Allen-Bradley 1201-HJ2 Human Machine Interface

The Allen‑Bradley 1201‑HJ2 Programmer Terminal with Human Machine Interface (HMI) is a handheld operator interface designed to configure and monitor Allen‑Bradley drive systems, combining an LCD display with a keypad and a built‑in digital potentiometer to provide direct user input and feedback. Key specifications include a 12 VDC power supply and a typical current draw around 0.11 A, and a compact form factor that weighs approximately 0.29 kg. It is cataloged in Allen‑Bradley’s drive interface/operator family and is described by distributors as discontinued by the manufacturer. This device functions as a programmer terminal for drive interfaces with HIM capabilities, offering operator input through the keypad and visual feedback on the LCD, and it is used with Allen‑Bradley drive equipment. Part number 1201‑HJ2 is documented in multiple sources as a historical HMI/programmer terminal, now typically found only in surplus, refurbished, or dealer stock.
