ABB – NTAC‑02 – Pulse Encoder Interface Module, 24 V DC, 7.5 W / 300 mA

The ABB NTAC‑02 is a pulse encoder interface module—an accessory option/SP kit designed to connect incremental encoders (ABZ signals) to ABB frequency converters (e.g., ACS600). It provides selectable 15 V or 24 V encoder supply and interfaces encoder feedback into the drive’s digital control inputs.

Key Features:

• Manufacturer: ABB (Asea Brown Boveri)  

• Model / P/N: NTAC‑02 (also known as NTAC‑02‑KIT, 58976008)  

• Function: Encoder pulse interface module for pulse-to-drive integration  

• Power & Supply: 24 V DC ±10%, 7.5 W, 300 mA; jumper-selectable 15 V or 24 V encoder supply  

• Inputs: Channels A, B, Z with shielded encoder cable support; up to 100 kHz pulse rate  

• Connectivity: Plug-in accessory to ABB frequency converters / drives

• Compatibility: ACS600 and other ABB drives requiring pulse encoder interface; NTAC‑01 and NTAC‑02 are not interchangeable
