Page 3: Introduction
Introduction Overview The DIO-32.PCI digital I/O interface provides 16 optically isolated inputs and 16 reed relay outputs. The inputs (rated for 3-13V) 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 (10 Watt maximum), dry contact switch closures. -

/ removal of the software and information about latency, logic states, and device configuration. For C language programmers we recommend using the API to access the DIO-32.PCI. If you are programming in Visual Basic, using the ActiveX control included with SeaI/O is advised. - Page 8 PROGRAMMING THE DIO-32.PCI, CONTINUED Digital I/O Interface The DIO-32.PCI 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.
- Page 9 The turn-off voltage for all resistors is less than 1V. 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.
- Page 10 PROGRAMMING THE DIO-32.PCI, CONTINUED The CA165 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. Output Ports (Reed Relay) Reed relays provide very high quality, long life, low current (10 Watt maximum), dry contact switch closures.

- Page 12 The relay ports return the ones complement of the value that is currently being used to drive the relays. Writing the Outputs The output ports are the only ports that can be written. The relays on a standard DIO-32.PCI are normally open. To close a relay a one must be written to the appropriate bit.
