The Allen-Bradley 1746-HSRV is a servo control module from the SLC 500 series, designed for precise motion control in industrial automation applications. This 1746-HSRV module is compatible with SLC 5/03, SLC 5/04, and SLC 5/05 processors, supporting incremental, absolute, and speed moves. It occupies a single slot and manages absolute position control using a 32-bit register, with twelve input words and twelve output words. For optimal performance, it is recommended to install the 1746-HSRV in Slot 1 or the lowest numbered I/O slot, and up to twelve HSRV modules can be installed in a single rack.
