Product Overview
The Allen-Bradley 1771-HODS is a Converter Option ODS module from the PLC-5 series. This module works with the 123 Motion Control System. It connects both the ODS terminal and the handheld pendant to the motion controller. The ODS terminal uses RS-422 communication. The handheld pendant uses RS-232 communication. Users can attach the pendant up to 8 meters away from the motion controller. The ODS terminal can reach up to 393 meters away. For extended range, the 1771-HLL longline option allows connection up to 1200 feet for both devices. This gives flexibility in factory automation setups.
The 1771-HODS module mounts on a DIN rail. It supports four termination panels: Temposonic, Encoder, Resolver, and more. These panels add functions like linear displacement transducer support or encoder power. This module is a key part of the PLC-5 motion control family. It simplifies wiring and reduces installation time. Each component works together to control precise motion tasks.
Application Scenarios
Industrial plants use the 1771-HODS module in many motion control applications. It fits well in packaging machines, material handling, and assembly lines. The ODS terminal provides operator interface for machine setup. The handheld pendant allows manual jogging and troubleshooting. Both devices connect reliably through the motion controller. With the longline option, the module helps in large factory floors where distances are greater. It also supports multi-axis systems when paired with appropriate termination panels. This makes the module ideal for retrofitting older PLC-5 systems.

Installation & Maintenance Guide
Install the module on a standard DIN rail. Ensure the motion controller is powered off. Connect the ODS terminal to the RS-422 port. Use shielded cables for long distances. Connect the handheld pendant to the RS-232 port. For longline use, add the 1771-HLL option between the module and the controller. Secure all wiring with proper strain relief. Test communication after installation. For maintenance, inspect cables regularly. Replace damaged connectors. Keep the module free of dust and moisture. Do not exceed rated distances. Follow Rockwell Automation guidelines for safe operation.
