ABB 216EA62 Analog Input Unit A/D Converter

Product Description

• The ABB 216EA62 is a high‑precision analog input module designed for integration with ABB protection and control systems, such as the REG216 generator protection system.

• It provides real-time digitization of field analog signals, enabling accurate system monitoring in critical applications like generator protection, power plants, and industrial control systems.

• Built to withstand harsh industrial environments, the module has a robust design, good thermal tolerance, and electrical isolation between channels.

• Mounts in a standard ABB rack system and occupies two rack divisions, making it modular and easy to install in ABB protection relay racks.
