Allen-Bradley 160-BA04NSF1 Programmable Logic Controller Module

Allen-Bradley 160-BA04NSF1 is a 2 HP Smart Speed Controller (SSC) from the Bulletin 160 family, designed to deliver precise variable-frequency control of small AC motors in 380–460 V three-phase service. This NSF1 variant is part of the Analog Signal Follower lineup and is commonly specified for applications such as conveyors, fans, and pumps where smooth acceleration, deceleration, and speed adjustment are important. The unit is rated for about 4.0 A and is intended for chassis-mount installation in legacy Rockwell Automation systems, providing a compact drive option when a full-size VFD would be unnecessary. The 160 SSC family typically includes a front-panel Ready/Fault indication feature to simplify fault diagnosis in harsh industrial environments. By offering straightforward analog or preset speed control within a compact footprint, the BA04NSF1 enables reliable, energy-efficient motor drive with familiar Rockwell-style configuration and diagnostics for ongoing maintenance and integration with existing control architectures.
