Temperature Profiler - ATR620

Multifunction programmer/ step controller size 72x72mm. The ATR620 has been specifically developed as a control system for glass, ceramics, heat treatments kilns and furnaces.

Double display enables visualization of setpoint and process value, selected cycle, temperature at step end, output percentage, time elapsed from start, step in progress and power consumption/KWh. Fast advancement on cycle and manual control of output percentage to assure precise monitoring of the plant. If it is necessary to monitor two zones (example: kilns with extended chamber),  the “double loop” function is very useful to compare the reading of two sensors and keep uniform temperature inside the chamber. For each of the 15 programmable cycles, it is possible to program 20 steps/segments.

Special software functions provide high accuracy of firing profile for sensitive materials:
- Waiting function (useful when the plan cannot reach setpoint within the programmed time)
- Recovery function (with automatic or selectable gradient) in case of power failure.

Additional features include: 2 programmable digital inputs for Start/Stop/Alarm; operating as simple controller with programmable setpoint; starting setpoint; relay/SSR outputs for the management of heating groups, burners or auxiliary alarms; delaied start; Master/Slave mode for serial line (RS485+MODBUS-RTU protocol, up to 32 control loops).
