Product Short Description
Technical Specifications
- Channel Configuration
- It is equipped with 8 isolated thermocouple input channels for receiving signals from various standard thermocouples.
- It is configured with 1 isolated RTD reference junction compensation channel dedicated to terminal temperature sensing, which improves the accuracy of temperature signal collection.
- Signal Parameters
- It supports standard thermocouple types including B, E, J, K, N, R, S, T, and can also accept millivolt DC signals with an input range of -10.5 to +69.5 millivolts DC, which is equivalent to 0 to 64,000 raw counts.
- The millivolt input accuracy reaches ±0.03% of the span (±24 microvolts) at 25°C, and the RTD channel and thermocouple conformity both achieve an accuracy of ±0.25°C.
- It features thermocouple burnout detection, which triggers a full-scale indication when a burnout occurs to promptly alert to sensor faults.
- Electrical & Installation Specifications
- Each input channel is galvanically isolated from other channels and the ground, and can withstand 600 volts AC for one minute without damage, effectively resisting electromagnetic interference.
- It supports connection to a redundant 2 Mbps fieldbus, enabling automatic switching to the active path when one communication path fails.
- It is compatible with DIN rail-mounted and baseplate-mounted termination assemblies, allowing local or remote connection of on-site wiring and adapting to different installation layout requirements.
Description
Function Features
- High-precision Signal Processing
Each channel uses an independent sigma-delta converter for analog-to-digital signal conversion. The module also supports software-configurable integration periods, which can filter out power line frequency interference and processing noise. This combination ensures that the converted digital signals maintain high accuracy and stability, laying a foundation for precise industrial process control.
- Redundant Communication Protection
The module connects independently to a redundant fieldbus system. When the primary communication path malfunctions, the system can seamlessly switch to the standby path without interrupting data transmission. This redundant design greatly improves the reliability of the entire control system and avoids data loss or control lag caused by communication failures.
- Comprehensive Fault Monitoring
The integrated thermocouple burnout detection function sends a full-scale indication signal to the central control system once a thermocouple sensor burns out. This allows maintenance personnel to quickly detect sensor faults and carry out replacement and maintenance in a timely manner, preventing production accidents caused by inaccurate or lost temperature data.
- Easy System Integration & Maintenance
It follows the modular design concept of the I/A Series system and can be perfectly integrated with other Foxboro modules and components. It supports maintenance operations without removing on-site equipment termination cables, power supplies or communication wiring, which simplifies the maintenance process and shortens the system downtime caused by maintenance.
- Harsh Environment Adaptability
The module adopts a rugged structural design that meets the protection requirements of G3-class enclosures. It can resist the adverse effects of dust, temperature fluctuations and other harsh conditions on the industrial site, and maintain stable performance during long-term continuous operation, adapting to the complex and changeable operating environments of various industrial fields.
Application Scenarios
