TRICONEX 2071H 7400313-100

Its main function is to safely and reliably read the switch signals from field devices (such as emergency stop buttons, pressure switches, liquid level switches, valve position feedback, etc.) into the Triconex safety controller.

Key Features and Functions
High Reliability and Safety:

Triple Module Redundancy: This is the core of the Triconex system. Each 2071H module actually contains three independent input circuits. Three independent processors read the signals from these 16 channels and perform a “two out of three” vote. A status is considered valid only when at least two processors read the same signal. This significantly eliminates single points of failure and ensures safe system operation even in the event of a hardware failure.

Fail-Safe Design: The module features comprehensive diagnostic capabilities. When an internal fault is detected (such as a channel failure, power supply failure, or processor communication failure), the module enters a predefined, safe state and reports it to the main controller, ensuring the system can respond appropriately.

Electrical Specifications:

Input Type: Digital Input (Dry Contact or Active Signal).

Rated Voltage: 24V DC.

Number of Input Channels: 16.

Active High: When the input signal reaches the high threshold, the module identifies it as “ON” or “1.”

Diagnostics and Maintenance:

The module features powerful online diagnostic capabilities, enabling detection of short circuits, open circuits, and other faults in field wiring.

It supports online hot swapping: Modules can be removed and inserted for replacement or maintenance without interrupting system power or downtime. This is crucial for process industries requiring high availability.

Physical Design and Installation:

This module uses a European standard card-type design and is installed in a Triconex-specific rack or chassis.

The front of the module typically features LED indicators that display the status of each channel (normal, faulted, active, etc.) and the overall health of the module, facilitating quick diagnosis by field personnel.

Typical Applications
Due to its exceptional safety and reliability, the TRICONEX 2071H module is widely used in industries with stringent safety requirements, including:

Oil & Gas: Critical emergency shutdown systems in offshore drilling platforms, refineries, and oil pipelines.

Chemical & Petrochemical: Reactor overpressure protection, fire, and gas detection systems.

Power Industry: Turbine overspeed protection and boiler protection systems.

Other Process Industries:  Any emergency shutdown system or critical process control requiring safety integrity levels of SIL 2 or SIL 3.
