IS200VAOCH1B is an Analog Output Board developed by GE. The Analog Output Board is in handle of 16 analog 20 mA outputs. These outputs are connected to the Analog Output Terminal Board via two terminal blocks (TBAO). Cables with molded plugs link the terminal board to the VME rack, which contains the processor board. It receives digital data from the controller through the VME backplane and converts them to analog output currents before sending them to the TBAO.

Information module IS200VAOCH1B
Features
On the terminal board, the actual output current is measured and passed back to VAOC, where it is managed.
Control signals are fanned into the same terminal board from three VME board racks R, S, and T in TMR applications.
TMR requires six cables to support all 16 outputs. Each final current output is the median select of the three currents in the three VAOCs, and each has this median select circuit.
Cable connections to the TBAO terminal boards are established at the lower J3 and J4 connectors on the VME rack. To secure the cables, they are latching connections.
Installation
Turn off the VME I/O processor rack.
Insert the VAOC board and use your hands to press the top and bottom levers in to seat the edge connectors.
Tighten the captive screws on the front panel’s top and bottom.
Start the VME rack and look at the diagnostic lights on the front panel.
Operation
The VAOC has 16 analog 0-20 mA outputs. The D/A converter and driver that generates the regulated currents are housed in the VAOC.
The voltage drop across a resistor on the terminal board is used to calculate the output current.
Product Description
The IS200VAOCH1B is an Analog Output PCB created as a component for the Mark VI system. The Mark VI was one of the last gas/steam turbine management systems released by GE as part of their “Speedtronic” line, which had been their premier turbine management line for over three decades. The Mark VI includes diagnostic checking for both hardware and software, time synchronization control options, programmable maintenance tools, and Ethernet communications.
The IS200VAOCH1B is mounted in the VME rack. The board receives digital values from the controller over the rack’s backplane. These are converted to analog output currents and sent to the IS200VAOCH1B’s associated terminal board (usually a TBAO or DTAO board.) The output current is measured on this board and then returned to the IS200VAOCH1B for control. It is important to note the IS200VAOCH1B is an early generation (original) board that can only support load resistances up to 500 Ω. If higher resistance is needed, please refer to our listings for IS200VAOCH1C boards.
The IS200VAOCH1B is built with multiple connectors, including two backplanes. Other connectors on the board are designed with conductive dots and traces. The board is populated with two lines of relays, sixteen in all. Each relay includes a relay diagram. The PCB is built with dozens of integrated circuits; these include oscillating chips, SRAM chips, and FPGAs. The board uses capacitors, resistors, and diodes of various size and made of several materials.
The front panel of the IS200VAOCH1B is a single slot faceplate. It has three LED components inserted into its surface. The LEDs are labeled run, fail, and status.
Compatibility
The VAOC board and accompanying terminal boards come in two generations. All VAOC iterations up to and including VAOCH1B are considered to be the original VAOC. These boards can sustain up to 500 W of load resistance at the end of 1000 feet of #18 wire while driving 20 mA outputs. For optimal operation, this generation of board needs a terminal board TBAOH1B or earlier. Additionally, they are compatible with all DTAI terminal board revisions.
Each analog current output in a TMR system is fed by the combined currents from the three VAOCs. With the help of a series resistor that feeds a voltage back to each VAOC, the total output current is measured. The three currents’ median value, as determined by voting, is the output. The other two pick up the current to the right value if one output fails.
In the event of a circuit malfunction that cannot be resolved by a CPU order, the circuit is shut down by opening the contacts on the shutdown relay. Only when setup for TMR operation is this isolation feature usable.

Reviews For IS200VAOCH1B
The IS200VAOCH1B, while a low failure rate printed circuit board, has extremely limited availability on the market currently. The VME Analog Output Card IS200VAOCH1B is a repairable board but due to continued parts availability that option is often costly. Functionally, the IS200VAOCH1B does not require significant expertise to install in speedtronic turbine control systems and is more or less plug and play in most applications.
