FAQ
Q1: What is the IS200TRROH1B?
A1: It is a relay output terminal board used in GE Mark VI turbine control systems to provide discrete switching outputs for field devices.
Q2: What is its main function?
A2: It converts control logic from Mark VI controllers into physical relay outputs used for sequencing, interlocks, and auxiliary system control.
Q3: Is it a protection (trip) board?
A3: No. It is mainly used for control and sequencing, not primary turbine trip protection.
Q4: What type of outputs does it provide?
A4: It provides Form C relay outputs for switching industrial control circuits.
Q5: Does it execute logic?
A5: No. All logic is executed by Mark VI controllers; this board only performs switching.
Q6: What are typical applications?
A6: Turbine start/stop sequencing, auxiliary equipment control, interlocks, and general relay output expansion.
Q7: Is it still in production?
A7: No. It is a legacy GE Mark VI component, typically sourced from surplus or refurbished industrial automation markets.
