Product Description

The IS200VATFG1AAA is a MKVI GE PCB (printed circuit board) component.  The Mark VI is part of the Speedtronic series of industrial steam/gas turbine management control that began with the release of the MK I in 1969 and has continued for several decades on through the 2000s with systems like the Mark VI and Mark VIe.  The Mark VI offers a whole system solution to turbine management, including integrated control, protection, and monitoring that can be designed with either Simplex or Triple Redundant set-up, depending on the size, complexity and needs of the turbine system.   Most of the control processes for the MKVI occur within the central Control Module, which is available as a 13- or 21- slot VME card rack system. 

The IS200VATFG1AAA is used as a Voltage Attenuator Feedback Board that provides weakening (attenuation) of either ac or dc bridge voltages of Innovation Series drives.  The board achieves this through two sets of identical strings of series-connected precision resistors with input connections (stab-on connectors) at places along the string to allow for the accomodation of a range of voltages.   7000 V peak is the max attenuator input.  

The IS200VATFG1AAA is built with eight stab-on connectors, two fiber-optic transmitter connectors, five TP test points, two plug connectors, and one LED indicator (PSOK.)   The board has a single transformer and one heat sink component, as well as several integrated circuits.  The board uses electrolytic, ceramic, and poly vinyl capacitors. Resistors are those previously mentioned above, as well as several metal film resistors.  The board also has a single resistor network array.
