Energy Storage and Brownout Protection Performance

The GE IS200VTURH1A IS200VTURH1ADE stores substantial energy for critical hold-up. Its fourteen capacitors provide 6,580 µF of total capacitance. This storage keeps the processor running for 55 milliseconds after a power loss. As a result, the board completes safety shutdowns without data corruption.

Role Within the Mark VI Speedtronic System

You will typically find the GE IS200VTURH1A IS200VTURH1ADE in the main processor slot of the rack. It communicates with all I/O boards via the VME backplane. Moreover, this board supports triple-redundant configurations for high availability. Its eight analog inputs accept signals from speed probes and thermocouples.

Installation and Configuration Guidelines

Use the GE IS200VTURH1A IS200VTURH1ADE as a direct replacement for older VTUR revisions. Always power down the entire rack before inserting or removing this board. The 96-pin connector aligns with standard VME keying guides. This board requires firmware loading through the auxiliary port. Simply slide it into the chassis and tighten the injector/ejector handles.
