FAQ
Q1: What does TMR mean in the 3701/55 system?
A1: TMR stands for Triple Modular Redundancy, where three processors simultaneously perform computations. The system votes among results to detect and isolate any fault, ensuring continued safe operation.
Q2: Can the ADAPT ESD be integrated with DCS or PLC systems?
A2: Yes. It supports standard communication protocols like Modbus TCP, allowing seamless integration with distributed control and safety systems.
Q3: Is the 3701/55 suitable for SIL 3 applications?
A3: Absolutely. The device is certified to SIL 3 under IEC 61508, making it suitable for high-integrity safety functions in turbomachinery control.
Q4: How many overspeed channels are supported?
A4: The system processes six speed input channels—two per CPU module—providing high-speed, redundant overspeed protection.
