Allen-Bradley 1747-PIC

Overview

The Allen-Bradley 1747-PIC is a legacy communication interface converter designed to connect a computer’s RS-232 serial port to an SLC 500 processor’s DH-485 communication port. It provides a reliable bridge between the programming software (RSLogix 500) and older Allen-Bradley controllers that use the DH-485 protocol. The 1747-PIC is ideal for maintenance and configuration of existing systems that use these legacy controllers.
