The CAL 3300 controller is designed to be easy to use, low-cost and reliable.
It features CAL’s Auto-Tune facility, which makes P.I.D. control simple as it can automatically select the optimum P.I.D. values. It also has CAL’s unique dAC function to minimise the overshoot problem associated with conventional P.I.D. control. All this is fitted into a compact 48mm x 24mm (32nd DIN) package.
