DIO-3232L-PE

Overview / Features

This product is a PCI Express bus-compliant interface board for input/output of digital signals. This product can input and output digital signals at 12 – 24VDC.DIO-3232L-PE features 32 opto-coupler isolated inputs (supporting current sink output) and 32 opto-coupler isolated open-collector outputs (current sink type). You can use all of the input signals as interrupt inputs. In addition, the digital filter function to prevent wrong recognition of input signals is provided and output transistor protection circuit (surge voltage protection and overcurrent protection).Windows/Linux device driver is supported with this product.

• Opto-coupler isolated input (supporting current sink output) and opto-coupler isolated open-collector output (current sink type)
  • DIO-3232L-PE has the opto-coupler isolated input 32ch (supporting current sink output) whose response speed is 200µsec and opto-coupler isolated open-collector output 32ch (current sink type). 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 immunity.
• You can use all of the input signals as interrupt request signals.
  • 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.
• 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 channels can be added a digital filter, and the setting can be performed by software.
• The output circuit, has a built-in Zener diode and the overcurrent protection circuit of the surge voltage protection.
  • 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. The output rating is max. 35VDC, 100mA per ch.
• Windows/Linux support device driver
  • Using the device driver API-TOOL 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.
