MeloAuto-Trusted PLC & DCS Parts Supplier
The ABB Bailey 1948502A0340 connects expander bus modules across remote I/O racks. This cable provides reliable signal transmission between distributed control system components. It weighs approximately 0.18 kg and comes as a flexible shielded assembly. Its full length measures 340 cm from end to end.
Technical Specifications & Hardware Details
The 1948502A0340 features two 24-pin male connectors at both ends. A braided copper shield surrounds the internal signal wires for noise rejection. This cable stores no electrical energy because it contains no active components. Three primary layers form the complete cable: the conductors, the shield, and the outer PVC jacket.

Cable Construction and Signal Integrity
You can route this cable through standard cable trays or conduit systems. The braided shield prevents electromagnetic interference from nearby power cables. For maximum noise immunity, ground the shield only at one end. The 1948502A0340 supports data rates up to 1 Mbps over its full length.
Installation and Environmental Ratings
You can install this cable in temperatures ranging from -20°C to 80°C. The molded connectors provide excellent strain relief against pulling forces. Furthermore, the PVC jacket resists oils and mild chemicals in industrial environments. Consequently, this interconnect cable requires no maintenance after proper installation. Just inspect connectors for corrosion during routine system checks.
