4. Technical Description

The Relay Output Card PCI provides four parallel reed relay output ports. The ports are organized as 1, 2, 3, and 4.

4.1 Features

•32 SPST relays

•DB37 connectors

•Highly reliable 10 VA DIP reed relays used

•Multiple cards can reside in the same computer

•PCI 2.1 bus compliant

4.2 Reed Relays

Reed relays provide very high quality, long life, low power, dry contact switch closures. Reed relays are not suited for high-current applications, and can be destroyed by capacitive or inductive load switching. The relays are normally open, and they close when energized.

See Chapter 1 for relay specifications.

4.3 Software

The Relay Output Card PCI comes with the SeaI/O suite of Windows® drivers. SeaI/O provides a consistent and straightforward applications program interface (API), allowing the developer to concentrate on the details of the application as opposed to low-level driver development. Popular development environments, including Visual C++, Visual Basic, and Delphi, are supported for application development. SeaI/O includes a utility for configuring the driver parameters under Windows, further simplifying installation.

For DOS, QNX, Linux®, and other operating systems, please refer to the software included with your card.
