Product: TRICONEX 3382
TRICONEX 3382 Analog Input Module for Safety Instrumented Systems (SIS)
The TRICONEX 3382 is a high-reliability analog input module designed exclusively for TRICONEX safety instrumented systems (SIS) and triple modular redundant (TMR) control systems. Engineered to meet SIL 3 (Safety Integrity Level 3) certification standards, this module provides precise, real-time acquisition of 4-20mA analog signals from field sensors and transmitters. It features built-in fault detection, signal conditioning, and isolation to prevent cross-channel interference, ensuring accurate data transmission even in extreme industrial environments with high vibration, temperature fluctuations, and electromagnetic interference (EMI).
Core Functions:
  • High-precision acquisition of 4-20mA analog input signals (up to 16 channels)
  • Triple modular redundant (TMR) architecture for fault tolerance and continuous operation
  • Built-in signal isolation (channel-to-channel and channel-to-ground) to eliminate EMI interference
  • Real-time fault detection and diagnostic reporting for open/short circuits in input channels
  • Calibration-free operation with automatic self-test and drift compensation
  • Seamless integration with TRICONEX Tricon and Trident safety controllers
  • Compliance with IEC 61508 SIL 3 and OSHA process safety standards
