TRICONEX 3351 Analog Input Module

Product Description:
The TRICONEX 3351 Analog Input Module is designed for high-reliability industrial safety and automation systems, especially for applications that demand SIL 3 (Safety Integrity Level 3) compliance. Utilizing Triple Modular Redundancy (TMR), the module is engineered to eliminate single points of failure in analog signal acquisition and transfer. It supports a wide range of input signals including current, voltage, thermocouple, and RTD, with advanced built-in features like filtering, linearization, and comprehensive diagnostics.​

Product Parameters and Specifications:

  • Input Channels: 8 independent differential analog inputs (each channel isolated)​

  • Supported Signal Types:

    • Current: 4–20 mA DC (nominal), 2–22 mA DC (operational)​

    • Voltage: 0–5 V DC, 0–10 V DC, ±5 V DC, ±10 V DC

    • TRICONEX 3351

    • Thermocouples: J, K, T, E, R, S, B, N types (optional)​

    • RTD: Pt100, Pt1000 (2/3/4-wire, optional)​
