Page 3: Introduction
Introduction The DIO-32.104 is a PC/104 form factor adapter that provides 16 reed relays that can switch power, data, or other electronic signals for control applications and 16 optically isolated inputs to allow monitoring of off board switch closures, relays or for any other general purpose monitoring needs. The inputs (rated for... -
Page 4: Before You Get Started
Before You Get Started What’s Included The DIO-32.104 is shipped with the following items. If any of these items are missing or damaged, please contact Sealevel for replacement. DIO-32.104 Adapter • Advisory Conventions Warning The highest level of importance used to stress a condition where damage could result to the product, or the user could suffer serious injury. - Page 5 40-Pin IDC to DB-37 Female 8” Ribbon Cable (Part Number CA211) The CA211 connects to the 40-pin header connector on the DIO-32.104 and provides a DB- 37 Female connector. The CA211 is typically used for the isolated input side of the DIO- 32.104.

Page 6: Card Setup
The DIO-32.104 contains several jumper straps for each port that must be set for proper operation. The DIO-32.104 occupies 4 consecutive I/O locations. The DIP-switch (S1) is used to set the base address for these locations. Be careful when selecting the base address as some selections conflict with existing PC ports. -

Page 10: Physical Installation
Physical Installation Extreme care should be taken when installing the DIO-32.104 to avoid causing damage to the connectors. After the adapter is installed, connect your I/O cables to the P1 (relays) and P2 (inputs) header connectors. Please note these headers are keyed so that pin 1 of the cable matches pin 1 of the connector. Refer to Card Setup for information on setting the address before inserting the DIO-32.104 onto the stack. -
Page 11: Programming The Dio-32.104
Digital I/O Interface The DIO-32.104 provides four parallel input/output (I/O) ports. The ports are organized as ports A, B, C, and D. Ports A and B are input ports interfaced to optically-isolated inputs, while ports C and D are reed relay output ports. - Page 12 16.9V 15mA 2.2KW 7.7V 7.7 – 20.0V 24.5V 10mA 3.3KW 10.0V 10.0 – 24.0V 30.0V 4.7KW 15.2V 15.2 – 28.0V 35.0V The turn-off voltage for all resistors is less than 1V. © Sealevel Systems, Inc. 3730H Manual | SL9020H 12/2022...
- Page 13 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, if necessary can do this. The input circuits are not intended for monitoring 120-volt AC circuits. In addition to being too high a voltage for the circuits, it is dangerous to have that high a voltage on the card.
- Page 14 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. © Sealevel Systems, Inc. 3730H Manual | SL9020H 12/2022...
- Page 15 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-32.104 are normally open. To close a relay a one must be written to the appropriate bit.
