HYGIENIC UNIVERSAL DIGITIZER FOR LOAD CELLS
COMING SOON
MICRO USB FOR
PC CONFIGURATION
DESCRIPTION
LCB3A transforms an analog load cell (mV/V output) into a digital one; it can also be used on existing load cells to digitize the weighing
system.
Hygienic device RPSCQC authorized by 3-A SSI.
Conceived for IoT applications (Internet of Things).
PC configuration software via micro USB port.
Status LED of the communication interface.
Mounting: wired or integral to the load cell body via standard ¼ GAS fitting (specific adapters for different threads are supplied on request).
IP67 AISI 304 stainless steel box (dimensions: 90x40x107 mm including flying connectors).
3 M12 hygienic connectors with solder terminals included in the supply.
The instrument can be configured and managed using the free “Instrument Manager” PC software, which you can download from www.
laumas.com.
INPUTS/OUTPUTS AND COMMUNICATION
1 micro USB port.
3 relay outputs controlled by the setpoint values or via protocols.
2 digital inputs: status reading via serial communication protocols.
1 load cell input.
CERTIFICATIONS
Complies with the Eurasian Custom Union regulations
Equivalent of the CE marking for the United Kingdom
American standard that regulates the design, production and use of hygienic equipment
