DESCRIPTION MAIN FUNCTIONS
Weight indicator in DIN box suitable for front panel mounting. Connections to:
Dimensions: 96x48x130 mm (drilling template: 92x45 mm). - PLC via analog output (on request);
6-digit semi-alphanumeric red LED display (14 mm height). - PC/PLC via RS485/RS232 (up to 99 instruments with line
8 signalling LED. repeaters, up to 32 without line repeaters);
4-key keyboard. - remote display and printer via RS485/RS232;
IP54 front panel protection rating (IP65 front optional). - up to 8 load cells in parallel by junction box;
Real-time clock/calendar with buffer battery. - intelligent junction box or other multichannel instruments: allow
the use of advanced functions as digital equalization, load
Removable screw terminal blocks. distribution analysis and automatic diagnostics.
The instrument can be configured and managed using the free - IoT gateway for cloud connection via RS485.
“Instrument Manager” PC software, which you can download from
www.laumas.com. Digital filter to reduce the effects of weight oscillation.
Theoretical calibration (via keyboard) and real calibration (with
sample weights and the possibility of weight linearization up to
8 points).
INPUTS/OUTPUTS AND COMMUNICATION Tare weight zero setting.
Automatic zero setting at power-on.
RS485/RS232 serial ports for communication via protocols Gross weight zero tracking.
ModBus RTU, ASCII Laumas or continuous one way transmission. Semi-automatic tare (net/gross weight) and preset tare.
5 relay outputs controlled by the setpoint values or via protocols Semi-automatic zero.
(4 outputs if analog output is present). Displaying of the maximum weight value reached (peak).
3 optoisolated PNP digital inputs: status reading via serial Direct connection between RS485 and RS232 without converter.
communication protocols (2 inputs if analog output is present). Hysteresis and setpoint value setting.
1 load cell dedicated input. Weight value printing with date and time via keyboard or external
contact.
Current or voltage 16 bit optoisolated analog output (option on request).
The indicator can be used as a remote display with setpoint.
12 groups selection by 5 setpoint via external selector switch or
contact (option on request).
Labeling machine management.
Approved versions for legal for trade use
