About the LCB3A

Digitizer/Weight Trasmitter for load cells conceived with an eye on IoT (Internet of Things). Three M12 hygienic connectors with solder terminals. Six indicator led of the communication interface. Dimensions: 90x40x107 mm including connectors.IP67 junction box made of stainless steel AISI 304, certified 3-A Sanitary Standards.

LCB Digitizer transforms an analog load cell (output mV/V) into digital
and can also be used on existing load cells or strain gauge sensors.
Designed for an assembly/wiring integral with the load cell body, it can
be connected by fieldbus to PLCs of the most important international
brands. The weight calculation frequency reaches up to 500 values a second and also the update frequency of the data on the fieldbus can reach the maximum speed of 500 updates a second, when using the PROFINET, EtherNet/IP and EtherCAT buses.
