The Laumas TLM8 PROFIBUS is an 8-channel digital weight transmitter for analog load cells, combining digital equalization, automatic diagnostics, local LCD/keypad setup, RS485 communication, and a dedicated PROFIBUS DP interface.
Use this model when a multi-load-cell scale, tank, hopper, platform, or process weighing system needs individual channel monitoring and direct PLC or host integration.

Use one transmitter for up to eight analog load-cell channels with digital equalization.
Select this TLM8 version when the control system requires PROFIBUS DP communication.
Use the TEST key, channel diagnostics, and load distribution checks during service and commissioning.

This page represents the TLM8 PROFIBUS protocol family. Related ordering codes can include display, enclosure, OEM, legal-for-trade, and accessory variations, so WeightechUSA should confirm the exact code before release to production.
Send the load-cell count, scale type, PLC protocol, enclosure requirement, power, and legal-for-trade target and we will confirm the correct TLM8 configuration.
