PROFIBUS DP Network Adapter Allen-Bradley 1734-APB

Product Overview

The Allen-Bradley 1734-APB is a PROFIBUS DP Network Adapter. It belongs to the POINT I/O series. This adapter links the PROFIBUS network to POINT I/O modules. On PROFIBUS, it acts as a slave device. On the PointBus backplane, it functions as a master. The 1734-APB uses a 24V DC input voltage. It provides field side power of 400 milliamps. The inrush current is 6 amps for 10 milliseconds. Power consumption is 8 watts. Power dissipation is 2.8 watts at 28.8 volts. The adapter includes reverse polarity protection for input overvoltage. It maintains output voltage for 10ms during drops at 10V with maximum load.

Application Scenarios

This adapter works well in industrial automation settings. Use it to connect a PROFIBUS DP master to I/O modules. It supports up to 63 POINT I/O modules. The 1734-APB is ideal for reliable data exchange. Common uses include manufacturing lines, process control, and machine building. It can power up to 14 I/O modules. The maximum field power is 10 amps. The current draw is 75 milliamps. It converts 12-24V DC field power to 5V logic power for modules. Use a SELV, Class 2, or PELV power supply for CE compliance.
