Functional description
The GE IS200ESELH1AAA Exciter Collector Board serves as the central signal aggregation and
distribution hub for GE’s EX2100 excitation control system, dedicated to consolidating, conditioning,
and routing critical analog and discrete signals between field devices (e.g., current transformers,
voltage transducers, breaker contacts) and core EX2100 modules (e.g., regulators, I/O interfaces,
selector boards). Its primary function is to streamline signal flow: it collects raw field signals—
including generator field current/voltage feedback (from CTs/PTs), breaker status signals
(open/closed), and excitation system interlock signals—and processes them via built-in filtering (to
reduce EMI/RFI noise) and isolation (to prevent ground loops). The board then distributes the
conditioned signals to target EX2100 modules (e.g., sending field current data to the IS200DSPX
regulator for closed-loop control, and breaker status to the IS200ESELH2A selector board for failover
logic). It also supports bidirectional signal exchange: receiving control commands from the regulator
(e.g., field current adjustment) and transmitting them to field actuators (e.g., SCR triggers). Equipped
with real-time diagnostic capabilities, the board monitors signal integrity (e.g., detecting open CT
circuits) and communicates fault data to the EX2100 HMI via the EISB bus, with front-panel LEDs for
quick status verification (e.g., green = normal signal, red = signal loss). Designed with an IPC-CC-830B
Class 3 conformal coating and ruggedized terminal blocks, it operates reliably in harsh industrial
environments (e.g., power plant dust, temperature fluctuations) and fits seamlessly into EX2100 racks
for plug-and-play integration.
