ISA Expansion Cards

Industry Standard Architecture (ISA) is a common communication bus in industrial computing. All of our ISA cards are suitable for use in an ISA passive backplane, which provides similar expansion functionality to a motherboard, or directly for use with an Industrial Motherboard supporting the ISA standard.

Our comprehensive range of expansion cards is perfectly suited for integration into any Industrial or Embedded Computer. Impulse have a range of expansions cards in PCIe, PCI, ISA and PC/104 form factors for connectivity, control and data acquisition applications.

DAQ CARD BUYING GUIDE

National Instruments or Advantech?

Advantech has long been a mainstay in the DAQ card industry, but still for many it may come as a surprise that their DAQ cards more than stand up to the National Instruments offerings, include LabVIEW support as standard, and come in at a fraction of the price.

Here we do a comparison of a few of the most popular DAQ cards from National Instruments alongside the Advantech equivalent.

Showing 8 ISA Expansion Cards
OverviewThe PCL-841 is a special purpose communication module which offers connectivity of the Controller Area Network to your PC. With the built-in CAN controller, the PCL-841 provides bus arbitration and error detection with automatic transmission repeat function. The PCL-841 is designed with 2,500V DC electrical isolation which makes the board ideally suited for harsh industrial environments. Impulse ca...

CANBus ISA Card
2 Port Isolated CANBus ISA Card
  • Expansion: Any, ISA
  • Operating temperature: Standard
  • Bus: ISA
  • Protocol: CANBus
OverviewThe PCL-833 is a 3-axis quadrature encoder and counter add-on card for the ISA bus. This card lets your PC perform position monitoring for motion control systems. Each input includes a decoding circuit for incremental quadrature encoding. Inputs accept either single-ended or differential signals. Quadrature inputs works with or without an index, allowing linear or rotary encoder feedback. The PCL-833 has...

quadrature encoder ISA card
3-axis Quadrature Encoder and 2-channel Counter ISA Card
  • Expansion: Any, ISA
  • Bus: ISA
  • I/O type: Counter, Motion Control
From £332
OverviewThe 3093 ISA digital I/O interface card provides 32 optically isolated inputs and 32 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 (10 Watt maximum), dry contact switch closures. Reed relays are well suited for low current appli...

Isolated Digital Input Output Card
16 Isolated Digital Input/16 Reed Relay Output ISA Card (DIO-32B)
  • Expansion: Any, ISA
  • Bus: ISA
  • I/O type: Digital Input, Relay - Form C
OverviewThe 3094 ISA digital I/O interface provides 16 optically isolated inputs. The inputs protect the PC and other sensitive equipment from spikes and ground loop current that can be generated in industrial environments. The inputs on the 3094 are rated for 3-13V. For 10-30V inputs, order the 3094H. Sealevel's SeaI/O Classic software drivers and utilities make installation and operation easy using Wind...

Isolated Digital Input Output Card
8 Isolated Digital Input/8 Reed Relay Output ISA Card (DIO-16)
  • Expansion: Any, ISA
  • Bus: ISA
  • I/O type: Digital Input, Relay - Form A ...
OverviewThe 3095 ISA digital I/O interface provides 16 reed relay outputs provide high quality, long life, low current (10 Watt maximum), dry contact switch closures. Reed relays are well suited for low current applications. The relays are normally open, and close when energized. Writing a "1" to the proper port bit can individually energize each relay. Sealevel's SeaI/O Classic software drivers an...

Reed Relay Output ISA Card
16 Reed Relay Output ISA Card (REL-16)
  • Expansion: Any, ISA
  • Bus: ISA
  • I/O type: Relay - Form A / Reed
OverviewThe 3098 ISA digital I/O interface relay output adapter provides four banks of eight switched Reed relays. The card’s DB-37 connector brings out the A-side of all relays while the optional B-side connector brings out the B-side and commons of all relays to a second DB-37 connector. This allows access to both sides of all 32 switches. The REL-32 can easily be configured as 32 independent relays, or ...
