Logic mobile controller

The BLM output and logic module is designed for mobile machinery, to take on switching functions or to serve as an input/output module in a CAN system. The module is available with customer-specific software. The PC program ConDoc enables a rapid adaptation to the individual machine data as well as a comprehensive diagnosis. Alternatively BLM is offered as programmable logic controller (PLC). Thus it combines the advantages of the proven BLM mobile controller with the advantages of free programming according to the international standard IEC 61131-3.


  • Robust aluminum housing for outdoor use, equipped with a ventilation membrane and a status LED, protection category IP65, IP69K
