IS200BPIAG1A Product Overview

To put it simply,the GE IS200BPIAG1A(or its equivalent)The IS200BPIAG1AEB is the”pacemaker”and”power manager”of the GE MARK VIe control system.While it doesn’t participate in the control logic,if it fails,the entire MARK VIe cabinet will be depleted—the TCEA master control card,ICC processor,and ACE analog card will all cease to function,causing the gas turbine to immediately trip.

This card efficiently and stably converts the 24V DC control power provided on-site into three voltages:+5V(for digital logic)and±15V(for analog circuits),which are then distributed via the backplane to all cards in the rack.It’s not the primary driver,but without it,the entire control system would be useless.

Where is the GE IS200BPIAG1A used?It’s used in MARK VIe control cabinets for 9E,9F,and 7HA-class gas turbines,large steam turbines,and combined-cycle power plants—tens of thousands of units worldwide.It supports redundant configurations,with two cards operating in parallel to balance the output current and provide a more stable power supply.If one card fails,the other immediately takes over,leaving the system unaware and the turbine operating normally.

This model and the IS200BPIAG1AEB are essentially the same functional module,though they may be from different batches or have minor hardware revisions.However,their performance and interfaces are fully compatible,allowing for field interchangeability.Simply plug and go,worry-free.

Main Features and Advantages

First,let’s talk about the high-power+5V output.The+5V 15A output is higher than the 10A of older systems(such as the Mark V),making it capable of driving more powerful processors and FPGA chips on the Mark VIe platform,meeting the high-computing demands of modern control systems.

Next,let’s talk about the ultra-low voltage ripple.A ripple of≤30mV p-p ensures extremely clean power to the CPU and high-speed digital circuits.A dirty power supply can easily cause high-speed processors to malfunction,freeze,or malfunction.This card’s low ripple is essential for long-term,stable system operation.

It comes with multiple protections:overvoltage(OVP),overcurrent(OCP),short-circuit(SCP),and reverse polarity protection.Got the polarity wrong during on-site wiring?This power card automatically shuts down without burning the internal circuitry.Is a downstream card short-circuited?It automatically limits current or shuts down,preventing other cards from being affected,providing strong fault isolation capabilities.

Electrical isolation(≥1500V AC)effectively cuts off ground loop interference,preventing dirty electricity from on-site from entering sensitive control electronics and protecting the million-dollar TCEA master control card.

Hot-swappable.The MARK VIe system was designed with maintainability in mind.This card supports hot swapping,allowing replacement without downtime,making it a lifesaver for continuously operating power plants.

Finally,let’s talk about redundancy.Two GE IS200BPIAG1A units can operate in parallel,achieving N+1 redundancy or current-sharing output.If one unit fails,the other automatically assumes the entire load,ensuring system continuity.This is a lifesaver for critical gas turbines.
