ATR421

Process controller/Programmer  15 cycles / 45 steps

Process controller 48x96mm (1/8 Din), single loop. It enables the programming of 15 cycles/programs which might include anything up to 45 steps/segments, all free selectable by the operator as rising/dwell/cooling steps. Distinctive feature is the extremely user-friendly programming, easy to handle even for the unskilled operator.

This programmer is specifically conceived for the automation of industrial kilns/environmental chambers/dryers and for the monitoring of thermal processes requiring the programming of cycles/profiles with control of process variables versus time. Special functions like Waiting (useful whenever the process has a delay on the programmed setpoint) and Cycle Recovery (after unexpected power failures) are included.

Universal analogue input, outputs selectable as command/alarm/auxiliary, analogue retransmission, serial communication RS485-ModbusRTU.  All options are configurable by keyboard, not requiring any jumpers selection. Useful extended supply range 24...230 Volt ac/dc, galvanically isolated, also between input/outputs.

Programming tools for quick set-up (MEMORY-CARD, programming and monitoring software LABSOFTVIEW).
