INTRODUCTION

The PCI bus 4 channels relay output / photo isolator input adapter is a 32 bits PCI bus board with Plug and Play (PnP) features, it is a programmable I/O interface card for PC/486, Pentium, or compatibles. The PnP features let hardware configuration for IRQ and I/O address is detected by BIOS automatically, you don't need set switch and jumper.

The PCI bus 4 channels relay output / photo isolator input adapter provides relay output functions and photo isolator input functions. The relay output part provides 4 relays to drive 4 different output channels. Each relay channel can be used to control ON / OFF of external devices, to drive external high power relays, to activate alarms ... etc. The photo isolator input part provides 4 photo couple digital input channels, which allow the input signals to be completely floated and prevent the ground loop.

The PCI bus 4 channels relay output / photo isolator input adapter can be used to connect to terminal board, which provides relay output and photo couple digital input, and can be used to control SSR devices.

Please refer to Decision Industrial Interface (DII) software manual to know how to install the device driver for PCI Bus 4 Channel Relay Output Photo Isolator Input adapter, and how to write application program by using Active-X components.

The features of the PCI bus 4 channels relay output / 4 photo isolator input adapter are:

1. 32 bits PCI bus with Plug and Play (PnP) features.
2. Support 4 relay output channels and 4 photo couple input channels.
3. Max contact rating for relay: 120V AC/DC 1AMP.
4. Attraction time for relay: 3 ms.
5. Fall off time for relay: 2 ms.
6. Isolation resistance for relay: 100M OHM.
7. Life expectancy for relay: 100 million operations at signal level load.
8. Allow the photo input signals to be completely floated and prevent the ground loops.
9. Allow the photo input signals to be completely floated and prevent the ground loops.
10. Activation voltage: 0 to 30V or Switch.
11. Supports terminal board and control SSR.

The package includes following item

Check that your PCI bus 4 channels relay output/photo isolator input package includes the following items:

1. PCI bus 4 channels relay output/photo isolator input board.
2. PCI bus 4 channels relay output/photo isolator input terminal board (option).
3. Demo Program.
4. User manual.

HARDWARE INSTALLATION

Your PCI bus 4 channels relay output/photo isolator input adapter is designed to be inserted in any available PCI slot in your PC/486, Pentium or compatibles. In order to gain access to the expansion slots, follow the steps listed below:

1. I/O Address

The PnP feature will get base I/O address automatically, where

Base Address + 0:

Photo isolator input channel 1 to 4.

7	6	5	4	3	2	1	0
IN4	IN3	IN2	IN1

Jumper	Description
Open	Select Voltage Signal Input
Short	No Voltage Signal Input

The JP1A and JP1B are used to select voltage signal of photo input channel 1, and the JP2A and JP2B are used to select voltage signal of photo input cannel 2, ...etc. When we open both jumpers, it means the opto+ and opto- signals contains voltage; otherwise, when the jumpers are short, it means opto+ and opto- contain no voltage signal, it only represent ON/OFF connection point.
