Overview
PB331 is a slave communication IC for POWERBUS technology. POWERBUS is a low-voltage power bus technology. By modulating control signals over the power cable, it eliminates the need for separate control and power cables used in traditional systems, while significantly improving communication reliability. POWERBUS employs voltage transmission with current signal return, providing high immunity to communication interference. PB331 is compatible with various field cables and supports long-distance communication. Cables can be deployed in any topology — bus, tree, or star — greatly simplifying installation and wiring, preventing miswiring, and reducing maintenance complexity. PB331 can fulfill both power supply and communication requirements for devices via the POWERBUS bus.
