Product Overview

The 1771-HS3A is an Allen-Bradley PLC-5 series three-axis servo controller module designed for installation in a Bulletin 1771 I/O chassis. It executes motion control functions in servo-based systems by managing encoder/resolver feedback and providing analog command outputs. Typical applications include machine motion sequencing, precision positioning control, and integration in legacy automation systems. The module requires associated components such as the 1771-PS7 power supply and 96 KB memory cartridge for AMP parameters and program storage.
