产品介绍
The Allen-Bradley 1747-PIC Interface Converter is a communication interface device designed for SLC™ 500 programmable controller systems, specifically for use with the SLC 5/03 series processors. Its primary role is to convert RS-232 serial communication to RS-485 (DH-485), enabling reliable communication between a programming terminal and SLC 500 controllers.
The 1747-PIC is commonly used as a programming and diagnostic interface, allowing engineers to connect a PC or handheld programming device to DH-485 networks. By handling signal conversion and protocol compatibility, it ensures stable data exchange without requiring internal communication modules.
This interface converter is widely applied in legacy and long-life automation systems where DH-485 remains an essential communication standard. Its straightforward operation and proven reliability make it a standard accessory in SLC 500 maintenance and commissioning workflows.
