USER'S MANUAL FOR PCI 8 CHANNEL RELAY OUTPUT
/ 8 PHOTO-ISOLATOR INPUT CARDS
PCI bus 8 channels relay / output photo isloator input adapter
Product Code: 8PCIPHOTO/RELAY
The PCI bus 8 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 8 channels relay output / photo isolator input adapter provides relay output functions and photo isolator input functions. The relay output part provides 8 relays to drive 8 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 8 photo couple digital input channels, which allow the input signals to be completely floated and prevent the ground loop.
Please refer Decision Industrial Interface (DII) Software manual to know how to install device driver for PCI bus 8 Port Channels Relay Output/ Photo Isolator Input adapter, and how to write application program by using Active-X Components.
features of the PCI bus 8 channels relay output / 8 photo isolator
input adapter are:
package includes following item
Check that your PCI bus 8 channels relay output/photo isolator input package includes the following items:
PCI bus 8 channels relay output/photo isolator input board.
Your PCI bus 8 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:
Before you use the 8 channels relay output/ photo couple input adapter, you must ensure that the I/O address. Observe the figure in the follows, the proper jumper settings for the 8 channels relay output/photo couple input adapter is described in the following.
1. I/O Address
The PnP feature will get base I/O address automatically, where
Base Address + 0:
channel 1 to
|Base Address + 0:
Photo isolator input channel 1 to 8.
2. Jumper Setting for 002 Board
The JP1 and JP2 are used to select voltage signal of photo input channel 1, and the JP3 and JP4 are used to select voltage signal of photo input cannel 2, …etc. When we open both jumpers, the input voltage from opto+ and opto- is range from 0 to 20V. Under this condition, 0 to 1.5V mean inactive and 3 to 20V represent active. In this mode, the hardware will isolate input signal and power. When the jumpers are short, it means 12V internal input will be provided from main board. Under this condition, no isolate is provided.
