Allen-Bradley - 1747-PIC - RS-232 to DH-485 Interface Converter

The Allen-Bradley 1747-PIC is an interface converter designed to facilitate communication between devices with RS-232 ports and those utilizing the DH-485 protocol, commonly found in SLC 500 series controllers. This converter enables seamless integration of personal computers and programming devices with Allen-Bradley PLCs that operate on the DH-485 network. 

Key Features:

• Protocol Conversion: Translates RS-232 signals to DH-485 protocol, allowing RS-232 devices to communicate with DH-485 networks. 

• Compatibility: Supports SLC 5/01, SLC 5/02, and SLC 5/03 processors, enabling programming and monitoring via compatible software. 

• Connectivity: Equipped with a 9-pin D-shell connector for RS-232 connections and a 6-pin Phoenix connector for DH-485 network interfacing. 

• Power Supply: Draws power directly from the connected RS-232 port, eliminating the need for an external power source.

Technical Specifications:

• Dimensions: Compact design for easy integration into existing setups.

• Operating Temperature: 0°C to 60°C (32°F to 140°F). 

• Storage Temperature: -40°C to 85°C (-40°F to 185°F). 

• Humidity: 5% to 95% without condensation. 

Important Considerations:

• Port Compatibility: The 1747-PIC is compatible only with built-in COM1 and COM2 serial ports on personal computers. It does not function with USB-to-serial adapters, serial port extender boards, or PCMCIA-format serial port cards.  

• Operating System: Ensure that the appropriate drivers are installed for your operating system to facilitate proper communication.

• Alternative Solutions: For computers lacking built-in serial ports or using modern operating systems, the 1747-UIC USB to DH-485 interface converter is recommended as an alternative to the 1747-PIC.
