Key Features

• Triple Modular Redundancy (TMR): Ensures fault tolerance by triplicating critical components. If one channel fails, the remaining two continue operation, achieving an MTBF exceeding 200,000 hours.
• High Precision and Stability: Provides precise analog outputs for fine-grained process control, reducing process variability and improving product quality.
• Fail-Safe Design and Advanced Diagnostics: Monitors output signals, voltage, and temperature in real-time, switching to a safe state within 10 ms in case of a fault.
• Rugged Environmental Performance: Operates reliably in extreme temperatures and harsh industrial settings, such as offshore platforms and refineries.

Applications

• Oil and Gas: Controls valve positioning in subsea pipelines, regulates compressor speed in refineries, and manages emergency shutdown (ESD) systems.
• Chemical Processing: Precise control of reactor temperatures, agitator speeds, and material feed rates in batch and continuous processes.
• Power Generation: Adjusts fuel flow to gas turbines, controls steam valve positions in boilers, and manages grid synchronization in power plants.
