Product Description The DIO-32.PCIe digital I/O interface provides 1 6 optically isolated inputs and 1 6 reed relay outputs. The inputs protect the PC and other sensitive equipment from spikes and ground loop current that can be generated in industrial environments, while the outputs provide high quality, long life, low current (1 0 Watt maximum), dry contact switch closures. Reed relays are well suited for low current applications. The relays are normally open, and close when energized. The SeaI/O Classic software drivers and utilities can be obtained from the Sealevel web site. They make installation...

Depending upon your application, you are likely to find one or more of the following items useful with the 8004e. All items can be purchased from our website (www.sealevel.com) by calling our sales team at (864) 843-4343. cables DB37 Terminal Block (Item# TB02) Break out serial and digital connectors to screw terminals for easy field connection. The TB02 terminal block is designed with both DB37 male and female connectors for interfacing the inputs or outputs.

Electrical Specifications features • 2 sets SPST relays with each having 8 relays • 2 eight bit input ports • DB-37 Male connector for relay outputs • DB-37 Female connector for optically isolated inputs • Highly reliable 10 VA reed relays • Multiple adapters can reside in same computer input ports Contact Max Power Rating

manufacturing All Sealevel Systems Printed Circuit boards are built to UL 94V0 rating and are 1 00% electrically tested. These printed circuit boards are solder mask over bare copper or solder mask over tin nickel.

Hardware Installation Do not install the PCI Express board until the software has been successfully installed. The DIO-32.PCIe does not need to be configured prior to installation. Once you have installed the SeaI/O Classic software, install the board into an available PCI Express slot and boot the computer. The Found New Hardware wizard will appear. The drivers that were installed during the software installation process will automatically be used to configure the adapter. The following instructions are applicable to the Windows XP operating system and may vary depending on your version of Windows....

4. In right pane near the bottom, expand the ‘SeaI/O Device’ section by clicking the ‘+’ symbol. This shows the parent device is installed correctly. 5. You should see the card assignment listed as ‘SeaI/O 8004e’ with the card number in parentheses. The card number will increment for each additional SeaI/O device installed.

The DIO-32.PCIe provides four parallel input/output (I/O) ports. The ports are organized as ports A, B, C, and D. Port A and B are input ports interfaced to optically-isolated inputs, while ports C and D are reed relay output ports. Assuming an I/O address of 4000 Hex the following table shows the Port Addresses.

Programming the DIO-32.PCI Sealevel’s SeaI/O Classic software is provided to assist in the development of reliable applications for the Sealevel Systems family of PCI and PCI Express digital I/O adapters. The SeaI/O Classic software is included on the CD that shipped with the board. The software contains driver functions for use in accessing the I/O as well as helpful samples and utilities. PROGRAMMING FOR WINDOWS The SeaI/O Classic API (Application Programmer Interface) provides a variety of useful high-level function calls implemented in a Windows dynamic link library (DLL). The API is defined...

resistor, and must also not overdrive the opto-isolator input current specification. The following formulas apply: Turn on Voltage = diode drop + (turn on current) x (resistance) [Ex: 1.1 + (.003) x R] Input Current = ((input voltage)-1.1V) / (resistor value) Maximum voltage = 1.1 + square root of (.25(resistor value))

The following table shows common input resistors and the ranges associated with each. The turn-off voltage for all resistors is less than IV. The opto-couplers require a minimum voltage to turn on and this voltage is dependent on the input resistor shown on the table above. Increasing the input resistor accordingly can increase the maximum input voltage. Because socketed DIP resistors are utilized, they can easily be replaced with a different value. Sealevel can do this, if necessary. The input circuits are not intended for monitoring 120-volt AC circuits. In addition to being too high a voltage...

Inputs are interfaced via the DB-37 female connector on the supplied CA1 65 cable. OThe CA1 65 cable input pin out is not compatible with the 3093 ISA digital I/O board. If you are upgrading from the 3093 and wish to preserve existing infrastructure wiring, order the CA378 cable.

Reed relays provide very high quality, long life, low current (1 0 Watt maximum), dry contact switch closures. Reed relays are not suited for high current applications, and can be destroyed by inductive load switching, where a spark occurs across the contacts internally. The relays are normally open, and close when energized. output ports creed relay) pin assignments cdb-37 male) Outputs are interfaced via the DB-37 male connector on the supplied CA165 cable.
