Controller 48x96mm (1/8 DIN), Single/Double Control loop, characterised by high configurability of the inputs and outputs.

The two analogue inputs can be configured for a vast range of sensors with the option of controlling two distinct processes or managing mathematical operations (sum, difference, average) between the two processes. Power supply range from 24 to 230V AC/DC. Outputs can be selected as control, alarm, analogue retransmission. Useful power supply range from 24 to 230V AC/DC with galvanic isolation from the network, galvanic isolation between inputs and outputs and isolated serial RS485.

The PID hot-cold control algorithm can also be used on systems with cascading control (remote setpoint) through image input.

The functions of the ATR401 software include open-close logic for valve control, Soft-Start function with control of the climb gradient (degrees/hour), TA input with maximum current threshold alarm, external activation from digital input of programmable functions.
