The temperature regulator with absolutely easy adjustment. Reliable, long lasting, exact: Digital-electronic. The regulator R 1120 was also developed as a replacement type for »S+B Schuntermann & Benninghoven« or »Elstein« or »Dr. Krieger« -regulator QDR-2.
  • Advantages / Advantages:
  • Adjustment of the process temperature avec bouton de róglage - easiest way every seen!
  • Adjustment of the parameters by easy structured operating interface and turning knob.
  • Two aditional output relays for different alarm- and helping functions.
  • If you exchange the old »QDR-2« - no new wiring necessary.
  • Meme format que »QDR-2«: 96x96mm DIN.
  • Modern digital electronic, based on the type R 1100.
  • LED-displays for process-temperature and and set-temperatures, function indication with yellow LEDs.
  • Connection with plug for simpliest exchanging.
  • Regulator types: Relay-output or output for SSR-relay available.
  • Pt100, NiCr-Ni (type K), Fe-CuNi (type L or J), °C or °F programmable
  • PI/D programable; automatic self adjustment gives a safe and secure regulating process of nearly every controlled section.
  • Made in Germany - 2 years warranty.
A little film on YouTube - how to start setup / installing the regulator R1120
Detailles techniques générales - R 1120:
Function types programmable:
Two-point regulator (heating - off or cooling - off)
Two-point regulator (cooling mode with non-linear cooling)
Three-point regulator (heating - off - cooling)
Three-point regulator (heating - off - cooling cooling mode with non-linear cooling)
Three-point step regulator (on request)
Sensor configuration programmable:
Pt 100, 0,0...99,9°C
Pt 100, 32...212°F
Pt 100, -100...+200°C
Pt 100, -148...+392°F
Pt 100, 0...400°C (factory setting)
Pt 100, 32...752°F
Pt 100, 0...800°C
T/C Fe-CuNi (L), 0...400°C
T/C Fe-CuNi (L), 32...752°F
T/C Fe-CuNi (L), 0...800°C
T/C Fe-CuNi (J), 0...800°C
T/C NiCr-Ni (K), 0... 999°C

Lower setpoint limitation programmable
Higher setpoint limitation programmable
Process-offset programmable
Adjustment lock: (different levels of locking programmable)
Alarm 2 and Alarm 3 -configuaration programmable:
no Alarm
Signal contact (off - on) (relatively)
Limit contact (off - on) (absolutely)
Limit range contact (comparator) (off - on - off) (relative)
Signal contact (on - off) (relatively)
Limit contact (on - off) (absolutely)
Limit range contact (comparator) (on - off - on) (relatively)
Limit range contact with start up suppression (off - on - off) (relatively)
Self opitmizing programmable:
no self optimizing
one time self optimizing on request to the control process
self optimizing automatically every time the regulator is switched on, if the difference between set point and process temperature value is larger than 7% of the measuring range.

Advice: In case of sensor- or connecting failures, the regulator and the alarms will respond similar to a range overflow (see manual).
The alarm contacts therefore do not offer protection against all types of plant breakdown With this in mind, we recommend the use of a second, independent temperature limiter.
