Pepperl+Fuchs has expanded its M-LB-2000 signal line protection system with the addition of the M‍-‍LB‍-‍2600 modules, specifically developed for 3-wire transmitters and sensors.

Housed in the same compact 6 mm design, these variants are designed to deliver enhanced protection and precision, particularly in applications where accuracy is critical. Compared to conventional 2-wire systems, 3-wire measurement offers a significant improvement in performance by eliminating the influence of line resistance on signal accuracy. In a 3-wire setup, three distinct circuits enable compensation for lead resistance, ensuring voltage drops along the connection cables do not distort the final measurement. This results in higher accuracy, greater stability and the ability to cover longer cable distances without compromising signal integrity.

The M-LB-2600 modules are available in eight new variants, offering flexible protection for a wide range of signals from or to both hazardous and non-Ex areas. From 24 V control signals to sensitive low-voltage applications such as temperature measurement, the modules support diverse topologies while helping to maintain performance and safety.
