The line transformer 00LTD03 is designed for FSK channels with 9.6kBd and to isolate and protect the RTU500 series Modems 23WT24 and 560FSM11 from the telecontrol line. Moreover it can also be connected to other data terminal equipments. It operates at a frequency range from 2 kHz to 50 kHz and is optimized for line impedances of 150 Ohms which applies to above mentioned modems.
The document provides technical specifications for the ABB 500LTDO3 DSL Line Transformer. It is designed for DSL channels with speeds up to 7168 kbps, operating within a frequency range of 1 kHz to 1 MHz and optimized for line impedances of 100 Ohms.
The transformer isolates and protects specific RTU500 series modems (including models 560NMD01, 500NMD02, 560NMD11, 560NMS24, and 560NMS34) from the telecontrol line. It features a 1:1 ratio, passive power supply, and mounts on a 35 mm DIN rail.
