Description
Spirax Sarco SX80 process controllers are 1/16 DIN panel mounted controllers for single and multiple set point control applications, for use with Spirax Sarco's range of pneumatically operated motorized control valves, electronic and electrical equipment. Each SX80 controller features VMD (3 point) and analog signal (4 - 20mA) outputs, and its quick-start code feature allows for easy field commissioning.
specificities
- Universal inputs - RTD, thermocouple, mA and mV.
- General Purpose Outputs - VMD (Valve Motor Drive), continuous mA and voltage, relays for on/off control and logic signals.
- Auxiliary Power - for external transmitters requiring 18VDC.
- Text Messages - can be set to scrolling text messages that can alert the user to the status of the process.
- Quick Code - 5-digit quick code for easy setup and debugging of the controller The controller can be easily installed and debugged.
