Overview / Features

This product is a PCI Express bus-compliant interface board for output of digital signals. This product can output digital signals at 12 - 24VDC. DO-32B-PE features 32 opto-coupler isolated open-collector outputs (current sink type). In addition, this product is equipped with a power supply for driving opto-couplers (12VDC) and output transistor protection circuit (surge voltage protection and overcurrent protection). Windows/Linux device driver is supported with this product.

• Opto-coupler isolated open-collector output (current sink type)

  • DO-32B-PE has the opto-coupler isolated open-collector output 16channels (current sink type) whose response speed is 200?sec. Common terminal provided per 16channels, capable of supporting a different external power supply. Supporting driver voltages of 12 - 24 VDC for I/O
• Opto-coupler bus isolation

  • As the PC is isolated from the input and output interfaces by opto-couplers, this product has excellent noise performance.
• Power for opto-coupler operation (12VDC 240mA) supplied internally

  • As the power(12VDC 240mA) to run the opto-couplers is supplied internally, no external power supply is required. The use of jumpers allows you to decide whether you want to use the internal or external power supply for every 16 points.
• 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.
• 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.
