3. Key Features
3.1 Integrated Multifunctional Design
Combining 8 AI, 4 AO, 16 DIO, and 2 counter/timer channels eliminates the need for multiple single-function boards. This integration reduces PCIe slot usage, lowers system power consumption, and simplifies wiring—critical for compact embedded systems like portable test equipment and onboard controllers.
3.2 High-Precision Measurement & Control
16-bit analog channels deliver ±0.01% full-scale accuracy for AI measurements, ensuring precise capture of temperature, pressure, and flow variables. AO channels provide stable output with low noise (≤10 mVpp), enabling fine control of valves, motors, and other actuators in precision manufacturing.
3.3 SIL 2 Safety & Isolation
SIL 2 certification and built-in fault detection (e.g., AI open-circuit monitoring) ensure compliance with industrial safety standards. 2.5 kV DC isolation for analog channels prevents electrical interference, protecting the host system from voltage surges caused by faulty field devices.
3.4 Rugged Industrial Reliability
Engineered to withstand extreme temperatures (-40°C–85°C) and high vibration, the module operates reliably in harsh environments like oilfield monitoring and aerospace ground support. Industrial-grade components and rugged PCB design ensure a mean time between failures (MTBF) of over 500,000 hours.
