TRICONEX 3708E Isolated Thermocouple Module

Basic Overview

• Type: Analog input module, specifically an isolated thermocouple module.
• Series Affiliation: Belongs to the Triconex 3700 series of analog I/O modules.
• Purpose: Mainly used to collect temperature signals in industrial sites, convert the analog signals of thermocouples into digital signals, and provide reliable temperature measurement data for the Triconex Safety Instrumented System (SIS) to facilitate process control and safety protection.

Technical Features

• High Reliability: Adopts Triple Modular Redundancy (TMR) architecture. Even if a module fails, it can ensure continuous operation, guaranteeing the reliability and stability of the system, and meeting the SIL 3 safety level requirements.
• Multi-Channel Design: Equipped with 16 isolated differential thermocouple channels, which can collect data from multiple temperature points simultaneously, improving measurement efficiency and the overall performance of the system.
• Support for Multiple Thermocouple Types: Supports various types of thermocouples such as J, K, T, E, R, S, B, and C, which can adapt to different measurement environments and needs, providing users with flexible choices.
• High-Precision Measurement: The input impedance is 30MΩ (DC), with excellent noise suppression capability. The common-mode rejection ratio is at least -90dB at 0-60Hz, and at least -100dB at DC, ensuring measurement accuracy, with a precision of up to ±0.1% of full scale.
• Fast Response: The response time is only 50ms, which can quickly capture temperature changes, realize real-time monitoring and control of industrial processes, and promptly detect and handle potential safety hazards.
• Wide Operating Range: The operating temperature range is -40℃ to 85℃, and the humidity range is 0 to 95% non-condensing, which can adapt to various harsh industrial environments.

Application Fields

• Oil and Gas Industry: Used for temperature monitoring and control of facilities such as oil wells, pipelines, and refineries to ensure the safety and stability of the production process. For example, monitoring the temperature of oil well heads and oil pipelines to prevent safety accidents such as overheating and leakage.
• Chemical Industry: In the chemical production process, it accurately measures and controls the temperature of equipment such as reactors, distillation towers, and storage tanks to ensure the normal operation of chemical production and avoid dangers such as out-of-control chemical reactions and explosions caused by abnormal temperatures.
• Power Industry: Suitable for places such as power plants (thermal power plants, nuclear power plants, hydropower plants) and substations. It monitors the temperature of equipment such as generators, transformers, and switch cabinets, promptly detects faults such as equipment overheating, and ensures the safe and reliable operation of the power system.
• Metallurgical Industry: In processes such as steel smelting and non-ferrous metal smelting, it is used to monitor the temperature of equipment such as furnaces, heating furnaces, and rolling mills, optimize production processes, improve product quality, and prevent equipment damage due to overheating.
• Pharmaceutical Industry: Used for temperature monitoring in the pharmaceutical process, such as controlling the reaction temperature, drying temperature, and storage temperature during drug production, to ensure that drug quality meets standards.
