The Laumas TLS is a DIN-rail weight transmitter with 4 load cell inputs, a 16-bit analog output, RS485 Modbus RTU communication, and a 6-digit LED display. It supports up to 8 pcs of 350-ohm load cells and is rated ATEX Zone 2-22 for hazardous environments with an ATEX-approved enclosure.
The TLS weight transmitter is a practical, multi-input solution for weighing systems that require a single analog output to drive a PLC or controller. With 4 dedicated load cell inputs and support for up to 8 pcs of 350 Ohms load cells in parallel via junction box, it suits platform scales, tank weighing, and process automation where a compact, rail-mounted transmitter must deliver a stable, high-resolution analog signal.
The TLS communicates via RS 485 using Modbus RTU, ASCII Laumas, or continuous one-way transmission protocols, and connects to remote displays and PC’s. Its 16-bit optoisolated analog output – configurable as 0-20 mA, 4-20 mA, 0-10 V, 0-5 V, ±10 V, or ±5 V – drives virtually any PLC analog input or data acquisition system. Two optorelay outputs handle setpoint-triggered switching for alarm or process control functions.
For demanding environments, the TLS is available in an IP67 polycarbonate enclosure and an ATEX II 3GD (Zone 2-22) certified version – broadening its application to chemical plants, grain handling, and other classified hazardous locations. Configuration is handled via the free Instrument Manager PC software.
Most Common Applications: Tank and silo weighing, platform scales, hopper and bin weighing, batching and filling lines, process automation, hazardous area weighing (ATEX version).
