Allen-Bradley 160-AA04NSF1 Analog Input Module

The Allen-Bradley 160-AA04NSF1 is a 1 HP analog-signal follower speed controller in the 160-series family, designed for 200–240 V AC three-phase input and offered in an open-style enclosure. The NSF1 suffix identifies its analog signal follower configuration, with the 160-AA04NSF1P1 variant appearing in supplier catalogs as part of this model line. In analog signal follower mode, the module accepts an external analog reference to set motor speed and then drives a connected three-phase motor accordingly. Because it is described as open style, this unit is intended for panel mounting without a traditional enclosure, with installation and safety guidance provided in the accompanying documentation. Distributors listing this model include Radwell, IMS Supply, and DO Supply. The 160-AA04NSF1P1 packaging variant is referenced in catalogs as part of the same series. It is commonly integrated with Allen-Bradley 160-series control architectures for fine-speed control of small three-phase motors in automation tasks in industrial environments.
