PC/104 Peripheral Boards

PC104 Stack
PC/104 is an industry standard which defines a mechanical and electrical specification for rugged small form-factor computer systems. Boards follow a 3.6" x 3.8" size and connect together using a stack-together bus arrangement. Simply mix and match processor and peripheral hardware to meet your requirements. Advantages include accelerated time-to-market, lower development costs, design flexibility, multi-vendor support and the ability to use standard PC software. These important attributes have made PC/104 a long-established choice for demanding applications including Industrial Control, Military, Medical, and Aerospace.

DIO96-104

96-Bit Digital I/O

DIO96-104

Stock #100-7618

Applications requiring a large number of digital I/O will benefit from our DIO96-104. The board is based around the venerable 82C55A Peripheral Interface chip which provides three 8-bit bi-directional ports (24 digital I/O). The DIO96-104 uses four 82C55A chips for a total of 96 bits of digital I/O. Each chip is routed to its own 26-pin IDC header for easy system integration.

Key Features
  • Uses industry standard 82C55A chips
  • Supports Input, Output, and Strobed operations
  • Low power CMOS deign

RELAYIO-104

8 Relay Outputs, 8 Optically Isolated Inputs

relayio-104

Stock #100-7610

The RELAYIO-104 is an 8-bit digital I/O peripheral module offering electrical isolation between the host and externally connected devices. It conforms to the PC/104 standard and operates on a +5V only power. A single 40-pin I/O header is used for all external wiring.

Embedded applications often involve the controlling and sensing of various external AC and DC signals while also requiring electrical isolation for the host computer. External solid state relay racks or similar devices are often considered but can be too bulky in many situations. The RELAYIO-104 allows field signals to be brought to the PC/104 system. It has the flexibility to accept combinations of AC and DC signals and offers 500V host-to-field isolation.

Key Features
  • Eight SPDT (form-C) Relay Outputs
  • Eight oprically isolated AC/DC digital inputs
  • Input filters for AC and noisy signals
  • 500V isolation between PC/104 bus and I/O signals
