Product Overview
The Allen-Bradley 1771-HD is a handheld teach pendant designed for programming and modifying PLC 5 controller systems. This device allows operators to comfortably hold and use it remotely, enabling efficient parameter and variable adjustments through the Offline Development System (ODS). It connects via a 25-foot (8-meter) cable to the motion controller module's 9-pin RS-232 port, providing flexibility in industrial environments.

Industry Applications
Operators can adjust system variables on the fly without stopping production, reducing downtime. In automated assembly stations, the 1771-HD enables quick parameter tuning for servo axes, improving cycle times. Its 25-foot cable allows safe remote operation near machinery.
Installation & Setup Guidance
Connect the 1771-HD to the IMC 120 motion controller using the 1771-CAD cable (25-foot RS-232 with 9-pin D-shell). For power, use the 1771-CAS connector cable to an AC source rated at 120V AC or 240V AC. The pendant features hard keys with fixed functions and soft keys that change with the menu display. Use the diagnostic test switch and button to verify operation before deployment.
Maintenance & Reliability
Regularly inspect the cable for wear or damage, especially near connectors. Keep the pendant clean and dry, operating within 5-95% non-condensing relative humidity. Periodically test all keys and the display to ensure proper function. No disassembly is required for routine checks.
Compatibility & Integration
The 1771-HD communicates via RS-232 with servo controller modules. It is designed for use with PLC 5 systems and the IMC 120 motion controller. The pendant offers five selectable menu displays: Jogs, Status, Debug, File Manager, and Teach Position, providing comprehensive control options.
Selection Guide & Purchasing Advice
When selecting a replacement or spare teach pendant, verify compatibility with your existing PLC 5 system. The 1771-HD is a dedicated handheld unit for offline development. AutoDCSTech offers this module for industrial automation needs. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
Troubleshooting & Common Issues
If the display shows no text, check the RS-232 cable connection and power supply. For unresponsive keys, run the built-in diagnostic test. Error messages appear on the 4-line x 16-character display; refer to the IMC 120 system manual for interpretation. Ensure the pendant is within 25 feet of the controller.
