Overview / Features

This product is a PCI Express bus-compliant interface card that extends the digital signal Input functions of a PC. DI-32L-PE is a 12 - 24VDC opto-coupler isolated type with input 32ch. You can use all of the input signals as interrupt inputs. In addition, digital filter function to prevent wrong recognition of input signals is provided. Windows/Linux driver is bundled with this product.

• Opto-coupler isolated input (supporting current sink output) and opto-coupler isolated open-collector output (current sink type)

  • DI-32L-PE has the opto-coupler isolated input 32ch (supporting current sink output) whose response speed is 200μsec. Common terminal provided per 16ch, capable of supporting a different external power supply Supporting driver voltages of 12 - 24 VDC for I/O
• Opto-coupler bus isolation

  • As the PCI Express bus (PC) is isolated from the input and output interfaces by opto-couplers, this product has excellent noise performance.
• You can use all of the input signals as interrupt events.

  • You can use all of the input signals as interrupt events and also disable or enable the interrupt in bit units and select the interrupt edge.
• 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 input signals from carrying noise or a chattering.

  • This product has a digital filter to prevent 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 overcurrent protection circuit.

  • Zener diodes are connected to the output circuits to protect against surge voltages. Similarly, overcurrent protection circuits are fitted to each group of 8ch outputs.
