Allen-Bradley 1771-HODS Converter Option ODS Module for PLC-5

Technical Specifications Breakdown

Key parameters for the 1771-HODS are listed below for quick reference:

Industry Applications

Extended Operator Interface for Machining Centers

In CNC machining environments, the handheld pendant must be within reach of the operator while the controller is housed in a cabinet. The 1771-HODS allows the pendant to connect up to 8 meters (25 cable feet) away via RS-232, reducing operator fatigue and improving workflow.

Long-Distance Remote Monitoring for Material Handling

For conveyor systems or automated warehouses, the ODS terminal can be placed up to 393 meters (1200 cable feet) away using RS-422.

Flexible Configuration with Longline Option

When using the 1771-HLL longline option, both the handheld pendant and ODS terminal can be extended up to 393 meters from the motion controller module. This flexibility supports complex layouts where equipment is spread across multiple zones.

Installation & Setup Guidance

Mount the 1771-HODS on a DIN rail in the same enclosure as the motion controller or in a nearby panel. Use the appropriate termination panel from the four available options:

• Temposonic panel for linear displacement transducers
• Encoder panel for single-axis encoder support with external power
• Resolver panel for single or dual resolver configurations

Connect the RS-232 port to the handheld pendant (max 8 meters) and the RS-422 port to the ODS terminal (max 393 meters). For longer runs, install the 1771-HLL longline option between the module and the pendant. Verify all wiring per the PLC-5 installation manual to avoid ground loops.

Maintenance & Reliability

Inspect the DIN rail mounting and terminal connections annually for signs of vibration or corrosion. Ensure the ambient environment stays within the PLC-5 series operating range (refer to system documentation). The module has no user-serviceable internal parts; if communication errors persist, check cabling and the longline option first.

Addressing Connectivity Challenges in Motion Control

Industrial motion control systems often require flexible operator interfaces located far from the controller. The Allen-Bradley 1771-HODS Converter Option ODS module solves this by bridging the 123 Motion Control System with both an ODS terminal and a handheld pendant. This module, part of the PLC-5 series, eliminates the need for custom cabling or signal repeaters in typical setups.

Compatibility & Integration

The 1771-HODS is designed exclusively for the 123 Motion Control System within the PLC-5 architecture. It supports RS-232 and RS-422 communication protocols, making it compatible with standard ODS terminals and handheld pendants. The four termination panels provide flexibility for different transducer types (Temposonic, encoder, resolver) without additional adapters.

Selection Guide & Purchasing Advice

When ordering the 1771-HODS, confirm that your system includes the 123 Motion Control Module and that you have the correct termination panel for your transducer. AutoDCSTech stocks this module along with the 1771-HLL longline option and all four termination panels. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
