The IS200VPROH1BCD is a board component for the Mark VI Speedtronic system. This board is part of the turbine protection system.
The IS200VPROH1BCD is built with an on-board power supply. From this, the board generates 28VDC/5VDC via the 125VDC power supplied by the cabinet PDM. The IS200VPROH1BCD works in conjunction with two other boards (TREG and TPRO). The TREG board is completely controlled by the IS200VPROH1BCD.
The IS200VPROH1BCD offers several diagnostic capabilities via its front faceplate. These are read from the LED indicators located within the faceplate. Normal run condition will have a flashing green light. A Fail condition will light a solid red LED. A third STATUS LED will light up as orange if diagnostic checks need to be made. This includes faults within the trip relay driver or Economizer relay driver or associated contact feedbacks, a solenoid voltage issue, or issues with high and low limits on any analog inputs.
Other components within the front faceplate beyond diagnostic LEDs include D-shell connectors, a 3-position power plug, and an IONet connector. The faceplate is doubly wide to protect the two stacked boards behind it along with the tall heat sink that is mounted to the top board. Other components on these boards include four individual backplane connectors, various plug connectors, and surface wire connections, integrated circuits, and diodes, capacitors, resistors, and transistors.
For detailed information about how to properly install, maintain, or handle the IS200VPROH1BCD, please refer to publications provided with your OEM purchase like manuals, data sheets or series user guides. These will also include important information on safety precautions.
