Features
High Reliability:Based on the TMR architecture,three independent sub-circuits execute control tasks in parallel,using a”voting”mechanism to ensure data consistency,maintaining uninterrupted operation even in the event of hardware failures or transient interference.
High-Precision Output:Each channel features a self-calibration function to ensure signal output stability and accuracy.Fault Diagnosis and Maintenance:Output current is monitored in real time and fed back into the module,with signal accuracy verified through a loopback circuit.The fault diagnosis function detects channel anomalies,automatically deactivates the faulty channel,triggers an alarm,and supports online maintenance.
Application Areas
Industrial Process Control:This module can be used to regulate parameters such as temperature,pressure,and flow,and is suitable for production process monitoring in the chemical,petroleum,and power industries.
Safety System Integration:As part of a safety instrumented system(SIS),it ensures the safe operation of critical facilities such as nuclear power,transportation,and energy distribution.
Automated Production Lines:This module controls mechanical actuators,sensors,and other equipment to improve production efficiency and product quality.
