Switching-Relays Typs TR 122 D(A) monitor 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
