Introduction
The IS200EROCH1ABB is an emergency relay output module manufactured by GE for Mark VI/VIe control architectures. It serves as a protective interface that converts system logic into hardwired relay outputs for shutdown, trip, or interlock functions. Its stable relay actuation and durable contact design make it a dependable component for turbine protection and high-integrity safety chains.
The board is especially valued in environments where command certainty and response time directly affect operational safety.

Technical FAQs
-
What is the primary purpose of the IS200EROCH1ABB?
It converts logic-level commands into isolated relay outputs used for protection and shutdown functions. -
Does it support redundant architectures?
Yes, commonly used in A/B redundant protection designs. -
Are the relays field-replaceable?
No, the board is replaced as a complete assembly. -
Is it compatible with both Mark VI and Mark VIe?
Yes, it is electrically and mechanically suitable for both. -
Does the module need calibration?
No calibration is required. -
What indicates potential failure?
Relay chatter, stuck contacts, or inconsistent actuation timing. -
Are the relay contacts dry contacts?
Yes, they provide electrically isolated switching. -
Can it handle high-current loads?
No—relays are rated for control-level currents only. -
Is hot-swapping permitted?
No, power must be isolated before removal. -
What is the typical service life of the relay contacts?
Several hundred thousand actuations under normal control loads.
