Temperature Module TEMP-02U

With the flush-mounted Temperature Module TEMP-02U two Temperature Sensors can be read in.

Quick Facts

  • 2 Temperature sensor connections
  • Temperature monitoring
  • Outdoor temperature measurement
  • Room temperature measurement

The Temperature Module is used to read in 2 temperatures using the separately available digital Temperature Sensor TF-xx. These values can be further processed in the Master Module, so that temperature-dependent control and regulation can be implemented. Application areas for this are: Control cabinet temperature monitoring, outdoor temperature measurement, room temperature measurement...

Measuring ranges

Like the analog value of an analog input module, the temperatures are transferred to flags with the TRFAD command. Input AE1 corresponds to sensor 1 and input AE2 to sensor 2. In addition, the digital inputs of the temperature module can be read. Bits 1 and 2 indicate the readiness messages (E1 = 1: sensor 1 ready, E2 = 1: sensor 2 ready) of the sensors.

These bits are only set to 1 if a functional sensor is connected to the corresponding input.

Inputs 3 and 4 (E3 for sensor 1 and E4 for sensor 2) indicate the negative sign of the probe temperatures. The sign bit of a sensor is set when the measured temperature at the sensor is less than 0°C, regardless of the measuring range with which the sensor is configured.

Note: The sign of the sensor temperature can be read at the digital inputs E3 (sensor 1) and E4 (sensor 2).
