As a trusted supplier in the industrial automation components sector since 2011, Rossonix Co., Limited is pleased to offer the genuine Allen-Bradley 1747-DPS2 SLC 500 Port Splitter. We understand the critical need for reliable and efficient system configuration in manufacturing environments. This device is a vital tool for engineers and technicians working with the extensive installed base of SLC 500 controllers, enabling enhanced connectivity and workflow without compromising system integrity. Our commitment to quality, backed by ISO9001 certification, ensures you receive a component that meets the high standards demanded in global markets across North America, Europe, and Asia.
The Allen-Bradley 1747-DPS2 is an essential accessory designed to address a common challenge in PLC programming and maintenance: single-port contention. The SLC 500 controllers typically feature one programming port. The 1747-DPS2 elegantly solves this by splitting this single port, allowing two devices—such as a programming terminal and a Human-Machine Interface (HMI) panel—to be connected simultaneously. This eliminates the need for constant cable swapping, reduces downtime during configuration changes, and improves overall system accessibility.
Core Features and Technical Advantages:
- Simultaneous Multi-Device Access: Enables a programming device and an operator interface to communicate with the SLC 500 PLC at the same time, streamlining commissioning and troubleshooting processes.
- Enhanced Diagnostic Capabilities: Facilitates real-time monitoring via an HMI while program edits are made, allowing for immediate observation of system behavior changes.
- Robust Industrial Design: Manufactured to Allen-Bradley's stringent quality standards, ensuring reliable performance in typical industrial environments with respect to electrical noise and mechanical durability.
- Plug-and-Play Operation: Requires no external power supply or complex configuration. It interfaces directly with the controller's existing communication port.
- Backward Compatibility: Designed specifically for the SLC 500 series, ensuring full compatibility with a wide range of processors and I/O configurations within that family.

Frequently Asked Questions (FAQ)
Q1: What is the primary purpose of the Allen-Bradley 1747-DPS2?
A1: The 1747-DPS2 is a port splitter designed for Allen-Bradley SLC 500 series Programmable Logic Controllers (PLCs). Its main function is to allow two communication devices, such as a programming laptop and an operator terminal (HMI), to be connected to the controller's single programming port at the same time.
Q2: Is this device compatible with all SLC 500 processors?
A2: Yes, the 1747-DPS2 is designed to be compatible with the entire SLC 500 family of processors. It interfaces with the standard RS-232 programming port found on these controllers.
Q3: Does the 1747-DPS2 require any external power source or configuration?
A3: No, it is a passive device. It draws minimal power from the communication signals of the SLC 500 port itself and requires no separate power supply or software configuration for basic operation.
Q4: Can I use it to connect two programming computers simultaneously?
A4: While physically possible, it is not recommended. The port is intended for one programming device and one other device, typically an HMI. Two active programming sessions could cause communication conflicts.
Q5: What type of cables are needed to connect the 1747-DPS2?
A5: You will need standard Allen-Bradley serial communication cables compatible with the SLC 500 controller (e.g., 1747-CP3, 1747-CP13) to connect the splitter to the PLC. Separate cables will then run from the splitter's output ports to your programming device and HMI.
Q6: Is this product new, used, or refurbished?
A6: The condition (new, refurbished, etc.) is specific to each individual listing. Please check the product listing details or contact us directly for the specific condition of the unit you are interested in. We ensure all units, regardless of condition, are fully tested for functionality.
Q7: Do you offer any warranty or support for this product?
A7: As a trading company, we provide a standard warranty on the products we supply, the terms of which can be confirmed at the time of inquiry. We also offer basic technical support regarding compatibility and integration.
Q8: What are my shipping options, and what are the lead times?
A8: We ship globally from ports including Shenzhen, Hong Kong, and Europe. Lead times and shipping costs depend on the destination and the selected shipping method. We work with reliable logistics partners to ensure safe and efficient delivery to our wide range of main markets.
