Description

roduct Overview

The 216VE61B HESG448230R1 belongs to the classic ABB REG216 generator & transformer modular protection system. It is the external excitation / auxiliary power module, supplying stable reference excitation and auxiliary supply to the whole REG216 rack and companion cards: 216EA61B analog input, 216DB61 binary trip, 216VC61/VC62 processing unit, 216GE61 relay input unit, widely used on thermal power generator sets and block transformer protection cabinets.

Note: There is a common part number mix-up:

• 216VE61B: Excitation supply card (your query)
• 216EA61B HESG448230R1: Analog input sampling card (often confused)
• The alternate drawing number HESG324258R11 / HESG324257/E also refers to this 216VE61B variant
