Product Overview

• Part No: 216EA61b, Alternative Code: HESG448230R1/G
• Brand: ABB

• Category: Analog Input Module216EA61b is a high-performance analog signal acquisition module developed for ABB REG216 protection platform and substation automation systems. It collects voltage, current signals from transformers and transmitters, converts analog signals into digital data and transmits to main processing unit via internal bus. Adopting high-precision ADC sampling and channel galvanic isolation design, it ensures stable signal acquisition under strong electromagnetic interference environment. The module serves as an essential front-end signal collection component for generator and transformer protection, widely used as replacement spare part for power plant and substation equipment maintenance.
