What is the B&R X20CMR111?

Measurement and evaluation of the ambient conditions in the control cabinet

Recording ambient conditions

Recording operating hours and power-on cycles

Saving user data directly on the module

Technology Guarding directly on the module

Supports blackout mode

2 inputs for PT1000 temperature sensors

2 digital inputs 24 VDC

1 digital output 24 VDC

The module is designed for measuring ambient conditions in the control cabinet as well as recording operating hours and power-on cycles. In addition, the module offers the option of storing user data directly on the module, is equipped with a Technology Guard as well as inputs/outputs and supports blackout mode.

Measuring and evaluating ambient conditions

The ambient conditions are continuously evaluated by the module. The duration in which individual parameters are within certain ranges is stored internally. This makes it possible, for example, to determine how long the system remained in a certain temperature range. The histograms recorded by the module can be read out by the user.

Internal module memory for user data

With 512 kB nonvolatile user memory (flash), data from the application can be saved directly on the module and also read back from the module. The data is therefore retained after the module or CPU is restarted and remains with the module in the event that the module is connected to another machine or system, for example . Data retention is maintenance-free – without batteries.

Technology Guarding

With the integrated Technology Guard, it is possible to implement license protection directly via the module instead of the USB dongle. The same functions can be used as with the USB dongle.

Inputs/Outputs

The module is equipped with 2 inputs for PT1000 temperature sensors, 2 digital inputs (24 VDC) and 1 digital output (24 VDC) .

Blackout mode

The integrated blackout mode ensures that module functionality is maintained even in the event of network failure.
