SST-PB3-CLX-RLL | Allen-Bradley | ControlLogix Profibus DP Communication Module

Product Overview

The SST-PB3-CLX-RLL functions as a high-performance Profibus DP communication interface specifically designed for the Allen-Bradley ControlLogix 1756 platform. This in-chassis module enables seamless data exchange between the Logix backplane and Profibus DP field devices. It serves as a critical bridge for hybrid automation environments, allowing a ControlLogix CPU to master distributed I/O, drives, and instrumentation on a Profibus network. We supply this unit as 100% Brand New original stock to ensure maximum network stability and compliance with industrial communication standards.

Technical Specifications

The SST-PB3-CLX-RLL occupies a single slot and provides robust throughput for high-density I/O configurations:

Engineering Advantages

The SST-PB3-CLX-RLL addresses complex integration challenges in multi-vendor automation environments:

• High-Speed Determinism: The module supports transmission rates up to 12 Mbaud. This ensures rapid update times for motion control and critical interlocking logic across the Profibus network.

• Flexible Slot Placement: You can install the module in any available slot of a local or remote 1756 ControlLogix chassis. This flexibility simplifies hardware layout in crowded control cabinets.

• Massive Slave Capacity: A single module manages up to 125 DP slaves. This high density reduces the number of required communication cards, lowering the overall hardware footprint and power consumption.

• Simplified Configuration: The RLL (Remote Ladder Logic) support allows for streamlined data mapping. It eliminates complex messaging blocks, allowing the ControlLogix processor to treat Profibus I/O as native tags.

FAQs

Can the SST-PB3-CLX-RLL operate as a Profibus Slave?

Yes. While engineers primarily use this module as a DP Master to control field devices, it also supports DPV0 Slave functionality. This allows a ControlLogix system to appear as a high-level I/O device to another master controller, such as a Siemens S7 PLC.

What cable is required for the network connection?

The module utilizes a standard 9-pin D-Sub female connector. You must use a shielded, twisted-pair Profibus-certified cable with appropriate termination resistors at both ends of the segment to prevent signal reflection.

How does this module handle Honeywell PlantScape integration?

The SST-PB3-CLX-RLL carries specific compatibility for Honeywell PlantScape systems. It integrates directly into the PlantScape architecture through the ControlLogix backplane, enabling Honeywell controllers to access Profibus instrument data without external third-party gateways.

Is this unit a refurbished or used component?

No. We guarantee that every SST-PB3-CLX-RLL shipped is 100% Brand New and remains in its original manufacturer packaging. This ensures the 850 mA backplane power draw and internal communication ASICs meet original factory tolerances.
