PCI 16 channels photo isolator input / output adapter


Product Code:APCI 16 PHOTO
INTRODUCTION
The PCI 16 channels photo isolator input/output 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 16 channels photo isolator input/output adapter provides 16 photo couple digital input/output channels, which allow the input/output signals to be completely floated and prevent the ground loop.

The features of PCI 16 channels photo isolator input/output adapter are:

*  32 bits PCI bus with Plug and Play (PnP) features.
*  Support 16 photo couple input/output channels.
*  Allow the photo input/output signals to be completely floated and prevent the ground loops.
*   By using 4N33 photo couple chips.
*  1500V isolation voltage.
*  Maximum load voltage is 30V.
*  Maximum 80mA input current.
*  Voltage range from 0V to 30V, where 0 to 3V is OFF and 5V to 30V is ON.
*  Operating temperature range from 0 to 33C.
*  Relative humidity rage from 0 to 90%.

The package includes following item
*  SMARTLAB PCI bus 16 channels photo couple input/output adapter.
*  User's manual.
*  Warranty form.






HARDWARE INSTALLATIONN
Your PCI bus 16 channels photo isolator input/output 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.
Turn off all power to your computer and all peripheral devices before installing your 16 channels photo isolator input/output adapter.
2.
Remove the cover of the computer.
3.
Insert the 16 channels photo isolator input/output adapter into any available PCI slot. Make sure the adapter is firmly seated in the chosen slot.
4.
Replace the cover of the computer.
5.
Turn on the power of your computer, the PnP features will recognize the 16 channels photo isolator input/output adapter.

HARDWARE CONFIGURATION
Before you use the PCI 16 channels photo couple input/output adapter, Please check our technical web site http://www.smatlab.com. You must ensure that the I/O address after boot your computer. Observe the figure in the follows, the proper jumper settings for the 16 channels photo couple input/output adapter is described in the following.
3.1 Switch Settings

The switch is used to identify card number, default setting is card 15 , and there are two methods to set the card number:

•  PnP mode

Just plug in SMARTLAB PCI BUS 16 CHANNELS RELAY OUTPUT / 16 CHANNELS PHOTO ISOLATOR INPUT ADAPTER into PCI slot, the PCI BIOS will allocate I/O address to each adapter automatically and assign card number start from 0 to each adapter. You may set any card number at PnP mode, and you need use software tools to distinguish port id. Almost all of the operating systems run at PnP mode.

•  manual mode

Set card number by card identifier switch, the PCI BIOS will assign pre-allocated I/O address to each adapter. Please set different card number to each adapter (do not duplicate card number setting).

•  The card number starts from 0 to 15.


3.2 I/O Address 

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

Base Address + 0:

3.4  Loopback Diagnostic

To test your 16 channel photo isolator input/output card, we recommend you use loopback circuit shown in below. Where IA*+ means input channel+ and IA*- means input channel-, OA*+ means output channel+ and OA*- means output channel-. * means channel number. Please note that, if you use IA2+, you must connect its pair IA2- …,otherwise if may short the circuit.

In this experiment, if VCC larger than 10V, then it input HIGH to input channel, otherwise it input LOW; your program can get this digital signal easily. If no VCC voltage input, the output channel will be loopback to input channel, it means when output HIGH then input channel get HIGH, when output LOW then input channel get LOW.
