PWBS331 DC powerline communication long distance 485 tree star network 485

KEY FEATURES

• Delivery both of the power and BUS data on only two wires. No need isolated design. Excellent anti-interference ability. Can work close to AC power lines
• Allows to 500 slave nodes on the BUS (compatible to RS485 with one RS485 chip)
• Achieves to 3000m in ideal environment
• Non-polarity. Easy to use in engineering field.
• Supports to any network: Tree, star, BUS
• No type limit on BUS wires
• Supports 17 to 48V on the BUS
• Transparent UART interface, compatible to RS485 interface directly
• Self adaption to 9600bps and 2400bps in half-duplex
• Low cost solution
• Free design in isolation or non-isolation. Guarantee the best EMC performance because of the high power BUS lines.

DESCRIPTION

PWBS331 is the slave node's chip which works with the host PWBS751 to communicate and get power from the square wave BUS.

PWBS331 simplifies the traditional separated solution of power and communication data lines by the way of transmitting signal on two DC lines by full amplitude DC voltage pulse wave and receiving signal by current. That guarantees the highest reliable communication result in industry.

PWBS331 adapts to any type of the wires, and can work in any topology network with no polarity limit. That simplifies the engineering connection of BUS lines.

PWBS331 works with host module PWBS751 to delivery both of the power and signal data.
