TRICON 3625C1 Analog Input Module

Description

Product Detail: TRICON 3625C1 Analog Input Module

Overview

The TRICON 3625C1 is a high-density Analog Input Module designed for the Triconex® TRICON v9, v10, and v11 safety-critical triple modular redundant (TMR) control systems. This module provides reliable, high-precision acquisition of analog signals (e.g., 4–20 mA, 0–5 VDC) from field sensors, enabling continuous monitoring of process variables such as pressure, temperature, flow, and level in critical applications. Engineered for maximum fault tolerance and SIL 3 (Safety Integrity Level) compliance, it is a core component in environments where operational safety and system availability are paramount.

Key Features & Benefits

• Triple Modular Redundancy (TMR): Employs three independent input channels per point for voting and diagnostics, ensuring continuous operation even with two-channel failures.

• High Accuracy & Resolution: Delivers precise analog-to-digital conversion (e.g., 16-bit resolution) for accurate process monitoring and control.

• Built-in Diagnostics: Continuously monitors for faults (open wire, short circuit, signal drift) and reports them to the main processor for immediate action.

• Hot Swap Capability: Supports online module replacement without system shutdown, minimizing downtime in critical processes.

• Wide Input Range: Configurable for voltage (0–5 VDC, 0–10 VDC) or current (4–20 mA, 0–20 mA) signals, with optional isolation.

• SIL 3 Certified: Meets IEC 61508 standards for functional safety in safety instrumented systems (SIS).
