This chapter provides information you should know before using the product.

About the Board

This product is a PCI bus-compliant interface board that extends the digital signal I/O functions of a PC.
DIO-0808L-PCI is a 12 - 24VDC opto-coupler isolated type with opto-coupler isolated input 8ch and
opto-coupler isolated open-collector output 8ch. You can use all of the input signals as interrupt inputs.
Equipped with the digital filter function and output transistor protection circuit (surge voltage protection
and overcurrent protection).
Windows driver is bundled with this product.

Features

- Opto-coupler isolated input (supporting current sink output) and opto-coupler isolated open-collector
output (current sink type)
DIO-0808L-PCI has the opto-coupler isolated input 8ch (supporting current sink output) whose response
speed is 200sec and opto-coupler isolated open-collector output 8ch (current sink type).
Common terminal provided per 8ch, 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 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 compatible driver libraries are attached.
Using the attached driver library API-PAC(W32) makes it possible to create applications of Windows.
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.
- Output circuits include zener diodes for surge voltage protection and fuses for overcurrent protection.
Zener diodes are connected to the output circuits to protect against surge voltages. Similarly, fuses are
fitted to each group of 8channels outputs for over-current protection. The output rating is max. 35VDC,
100mA per channel.
