Allen-Bradley 1771-HODS Converter ODS Module for PLC-5
Product Summary
The 1771-HODS Converter Option ODS module connects handheld pendants and ODS terminals to the 123 Motion Control System. It extends communication up to 393 meters with the longline option. This ensures flexible motion controller integration for precision industrial automation.
Product Procurement & Buyer Guide
Procurement teams need precise module selection for legacy PLC‑5 upgrades. The 1771-HODS is purpose‑built for the 123 Motion Control System and supports two communication standards. Use RS‑232 for a handheld pendant up to 8 meters (25 ft) from the controller. Use RS‑422 for an ODS terminal up to 393 meters (1200 ft) from the controller.

The longline option (1771‑HLL) extends both connections to 1200 ft for remote operation. This solves the pain point of cable length limitations in large manufacturing cells. Buyers must verify compatibility with IMC 123 motion controllers and available termination panels.
Four DIN‑rail‑mounted termination panels increase system flexibility. The Temposonic panel supports linear displacement transducers. The Encoder panel provides one axis plus external power for encoders. The Resolver panel handles single or dual resolver configurations. Choose the panel that matches your feedback device needs.
Step-by-Step User & Installation Guide
Mount the 1771-HODS module on a standard DIN rail using the integral clip. Ensure sufficient clearance for cable connectors and airflow. Connect the RS‑232 port to the handheld pendant using a shielded cable no longer than 25 ft for standard operation.

For the ODS terminal, wire the RS‑422 port to the device respecting polarity and termination resistors. When using the longline option, install the 1771‑HLL adapter between the module and the pendant or terminal. This enables distances up to 1200 ft without signal degradation.
Secure all connections with lock washers to prevent vibration loosening. Power the module from the PLC‑5 backplane; no external supply is needed. Verify communication by sending a test command from the motion controller. The ODS terminal and pendant should respond immediately without errors.
