Rossonix Co., Limited is proud to offer the Allen Bradley 1747-ASB SLC 500 System I/O Adapter Module (also referred to as 1747ASB). With over a decade of experience in industrial automation supply and an annual export value exceeding US$5 million, we ensure that every module we deliver meets rigorous quality standards. This 1747-ASB adapter is a critical component for expanding your SLC 500 system's I/O capacity, enabling seamless communication between the processor and remote I/O racks. Whether you are upgrading an existing line or building a new control system, this module provides reliable, high-speed data transfer and flexible configuration options.

The 1747-ASB acts as a remote I/O scanner/adapter, allowing the SLC 500 processor to control up to 12 logical racks with up to 30 I/O modules each. It supports both discrete and analog I/O, making it suitable for a wide range of applications including manufacturing, packaging, material handling, and process control. Its compact design fits directly into the SLC 500 chassis, saving valuable panel space while delivering robust performance in harsh industrial environments.

Key Features & Technical Specifications

Remote I/O Communication: Supports both scanner and adapter modes, providing flexible network topology.
High Capacity: Manages up to 12 logical racks (each rack can hold up to 16 I/O modules, with a maximum of 30 modules per rack in special configurations).
Fast Data Transfer: Utilizes the Allen Bradley Remote I/O protocol with baud rates of 57.6, 115.2, or 230.4 kbps.
LED Diagnostics: Front-panel LEDs indicate module status, communication activity, and fault conditions for easy troubleshooting.
Backplane Powered: Operates on 5V DC from the SLC 500 chassis backplane, eliminating the need for external power.
Wide Temperature Range: Rated for 0°C to 60°C (32°F to 140°F), suitable for most industrial environments.
Compatibility: Works with SLC 5/02, 5/03, 5/04, and 5/05 processors, as well as other Allen Bradley controllers that support Remote I/O.
Rugged Design: Built to withstand vibration, shock, and electrical noise common in factory floors.

Frequently Asked Questions

Q: Is the 1747-ASB compatible with SLC 5/01 processors?
A: No, the 1747-ASB requires a processor that supports Remote I/O, such as the SLC 5/02, 5/03, 5/04, or 5/05. It is not compatible with the SLC 5/01.
Q: How many I/O modules can I connect to one 1747-ASB?
A: The module supports up to 12 logical racks, each capable of holding up to 30 I/O modules, depending on the addressing scheme. In practice, the total number of I/O points is limited by the processor's memory and the RIO network.
Q: Does this module require any special configuration software?
A: The 1747-ASB is configured through the SLC 500 programming software (RSLogix 500). You set the node address, baud rate, and rack assignments via the software or DIP switches on the module.
Q: Can I use the 1747-ASB in a redundant system?
A: The 1747-ASB itself does not support redundancy. For redundant I/O applications, you would need specialized modules like the 1747-SN or a different architecture.
Q: What is the maximum cable length between the processor and the 1747-ASB?
A: The maximum distance depends on the baud rate: at 57.6 kbps, up to 10,000 feet (3,048 m); at 115.2 kbps, up to 5,000 feet (1,524 m); at 230.4 kbps, up to 2,500 feet (762 m). Use Belden 9463 or equivalent cable.
Q: Is this module new or used?
A: Rossonix offers both new and refurbished/tested units. Please check the product listing or contact us for specific condition details. All units are fully tested before shipment.
Q: Does the 1747-ASB support analog I/O modules?
A: Yes, it supports both discrete and analog I/O modules as long as they are compatible with the SLC 500 chassis and the processor's addressing.
Q: What is the warranty period for this module?
A: Rossonix provides a standard one-year warranty against defects in materials and workmanship. Extended warranties are available upon request.
