Hardware Redundancy Design: Power Supply Module with high-availability (hot spare) redundancy design, supports dual electricity grid input; Control Net and System Net both applied dual high-available redundancy design; Controller Module dual redundancy with zero transition time, which ensures control consistency; System internal input voting algorithm, output voting algorithm, input/output self-diagnosis and error report mechanism for all digital and analog values, no user-programming necessity——redundancy design can simply be approached by configuring, and ensure efficiently and stably running.

  • Intrinsic safety IO modules:  Intrinsic safety type highway IO modules, save the security grid, save the installation space and the connection maintenance work;
  • Parts Intellectualized Design: I/O Modules, I/O Sub-Modules, Controller Module, Communication Modules all installed micro-controller-unites (MCUs) or multiple Processors, support Module self-diagnosis, fault-isolation, removal/insertion under power (RIUP) and on-process maintenance.
  • Intelligent conditioning, supports universal analog signal (voltage/current/TC/RTD) input, software selects signal types, full-scale high accuracy, self-correction and no further calibration or maintenance necessity.
  • Electro-Magnetic Compatibility(EMC) Design: All characteristics meet with related national standards as well as international standards: EN61000-4-2 (ESD) level 3, EN61000-4-3(RS) level 3, EN61000-4-4(EFT) level 3, EN61000-4-5(Surge) level 3, EN61000-4-6(CS) level 3 ---- Excellent Immunity against interference.
  • Low-power-consumption design, ventilation design based on natural circulation, thus no forced-cooling necessity and improves system adaptation to environment temperature.
  • Operation Safety Design: Multi-user authority zone security mechanism; data off-line-holding, redundancy status checking, fast-recovery, information security guaranteed.   
  • Strictly quality control & supervision on manufacturing process, parts high-temperature prefiring test for 72 hours, entire system comprehensively and continuously test for 120 hours; Obey ISO9001 International Standards thorough all working process, including system designing, developing, researching, manufacturing, service and so on.
