RS485 Weight Transmitter for Industrial Automation

The Laumas TLB RS485 is a compact DIN rail-mounted weight transmitter, ideal for precision weighing in automated industrial systems. Equipped with an RS485 interface and Modbus RTU protocol, it ensures robust and fast communication with PLCs, SCADA systems, and remote I/O devices.

Designed to handle a single load cell (4- or 6-wire), the transmitter provides fast conversion speeds, programmable digital filtering, and supports both real and theoretical calibration. This makes it an efficient and flexible solution for machine integration and process control applications.
