Description

Measured parameters

Analog Input, 0...20 mA / 4...20 mA (RMS-MADC-XXX-A) or 0...10 V (RMS-MADC-XXX-V)

Accuracy

(humidity & temperature)

Temperature: ±0.5 °C @ 25 °C / ±1 °C @ 0…70 °C / ±3.5 °C @ other temperature range

Relative humidity: ± 3 %rh @ 25 °C

Dimensions

83 x 29 x 29 mm

Housing material

ABC

Weight

100 g

Power Supply

The mini data logger has one 3.6 V lithium thionyl chloride AA battery. The power supply of this battery suffices to carry out measurement and data storage and to operate the wireless interface.

 

Note on the batteries:

The AA batteries are lithium thionyl chloride batteries available in the industrial trade. All RMS input modules are designed for this type of battery. Only batteries of the same type or with identical characteristic values may be used as replacement batteries.

RMS Mini Data Logger

The mini data logger provides the following basic functions:

oMeasurement (temperature, temperature & humidity, barometric pressure, current, voltage, light or switch contact)

oRecording of up to 13,000 data points (B & BT) , 10,000 data values for all other loggers

oTransfer of the recorded data to the RMS software

oCalibration and adjustment of the sensors (via the electronics)

oFirmware update

 

 

Measured Parameters

Depending on the version, the mini data logger has different inputs. The following table lists the main types:

RTCC (Real Time Clock Calendar)

The device has a real time clock calendar. The time is synchronized continuously when connected to the server.

 

 

Data Logging and Measurement Interval

The values of every measurement are saved in the memory with the time stamp. At a measurement interval of one minute, it is possible to save data of one month, which corresponds to 10,000 pairs of measured values. When the ring memory is full, the oldest values are overwritten.

 

 

Indicator and Button

The device has a button and multicolored LED for use and indication of the operating state. The button is used to start the device or switch it off in battery mode. The LED indicates the device status and whether it was possible in the current measurement interval to carry out a valid measurement and send the data to the monitoring system.

 

Important:

 

If the RMS wireless device is offline for a longer period of time, then this may cause for the wireless module to be sent into failure mode. This happens when a very low power supply is supplied to the device. Once the wireless module is in failure mode, it cannot be resuscitated. Once the wireless module has failed, the device's LED will blink differently to any way that is described in the manual.

 

Recommendation: Please remove the batteries if the user anticipates keeping a wireless device disconnected for a longer period of time.

 

Software Compatibility

The logger is designed for use with the RMS server software (local installation or Rotronic Cloud). The data logger can alternatively also be operated with the RMS-Configuration software (standalone software).

 

915 MHz devices are compatible ≥V1.2.1 or higher versions.
