8800 MiniTower Control Electronics The 8800 controller is a class-leading, fully digital dynamic controller that utilizes Instron® core technologies and is capable of running static and high-frequency dynamic tests. Found at the heart of Instron’s servohydraulic testing systems, the 8800 controller provides full system control, machine safety, transducer conditioning, and data acquisition, as well as acts as the foundation for the user interface to the testing machine. Features • Dedicated materials testing hardware and firmware-based controller developed through decades of research, development, and continuous use • Continuous synchronous data acquisition and loop closure rates of 10 kHz • Up to 24-bit data resolution across the entire span of each transducer provides maximum data quality • Automatic identification and calibration of all compatible transducers prevents configuration errors and simplifies setup • Specimen Protect function helps to avoid damage of specimen and fixtures during test setup and end of test • Continuous update of PID control terms with Adaptive Control - optimizes the control parameters throughout a test to suit the changing stiffness characteristics of the specimen • Expandable architecture; extensive analog and digital channel capabilities Console Software Console Software is the main user interface to the 8800 controller. Running on a PC, it allows all controller functions to be viewed and configured including control-loop optimization, setting of operational limits, and running of simple cyclic tests. Console provides the foundation for running more demanding tests in application software such as WaveMatrix™, Bluehill®, or specific software, such as the Low Cycle Fatigue or Fracture Mechanics suite. www.instron.com Handset and Frame Controls The handset, frame controls, and emergency stop button make up the hardware interface that is rigidly mounted to the testing machine. Their functionality includes switching the machine into low power or high power mode; offering fast or fine positioning of the actuator; and where fitted, opening and closing of hydraulic grips. Uniquely, the 8800MT offers additional protection by locking out the actuator and grip controls when a waveform is running, or when in load/strain control.
