LOAD CELL - INSTRUMENTS

                  DIN RAIL MOUNT-CE APPROVED-PC SYSTEMS 

High quality load excitation module. 

The Digital Amplifier, DAD141.1 is an all-in-one device for non-automatic and automatic weighing, filling or loss-in-weigh operations. The standard device includes all the communication facilities needed for industrial weighing, control and registration, i.e. analog current- and voltage output, Ethernet, RS485 and logic I/O’s for direct control of valves or bars and simple remote operations.

The DAD141.1 is a stand-alone device for DIN-rail mounting (TS35).An App for Android enables set-up and calibration of the DAD141.1 via most smart phones and tablets.

To grant the quality and allow legal weighing the DAD141.1 is OIML R-76 approved and tested to meet the MID requirements to EMC at industrial surroundings.   

NEW option for DAD141.1  

Small PC board UIA149.1 make it now possible via the 7 load cell terminals to connect other type of sensors with Volt or 4-20mA input and still use all the nice facilities which are in the DAD141.1 also the DOP Free PC software.

NOW ALSO IN PROFIBUS VERSION

DOP free Download PC software to be used with DAD141.1 can also be used as Calibration of the DAD141.1
