Pt 100-Temperature-Relay Type TR122DA
1 Sensor, 2 Limits, Digital display, Analog-output

The TR122DA is a temperature relay with 2 independant switching points and with analog output.

APPLICATIONs:
• Monitoring of temperature with
   pre-alarm and alarm
• Monitoring of under- and over-temperature
• 2-point-controller, e.g. for heating (the second 
   switching point can be used for monitoring the function
   and release an alarm at over- or undertemperature)
• 3-point-controller for heating/keeping temperature
• Monitoring of resistance 0...850 Ohm
• Transducer for Resistance
