Cycling program to step / broken in the standard 48x96mm with extraction from the front. Analog input selectable: thermocouples J, K, S, R, thermal resistance PT100, NI100 and signals normalized V / I. 2 relays 8A (resistive load) and an output logic SSR 12V-30mA programmable for control, alarms in the band, in deviation and absolute. The ATR420 is the ideal tool to realize the simple cycles of cooking on ovens and monitor all the parameters of the process. E 'keyboard can display the execution time of the cycle, the proportion of command output and the step being executed. Some special functions ensure the efficiency of the system: expected end step (useful in cases where the plant fails to reach the desired temperature in the allotted time), recovery cycle in the event in case of power-off gradient can be set.
