DETAILED DESCRIPTION

ATR621
Programmer 72x72mm, single control loop. Allows the programming of 15 cycles/programs that can provide up to 45 steps/segments, all of which can be configured by the user as raise/maintain/lower. Programming mode of the work cycle that is intuitive and simple to use even for inexpert operators.
Step end wait software functions (in case of a delay of the process on the programmed setpoint value) and Cycle Recovery mode (after a power cut-off) are the main features of this programmer that has been specifically designed for the automation of industrial kilns, climatic chambers, dryers and the management of thermal processes in general that require the programming of cycles/curves with control of the process variable in relation to time.
Universal input and outputs that can be set as control, alarm/auxiliary and serial port RS485. All options can be configured from the keypad. MEMORY-CARD auxiliary support for the installer for quick configuration.
