Laumas TLB4 Multi-Channel Digital Weight Transmitter 

The Laumas TLB4 Weight transmitter is suitable for back panel mounting on Omega/DIN rail. Constructed in a space-saving vertical shape, with dimensions: 25x115x120 mm. It has a 6-digit semi-alphanumeric red LED display (8 mm height) and 6 signaling LED. Built with Four buttons for the system calibration and extractable screw terminal blocks, and 4 independent reading channels for load cells (individual load cell monitoring, total weight displaying, digital equalization).

• Semi-automatic zero.
• Displaying of the maximum weight value reached (peak).
• Direct connection between RS485 and RS232 without a converter.
• Hysteresis and setpoint value setting.

Single Product Program:

• Settable dosage formula.
• Automatic fall calculation.
• Tolerance error control.
• Precision batching through slow function.
