ATR621 is a single-loop PID Process controller, specifically designed for the automation of industrial ovens, climatic chambers, dryers and in general for the management of thermal processes, requiring the programming of cycles/profiles with control of the process variable in relation to time.
ATR621 allows the programming of 15 cycles/profiles with up to 45 steps/segments , all free programmable y the user as rising/dwell/cooling steps.
The cycle programming is simple and intuitive even for the inexperienced operator.
The instrument integrates software functions typically required in oven management: End-of-Step Wait (in case of process delay on the programmed setpoint) and Cycle Recovery mode (after any power failure).
All options are configurable from the keyboard.
Programming is facilitated by MEMORY-CARDS that allow all parameters and cycles to be quickly duplicated.
