UK Analog I/O Modules
Analog I/O Modules for Measurement and Control
Analog I/O modules measure sensor signals and drive actuators from a rugged embedded computer in vehicles, test rigs, unmanned systems and industrial machinery.
The range covers 16-bit analog input boards with up to 32 channels and autocalibration, 16-bit analog output boards with 4 to 16 channels, and a PCIe MiniCard that combines analog and digital I/O, all rated for -40 to +85 °C.
Boards fit PC/104, PC/104-Plus and Mini PCIe hosts; our guide to the PC/104 bus variants explains which fits which host.

An analog I/O module measures and drives voltages and currents from sensors, actuators and test equipment, alongside digital I/O. Channel count, resolution and input range usually decide the choice.
Channel Count
Count analog inputs and outputs separately, and allow spare channels for any sensors added later in the project.
Resolution and Sample Rate
16-bit converters are common. Check the sample rate per channel when several inputs are scanned together.
Input Ranges
Programmable ranges cover small sensor signals and larger control voltages. Confirm current loop support if you need it.
Automatic Calibration
Autocalibration on selected modules corrects drift over temperature without taking the system offline.
Digital I/O Alongside
Most modules add digital I/O lines, so one module can read sensors and switch relays or indicators.
Temperature Range
Modules are rated from -40 to 85 °C, which suits vehicles, aircraft and outdoor enclosures.
