ABB MIM4140 1MRS050469 1MSC980130 Transformer Module
I. Product Overview
The ABB MIM4140 is the core analog signal processing module – the Transformer Module (also known as CT/PT signal transformer sampling board) – inside the ABB REF 54_ / REM 54_ / RET 54_ series numerical protection relays (feeder terminals, machine terminals, transformer terminals). This module is responsible for isolating, transforming, and sampling the secondary signals from field current transformers (CT) and voltage transformers (PT), providing accurate analog signal inputs for the measurement and protection functions of the protection relay.
The module hardware number is 1MSC980130 REV:B, order number is 1MRS050469, manufactured by ABB Industrial Oy (Finland), with certification level Certification Level 1. The module incorporates 9 matching transformers, including 5 current input channels (CT1-CT5) and 4 voltage input channels (VT1-VT4), supporting 1A/5A rated current and standard PT secondary voltage inputs. The input circuit and sampling circuit feature 2000VAC electrical isolation, with sampling linearity error ≤±0.5% of full scale, ensuring accurate and reliable signal measurement. Widely used in feeder protection, motor protection, transformer protection and other relay protection devices in medium voltage distribution systems.
