AB 1784-KT Communication Interface Module

Product Description

The Allen-Bradley 1784-KT is a communication interface module designed to connect personal computers to Allen-Bradley PLC-2, PLC-3, and PLC-5 controllers. It enables a computer to act as an active node 

on a Data Highway Plus (DH+) network, providing increased application response time and a single cable connection to multiple controllers.

Key Features and Benefits

• Data Highway Plus Connectivity: Connects to DH+ networks for high-speed communication between the computer and PLC.

• Increased Application Response Time: Provides faster data transfer rates compared to RS-232 networks.

• Single Cable Connection: Simplifies system setup and reduces wiring requirements.

• Address Selectable: Allows for flexible configuration within the network.

• Compatibility: Works with PLC-2, PLC-3, and PLC-5 controllers.

Specifications

• Card Type: ISA card

• Interfaces: DH+, PLC-2 serial, PLC-3 serial

• Baud Rate: Asynchronous (PLC-2 & PLC-3 CPUs) – 9.6/19.2 Kbps, Synchronous (Data Highway Plus) - 57.6 Kbps

• Power Requirements: +5VDC @ 0.4A, +/-12VDC @ 0.04A

• Operating Temperature: 32 to 130 degrees Fahrenheit

• Humidity: 5 to 95%

Precautions

• Compatibility: Ensure the module is compatible with the specific PLC and computer system.

• Installation: Follow the manufacturer's instructions for proper installation to avoid damage.

• Environment: Protect the module from excessive heat, moisture, and vibration.

• Maintenance: Regularly inspect the module for signs of wear or damage.

Applications

• Data Acquisition: Collect data from PLCs for analysis and reporting.

• Remote Monitoring: Monitor and control PLC systems from a remote location.

• HMI: Create custom human-machine interfaces for PLC applications.

• SCADA: Integrate PLC systems into supervisory control and data acquisition systems.

Additional Information

• End-of-Life: The 1784-KT is an older product and may be end-of-life. Consider alternative solutions or refurbished units.

• Compatibility: While the module is designed for older PLC models, it may still be compatible with newer systems depending on the specific configuration.

• Support: Refer to the manufacturer's documentation or contact technical support for specific questions or troubleshooting.
