Model TR122DA Temperature Relays for Pt 100-Sensors, 1 Sensor, Digital Display, 2 adjustable limits, 2 output relays, current output 0/4...20 mA WITH ANALOGUE OUTPUT (Code T224126)

Monitors the input signal for 2 limits. The TR 122 DA transduces the measured temperature/resistance to a proportional DC current.

Applications of the TR 122 D(A) are:
• Monitoring of temperatures with pre-alarm and alarm in machines and plants
• Controlling of temperatures e.g. for heated sample gas lines or refrigerating plants
• Transducer for Pt 100 (RTD) and resistance (TR 122 DA only)

Overview of Functions:
• 1 input sensor, Pt 100 (RTD) or resistance
• Measuring ranges -199...850°C / 0...850
Resolution 0,1 °C /
within the ranges -19,9...99,9 °C / 0-99,9

• 2 relay outputs (each 1 change-over contact)
• 1 analog output 0/4-20 mA scaleable (TR 122 DA only, not potentially separated from the inputs)
• Universal power supply AC/DC 24-240 V
• Storage and display of the measured MIN- and MAX-values
