IS200VPROH1BCC

Product Description

The IS200VPROH1BCC model serves as either a Turbine Protection or Turbine Emergency Trip Module, and its interactions depend on its application. When utilized as a Turbine Protection Module, it interfaces with a TPRO board, whereas as a Turbine Emergency Trip Module, it interacts with a TREG module. An Ethernet connection facilitates IONet communication between the VPRO Module and other control modules when connected to the TPRO module.

When the IS200VPROH1BCC model is paired with a TPRO board, they form a self-sufficient emergency over speed protection system. On the other hand, when coupled with a TREG module, the VPRO module takes full control of the TREG board. The maximum number of TREG boards that can be used with the VPRO board is two, limiting the trip solenoid circuits to six.

For testing and programming purposes, the IS200VPROH1BCC board features a VME interface that allows it to be used in a VME rack. However, if connected to the Backup Protection Module, the backplane is neutralized to eliminate continuity between the three control module sections.

The VPRO board primarily relies on an onboard power supply to generate twenty-eight and five volts of direct current from the cabinet PDM's one hundred twenty-five volts of direct current. If integrated into a TMR system, three power supplies are utilized, leading to increased reliability.
