Data sheet


The control unit ModWeigh DI is a modern and comfortable processing system for loss-in-weight weighing processes. It is constructed in order to analyse the load cell signals as well as to regulate dosing tasks in loss-in-weight feeders and micro feeders.

The ModWeigh DI comfort has a modular design: transmitter MT1, module MR1 as well as a display and operator module MD1.


The control unit provides and records data such as the current flow rate, the amount, the statical weighing value of the hoppers content as well as some process status information, e.g. end of charging.


Features of the ModWeigh DI comfort:

  • Easy to operate via keypad and comfortable menu control in German and English
  • By default are available: several digital inputs and outputs, pulse input and output, one analog input and two analog outputs as well as two serial interfaces (for printer and gateways for fieldbus interfaces)
  • Plug-in contact blocks which simplify the installation, maintenance and service
  • Plug & Play function via data stick


The control unit ModWeigh DI comfortgenerates the flow rate directly from the weight loss and controls the speed of scale‘s drainage system.


The determined weight value is displayed on the ModWeigh MD1 display according to the user-defined settings. In addition, the measured value "current flow rate" is available as a signal at the analog output as well as the "total quantity" at the pulse output.


The measured data can either be directly transmitted via the COM interface and Modbus RTU-protocol to the other Modbus-participants or can be provided at fieldbus interfaces.


The overruns of the characteristics are noted in the alarm memory, e.g. Flowrate default. The error list can be called and elected on the display.


The control unit is equipped with a data stick saving all parameters of the scale. In case of dysfunction of the weighing module, the stick can simply be put into the new module in order to make all scale parameters available (plug & play).
