This storage smooths out voltage spikes from inductive field loads. Furthermore, the suppression diodes clamp surges at 600 V, protecting sensitive rack electronics.

Role Within the EX2100 Excitation System

You will typically find the GE IS200EXHSG4A IS200EXHSG4AEC mounted near the exciter field output. It connects to the main rack via two shielded ribbon cables. Moreover, this board supports both AC and DC field wiring types. Its twelve terminal blocks accept up to 14 AWG stranded or solid copper wire.

Installation and Wiring Guidelines

Use the GE IS200EXHSG4A IS200EXHSG4AEC as a direct replacement for older EXHSG revisions. Always disconnect the main exciter supply before terminating any wires. This terminal board uses standard slotted screw terminals for reliable connections. It requires no configuration jumpers or software setup. Simply secure the board with four mounting screws and route your field cables through the bottom entry.
