Network termination module LT-04

Network termination module LT-04

LT-04

The LT module is used for termination, polarization and amplification of the signal line of the RS-485 network.

Functioning
Termination means ending the signal line (UTP wire) with suitable resistances in order to maintain a consistent wave resistance across the line, which greatly improves the quality of transferred data and eliminates errors that emerge on the signal line. Line polarization is performed in case where at least one of the Slave-type devices in the RS-485 network does not have a GND signal point. Polarization is performed only for the MASTER-type device. Signal amplification is done via active power supplying of the line with low voltage through one of the modules.
