Double Setpoint Temperature Controller Pixsys Electronics ATR120

description

Double-setpoint controller, standard size 32x74mm. ON/OFF control (direct or reverse action for heating and cooling) or PI for thermocouples, RTD (ATR120-12AD) or linear signals 4...20mA, 0..10V (ATR120-22AD). Configurable measuring range -50/+999 °C/units. Two relays for control output and for programmable alarm (band, deviation, process). Error messages may be also visualized. Parameters are protected by password to avoid unauthorised access from the operator.

Controller ATR121 integrates and improves features and performances of this line.
