3. Key Features
3.1 Integrated Multifunctional I/O
Combining 8 AI, 4 AO, 16 configurable DIO, and 2 counter/timer channels in one module, the TPMC871-10 eliminates the need for multiple single-function boards. This integration reduces system complexity, lowers power consumption, and saves PCIe slot space—critical for compact embedded systems like portable test equipment and onboard controllers.
3.2 High-Precision Measurement & Control
The 16-bit analog channels deliver ±0.01% full-scale accuracy for AI measurements, ensuring precise capture of process variables like temperature and pressure. The AO channels provide stable output signals with low noise (≤10 mVpp), enabling fine control of actuators such as valves and motors in precision manufacturing applications.
3.3 SIL 2 Safety Compliance & Isolation
Certified for SIL 2 operation, the module integrates built-in fault detection (e.g., open-circuit AI monitoring) and 2.5 kV DC galvanic isolation for analog channels. This design prevents electrical interference between the module and field devices, protects the host system from voltage surges, and ensures compliance with safety standards for industrial control systems.
3.4 Rugged & Reliable for Harsh Environments
Engineered to withstand extreme temperatures (-40°C–85°C) and high vibration, the TPMC871-10 is suitable for harsh operating conditions such as aerospace ground support, oilfield monitoring, and industrial factory floors. The rugged PCB design and industrial-grade components ensure long-term reliability with a mean time between failures (MTBF) of over 500,000 hours.
