Core Function

EPSM excitation protection signal terminal board for EX2100 generator excitation system. It collects multiple protection‑related analog and discrete signals from the excitation cabinet, transfers field excitation status signals to the Mark VI main control board through ribbon cable. It provides electrical isolation between field excitation equipment and control rack, reducing ground loop and surge interference impact. It interfaces core protection conditions such as over‑excitation, under‑excitation and loss‑of‑excitation, provides raw signal basis for excitation limit and protection logic. It applies to simplex and TMR redundant excitation systems, guarantees reliable signal acquisition for generator excitation protection.

Product Details

IS200EPSMG1AED belongs to EPSM series excitation protection signal terminal hardware for GE EX2100 excitation control system.

This signal interface board is installed inside the EX2100 excitation cabinet. Field excitation transformer, relay and sensor signals are connected to its terminal block. After isolation processing, signals are transmitted to VME main controller card via dedicated ribbon cable. Channel‑level isolation effectively suppresses interference generated by high‑power excitation equipment, avoiding disturbance to control system. On‑board LED indicators show real‑time channel working state, convenient for field inspection and fault location. Conformal coated circuit board improves anti‑vibration, moisture‑proof and anti‑electromagnetic‑interference performance, adapts to harsh working environment of power‑plant excitation cabinet. Widely used in gas‑steam turbine generator excitation cabinets for excitation protection signal acquisition.

It belongs to important excitation protection signal spare‑part for EX2100 excitation system, widely used in overhaul and renovation projects of power generation units.

It is important spare hardware for excitation protection loop debugging and defective IS200EPSMG1AED board replacement.
