The high-speed HA Series controller is designed for applications requiring high accuracy and versatile functions and provides embedded Profibus or DeviceNet communications. The series includes a sampling rate of 0.025 seconds, or 40 times per second, which suppresses overshoot. The sampling function makes it suitable for extremely fast processes and mass flow processes in which measured values change rapidly. The HA Series panel mounted controller has a bright LED display for easy viewing. A maximum of two PID loops of control is provided in a single unit. Select from single loop, dual loop or cascade control modes. A multi-memory area stores up to 16 sets of parameters, allowing the unit to serve as a 32-segment ramp/soak controller. Optional functions include power feed forward and independent dual digital communication ports.
