CANopen Weight Transmitter for Load Cells

The Laumas TLB CANopen Weight Transmitter is a DIN rail-mounted device designed to convert signals from a single load cell into a digital CANopen output. Engineered for integration with CANopen networks in industrial automation systems, it provides fast, accurate weight transmission while maintaining a compact footprint.

Supporting both 4-wire and 6-wire load cells (minimum impedance 350 Ω), the TLB offers high-speed data processing and advanced digital filtering. It can be calibrated using theoretical values or real weights and configured via PC software or an optional local display terminal.
