The VULCANIC range of controllers covers the great majority of industry requirements. Following steps will help you to define the right controller.
1) define the desired control precision: if ± 5°C, choose an 'ON/OFF' controller ; for greater precision, consider a 'PID' appliance.
2) Know what kind of temperature input is used : PT100 - Thermocouple - Current - Voltage.
3) Know what kind of power supply device is to be driven, so as to choose the type of control output (usually called Output P/N.1):
- for a contactor, choose a controller with a 'relay' output
- for a power unit, choose a controller with a 'numeric' output
- for a device with an analogic input (eg : motorised valve) choose a controller with an 'Analogic' output.
4) Know what use will be made of the auxiliary outputs (usually called 'Output N°2 and N°3') : choose a 'Relay' output to drive an alarm, 'Current or Voltage' for a measurement repeater, and/or 'Cold' output
2 to drive an ON/OFF valve for a cooling system.
