Product Description


TRICONEX 3721C 32 - Channel Differential Analog Input Module
TMR - Based High - Precision Analog Acquisition for SIL 3 Safety Instrumented Systems
1. Module Core Overview
The TRICONEX 3721C is a TMR - designed 32 - channel differential analog input module, engineered for precise process variable measurement in SIL 3 (IEC 61508) safety - critical applications. It supports 0-5 VDC unipolar and - 5 to +5 VDC bipolar signals, with programmable 12/14 - bit resolution and ±0.15% FSR accuracy, ensuring reliable data acquisition for oil & gas, petrochemical, and power generation SIS.

Core Specs: 32 differential channels; 10 ms update rate; - 85 dB common - mode rejection (DC - 100 Hz); 24 V DC (20 - 32 V DC); ≤ 3 W; - 40°C to +70°C            • Key Features: TMR 3 - 2 - 1 voting; channel - level isolation; 150 VDC/115 VAC overrange protection; hot - swappable

2. TMR Redundancy & Measurement Precision
The 3721C integrates TMR signal processing with independent channel isolation, enabling 3 - 2 - 1 hardware voting to eliminate single - point failures. Its programmable 12/14 - bit resolution and ±0.15% FSR accuracy (0-60°C) deliver stable readings in harsh industrial environments, while - 85 dB common - mode rejection minimizes noise interference for critical process control.

TMR Architecture: Triple - modular redundant signal paths; independent diagnostics per channel; automatic fault isolation            • Precision Metrics: 12/14 - bit programmable resolution; ±0.15% FSR accuracy; 10 ms channel update rate            • Protection: 150 VDC/115 VAC input overrange protection; 500 VDC channel - to - backplane isolation

3. Chassis Compatibility & System Integration
The 3721C is fully compatible with Tricon v9/v10/v11 systems, seamlessly integrating with 8120E enhanced main chassis and 8111 expansion chassis via TriBus. It works with MP3009 main processors and 4351B communication modules, supporting up to 14 8111 expansion chassis for distributed I/O in large - scale SIS deployments.

Chassis Fit: 8120E main chassis (v11.x 1 Gbps TriBus); 8111 expansion chassis; hot - swappable in all Tricon chassis            • Software: TriStation 1131 v9/v10/v11 for configuration, diagnostics, and SOE event logging            • Expansion: Connects to 8111 via TriBus; supports remote I/O up to 12 km for distributed systems
