linux driver is bundled with this product. Possible to be used as a data recording device for LabVIEW, with dedicated libraries.

• Opto-coupler isolated input (compatible with current source output signals)

  • This product has the opto-coupler isolated input 128 channels (compatible with current source output signals) whose response speed is 200µsec. Common terminal provided per 16channels, capable of supporting a different external power supply. Supporting driver voltages of 12 - 24 VDC for input
• Opto-coupler bus isolation

  • As the PC is isolated from the input interfaces by opto-couplers, this product has excellent noise performance.
• You can use 16 input signals as interrupt request signals.

  • You can use 16 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.
• Windows/Linux compatible driver libraries are attached.

  • Using the attached driver library API-PAC(W32) makes it possible to create applications of Windows/Linux. In addition, a diagnostic program by which the operations of hardware can be checked is provided.
• This product has a digital filter to prevent wrong recognition of input signals from carrying noise or a chattering.

  • 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.
• LabVIEW is supported by a plug-in of dedicated library VI-DAQ.

  • Using the dedicated library VI-DAQ makes it possible to make a LabVIEW application.
