MANUAL FOR PCI 4 CHANNEL RELAY OUTPUT / 4 PHOTO-ISOLATOR INPUT CARDS
PCI bus 4 channels relay output photo isolator input adapter
Product Code: PCI4PHOTO/RELAY
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.
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.
The package includes following
Check that your PCI bus 4 channels relay output/photo isolator input package includes the following items:
PCI bus 4 channels relay output/photo isolator input board.
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.Turn off all power to your computer and all peripheral devices before installing your 4 channels relay
Â output/photo isolator input adapter.
2.Remove the cover of the computer.
3.Insert the 4 channels relay output/photo isolator input adapter into any available PCI slot. Make sure the
Â 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 4 channels relay output/photo Â Â isolator input adapter.
Before you use the 4 channels relay output/ photo couple input adapter, you must ensure the I/O address. Observe the figure in the follows, the proper jumper settings for the 4 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:Relay output channel 1 to 4.
Base Address + 0:
isolator input channel 1 to 4.
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.
3. DB25 Connector Assignments
4. Terminal Board
When the SSR is built in the terminal board, then you can short JP5A and JP5B to control SSR1, JP6A and JP6B to control SSR2, Ketc.
The signal assignment of TB1, TB2, and TB3 are shown in the following:
