I/O boards, interface modules & custom embedded I/O
Embedded I/O forms the backbone of how your system interacts with the real world — from simple GPIO control signals to complex, high-speed data interfaces. Whether you need digital or analogue inputs, isolated industrial lines, or precise ADC/DAC conversion, the right I/O choice determines performance and reliability.
I/O design is often where embedded projects become challenging. Engineers must balance signal integrity, protocol compatibility, latency, ruggedness, and long-term availability – all while ensuring the system remains scalable and compliant with relevant standards.
Acal BFi supports engineers with a comprehensive range of industrial, high-speed, and specialist I/O solutions and the expertise to help you select, customise, or integrate the right technology into your design.
Wide range of embedded I/O products
If your design relies on serial buses like SPI, I²C, or UART, or industrial protocols such as CAN, Modbus, Profinet or EtherCAT, our portfolio covers the full range. We also support high-bandwidth interfaces including PCIe, USB, Ethernet up to 10 Gb, MIPI, and LVDS, as well as wireless options from BLE to cellular.
For scalable or modular designs, we offer PCIe cards, PXI cards and expansion options for SBCs and industrial systems. Whatever your application – from compact sensor nodes to rugged edge computers – selecting the right I/O is essential, and we’re here to help you identify the best fit.
Our offering spans standard interfaces, high-speed data channels, and ruggedised options ready for tough operating conditions. Engineers can browse our off-the-shelf solutions or speak with our specialists for guidance on selecting the right I/O for your design. If you are looking for specialised configurations please contact our Technology Centre to discuss options.
