Triconex 3723X Analog Input Module | 32‑Channel HART AI Module for Tricon CX SIS System

Description

Product Overview

Triconex 3723X is a 32‑channel analog input module with HART pass‑through for Tricon CX SIS safety instrumented system. Built‑in TMR triple modular redundancy voting architecture, it acquires 4‑20mA analog signals from field transmitters and supports HART transparent communication. Comprehensive channel diagnostics detect open‑circuit, over‑range faults. This module is only compatible with Tricon CX I/O expansion chassis. OEM production is obsolete. New surplus stock and fully‑tested refurbished spare parts are available for direct drop‑in replacement for legacy SIS ESD safety systems in petrochemical, oil‑gas and power industries。

Technical Specifications

Key Features

1. Dedicated 32‑channel AI analog input module for Tricon CX system, native HART pass‑through to access smart transmitter HART parameters.
2. TMR triple modular redundancy voting architecture with SIL3 safety rating, single‑channel fault will not trigger system shutdown for critical process safety.
3. Full‑channel hardware self‑diagnosis for open‑circuit, short‑circuit and over‑range alarm, front‑panel LED for fast fault location.
4. Channel‑to‑channel galvanic isolation with strong anti‑interference performance for harsh electromagnetic cabinet environment of chemical and oil‑gas plant.
5. Hot‑swappable module design, online replacement without system shutdown, minimizing plant maintenance downtime.
6. Obsolete critical SIS automation spare part, widely used for legacy Tricon CX safety instrumented system repair.

Application

Petro‑chemical plant, oil & gas facilities, thermal power stations, Tricon CX SIS / ESD emergency shutdown system for analog transmitter signal acquisition and safety interlock protection.
