TRICONEX 3624 Supervised Digital Output (SDO) Module

TRICONEX  3624  Supervised Digital Output (SDO) module

The TRICONEX 3624 Supervised Digital Output (SDO) module is a vital component of the Triconex Safety Instrumented System (SIS). Employing a Triple Modular Redundancy (TMR) architecture and complying with IEC 61508 and SIL 3 standards, it primarily delivers reliable digital output signals for safety-critical applications. The key details are as follows:

Features

• Robust Supervision Function: Equipped with built-in supervision, it continuously monitors output status and load, enabling timely fault detection and reporting to ensure the correctness and reliability of output signals.

• High Reliability: Adopting a redundant design with self-diagnosis capability, even if a single channel fails, other channels can operate normally to guarantee continuous system operation. The isolation design between modules further enhances reliability.

• Flexible Configuration: Supports multiple configuration modes to adapt to diverse application requirements and allows hot-swapping for convenient maintenance.

• Intuitive Status Display: The front panel is equipped with LED indicators to visually show the module status, facilitating easy monitoring by operators.

• 
  

Technical Parameters

• Output Type: Relay output.

• Output Voltage: 24VDC.

• Output Current: Maximum 0.7A per channel.

• Operating Temperature Range: -40°C to +70°C.

• Communication Interface: Supports Tribus protocol.

Application Fields

• Oil and Gas Industry: Used for monitoring and controlling equipment such as oil wells, pipelines, and storage tanks. It receives digital signals from controllers to drive valves, pumps, etc., ensuring safety protection for production processes (e.g., preventing fire, explosion, leakage, and other hazardous situations).

• Chemical Industry: Monitors and controls reactors, separators, and other equipment in chemical production. By driving relevant actuators, it realizes safety interlock functions, taking timely measures to safeguard production safety in case of abnormal conditions like reaction runaway or toxic gas leakage.

• Power Industry: Mainly applied in power plants and transmission lines to control circuit breakers, transformers, etc. It can quickly output signals for safety protection when power system failures (e.g., power outages, short circuits, overloads) occur, ensuring stable operation of the power system.

• Manufacturing Industry: Used for monitoring and controlling robots, production lines, logistics systems, etc. Through precise control of equipment start/stop, it achieves automated and safe production processes, improving production efficiency and product quality.

• Metallurgical Industry: Commonly used for safety control of equipment such as blast furnaces and converters. By driving actuators like motors and hydraulic systems, it ensures the safe operation of equipment in metallurgical production and prevents safety accidents caused by equipment failures.

• Pharmaceutical Industry: Controls key equipment and processes in pharmaceutical production to ensure compliance with strict quality and safety standards. It can promptly stop related equipment in case of abnormalities to avoid drug quality issues and safety accidents.
