Function Features

Interface function: Allen Bradley 1734-APB simultaneously resides on the point I/O backplane (point bus) and the Profibus network, enabling seamless interfaces between the point I/O modules and the Profibus network system.

Master/slave capabilities: On the point bus, Allen Bradley 1734-APB functions as a master unit and communicates with a maximum of 63 point I/O modules while acting as the slave unit on Profibus. I/O data exchange occurs between Allen Bradley 1734-APB and Profibus master.

Power conversion: It converts applied field power of 12-24 volts DC on the point bus (5 volts) logic power to point I/O modules.

Diagnostics and configurability: Full diagnostics and configurable settings make it a convenient unit for applying and troubleshooting point I/O systems.

Hot swapping: The removal and insertion under power (RIUP) feature of Allen Bradley 1734-APB  allows you to replace modules while the system is powered on, thus minimizing downtime.

Modular Design: Modular construction permits independent selection of I/O, termination style, and network interface, thus allowing for flexibility in configuring the system.

Protection Options: Allen Bradley 1734-APB  has input overvoltage protection and reverse current protection, thereby protecting other components and equipment connected to the same module from damage.

Conformal coating option: It is also available with a conformal coating that adds extra protection against environmental stressors, such as moisture, dust, and chemicals.
