2-step temperature reglulator with integr. fault warning system - MPR-SM..

Temperature regulator with built-in fault indicator with 10 fault input ports. Housing front 96 x 96 mm

For controlling heating and refrigeration operations in technical systems, with simultaneous monitoring of functions.

Multiple programming options.

Can be ordered with 1-3 switching contacts to control compressors, heaters, alarms etc.

 

Temperature regulator unit:

  • Easy operation via three work levels
  • Automatic parameter storage without data loss when a power-cut occurs
  • Target temperature and upper/lower hysteresis limit freely adjustable
  • Lockable buttons to prevent changes to target temperature
  • Alarm in the event of sensor short-circuit/sensor fault (adjustable relay switching state in event of fault)
  • Separately adjustable minimum action time and minimum pause time for output relay
