4-Channel SERCOS III Weight Transmitter

The Laumas TLB4 SERCOS III Weight Transmitter is a multi-channel DIN rail device that provides real-time weight measurement for automation systems using the SERCOS III industrial Ethernet protocol. With four independent load cell inputs, it is ideal for complex multi-sensor installations requiring fast, accurate data transfer and synchronised motion control.

Designed for performance and precision, the TLB4 SERCOS III allows seamless integration into advanced machine and plant control systems where high-speed and deterministic communication is critical.
