Product Details

The 216EA61b HESG448230R1 is analog input processor board for ABB REC216 generator protection and control system.

This board serves as key analog front‑end acquisition component of REC216 protection system. It receives conditioned voltage and current signals from 216GW61 input transformer module, and converts analog quantity into digital data through built‑in high‑speed ADC unit.

Processed digital data is transmitted to main processor via parallel bus for protection algorithm calculation, realizing real‑time monitoring and fault judgment for generator and transformer equipment.

Each signal channel adopts galvanic isolation design, effectively restraining electromagnetic interference from power plant site and improving sampling stability.

On‑board hardware self‑diagnosis function can detect channel over‑range, signal abnormality and board fault, and output corresponding alarm information.

Conformal coated circuit board adapts to harsh power‑industry working environment.

Standard plug‑in rack structure supports convenient on‑site maintenance and replacement.

It is widely used in overhaul and renovation projects of thermal power and hydropower generator‑transformer set protection systems.

It is important spare hardware for protection cabinet maintenance, analog sampling loop debugging and defective 216EA61b board replacement.
