This series of "universal" controllers can be used with different types of temperature probes (NTC, PT100, thermocouples), including a version that can also manage an optional second NTC probe, enabling compensation operation (cooling or heating) or differential operation (difference between the two temperatures). They feature one digital input (two in the DIN rail version) that can be configured to manage functions such as an immediate or delayed external alarm, remote ON/OFF, etc. Programming is made extremely simple by the 9 selectable operating modes (e.g.: direct, reverse, dead zone, PWM, etc.).
A low consumption switching power supply is used.Moreover these instruments can be connected to any transducer able to supply a current (0 to 20 mA or 4 to 20 mA) or voltage signal (0 to 1 Vdc) for the measurement and control of physical values such as the pressure, humidity, etc.The models with voltage inputs, using the additional CONV0/1 module, can also accept transducers with a 0 to 10 Vdc output signal. They feature one digital input (two in the DIN rail version) that can be configured to manage functions such as an immediate or delayed external alarm, remote ON/OFF, etc.
