The IS200TVBAH2AAA board is marketed as a Vibration Input Monitoring Board. This model is used with volts of direct current rather than volts of alternating current, there is no negative VDC power supply, and the only power supply for this model is a positive twenty-eight volts of direct current. This model can be utilized in either TMR (Triple Modular Redundant) or Simplex Systems. When the module is being used with a TMR-based architecture such as the Mark VI Series it is made up of power supplies, IONets, and three independent and separate Control Modules.
The physical components of the IS200TVBAH2AAA board consist of seven sub-D pin connectors, two terminal strips, three female plug connectors, and fourteen one-pin connectors. The sub-D connectors have different pin quantities, one connector has nine pins, while half of the remaining six are twenty-five pin connectors, with the remaining three thirty-seven pin connectors. The three thirty-seven-pin connectors which are located close to the outer edge of the board are labeled JR1, JS1, and JT1, the remaining four connectors are labeled JA1, JB1, JC1, and JD1.
As mentioned above the IS200TVBAH2AAA board has two terminal strips/blocks, these two terminal blocks are located on the edge of the board. These two terminals have the ability to accept fourteen sensor inputs. Each terminal block has twenty-four terminals that can use #12 AWG wires. The two terminal blocks are labeled TB2 and TB1.
The communication methods for the TVBA model are either IONet or the Unit Data Highway. The Unit Data Highway is an Ethernet-based LAN that can communicate with multiple other systems produced by General Electric such as the EX2000 Generator Excitation Controls, HMIs, Static Starters, and more.
