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.

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. Turn off all power to your computer and all peripheral devices before installing your 4 channels relay 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 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 isolator input adapter.
