Product description

The Allen-Bradley 1770-KF2 is a communication interface module designed to connect asynchronous devices, such as computers or serial equipment, to Allen-Bradley's Data Highway (DH) or Data Highway Plus (DH+) networks. It features multiple communication ports, including Data Highway, Peer Link, DH Monitor, and an asynchronous serial port, supporting baud rates up to 57.6 kbps for DH/PCL and 110-9600 bps for asynchronous links. It operates on 115/230 VAC power.

This module is crucial for integrating legacy systems and devices into modern industrial automation networks. Its primary applications involve enabling communication between PLCs (like PLC-2, PLC-3, PLC-4, PLC-5), HMI devices, and computer systems over established Allen-Bradley networks. The tabletop design is suited for controlled environments, making it ideal for network troubleshooting and serial device interfacing.
