Analog Input Modules

The Triconex 3721 is a high-performance analog input module designed for use in industrial automation and process control systems. It is part of the Triconex family of safety instrumented systems (SIS) offered by Emerson. The 3721 module is specifically designed to provide reliable and accurate measurement of analog signals, such as temperature, pressure, and flow.

Features:

• TMR (Triple Modular Redundancy): Provides high availability and fault tolerance.
• Hot swappable: Allows for online replacement of a faulty module without interrupting system operation.
• Differential input: Reduces the effects of common-mode noise.
• High accuracy: Ensures precise measurement of analog signals.
• Low noise: Minimizes the impact of electrical noise on the measurement.
• Multiple input ranges: Accommodates a variety of sensor types.
• Diagnostics: Provides built-in diagnostics for easy troubleshooting.
• Safety certified: Meets the requirements of various safety standards.

Technical Specifications:

1. Number of channels: Typically 4 or 8 channels per module.
2. Input types: Differential, single-ended.
3. Input ranges: Various ranges available to accommodate different sensor types (e.g., 0-5V, -5 to +5V).
4. Resolution: High resolution for precise measurements.
5. Accuracy: Typically within 0.1% of full scale.
6. Sampling rate: Configurable sampling rate to meet application requirements.
7. Communication: Connects to the Triconex system via a high-speed serial bus.
8. Power requirements: Specified in the module's datasheet.
9. Environmental conditions: Operating temperature range, humidity, and other environmental factors.
