　　Product Description

The IS200HSLAH2A is a GE PCB component created for the Mark VI series. The Mark VI is one of the last of the Speedtronic series created and developed by GE for the management of their heavy-duty turbine systems. It is considered a complete platform solution for the control, protection, and monitoring of gas and steam turbines used for a variety of applications. The Mark VI is designed to be adaptable and scalable, with the ability to add modules as needed to service the complexity of the system. The Mark VI control systems are available in either Simplex or Triple Redundant forms in order to offer the architecture that will best meet the needs of both small applications as well as large integrated systems.(https://www.weikunfadacai1.com/)

 

The IS200HSLAH2A functions as an HS SLR LNK Interface. It has components on both board surfaces. On its top surface, this board is built with two jack inputs/outputs. These are located side-by-side along one short edge of the board. The board has two transformers marked Halo TG 110-EO 50N5. It also has six inductor coils, over 150 resistors, over 100 capacitors, and several transistors. The board is built with over twenty integrated circuits, including an FPGA (field programmable gate array) located at U1. The bottom of the board has an additional two (female) connectors, and additional resistors, capacitors, and transistors. Most components on the board carry a reference designator. The code FA/00 is marked in one corner. The board has multiple conduction sensors built into the board.(https://www.weikunfadacai1.com/)

　　FUNCTIONAL DESCRIPTION:

IS200STAOH2A is a Simplex Analog Output Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in Distributed Control Systems. Compact analog output terminal boards are available, such as the Simplex Analog Output (STAO) terminal board, which is made for flat or DIN-rail mounting. Eight 0-20 mA analog outputs on STAO are powered by the PAOC I/O pack. Similar to the TBAO terminal board, the onboard circuitry and noise reduction are present. The board is equipped with high-density Euro-block style terminal blocks for connecting to the customers’ devices. The board is identified to the I/O processor by an onboard ID chip for system diagnostics. The D-type connector is used to connect the I/O pack, which uses Ethernet to talk to the controller.

 

　　INSTALLATION:

The STAO and a plastic insulator are mounted in a panel or on a DIN-rail-mounted sheet metal carrier. The STAO plus insulator mount can also be attached to a sheet metal assembly that is bolted directly to a cabinet. Driven equipment can be placed up to 300 meters (984 feet) away from the turbine control cabinet and shouldn’t have a resistance greater than 900. There are two varieties of Euro-block terminal blocks:

An unpluggable mount terminal block with 36 terminals is present on STAOH1.

　　A permanently installed terminal block with 36 terminals is present on STAOH2.

As seen in the following diagram, the eight analog outputs are attached directly to the terminal block. For the SCOM connection, there are two screws. Typically, shielded twisted pair (#18 AWG) wires are utilized. An external mounting bracket supplied by GE or the client is used by the I/O cable shield termination. The mounting holes E1 and E2 are for the chassis ground screw connection (SCOM). To save cabinet space, DIN-type terminal boards can be stacked vertically on the DIN rail.

　　OPERATION:

　　Eight analog control current outputs are supported by STAO. The voltage drop across the current sense resistor in the local loop is detected for each output, and the signal is transmitted back to the I/O processor that regulates the current. Each output’s surge is suppressed and high-frequency noise is reduced by filters close to the signal exit point. The D/A converter and drivers that produce the regulated currents are found in the I/O processor.

　　DIAGNOSTICS:

The output current is shown by the voltage drop across a series resistor on the board. A diagnostic alarm (fault) is generated by the I/O processor if either of the two outputs becomes unhealthy.

The I/O controller queries each ID device that each cable connector on the terminal board has to offer. The terminal board serial number, board type, revision number, and the placement of the JR, JS, and JT connectors are all encoded on a read-only chip known as the ID device.

A hardware incompatibility fault is produced when the I/O controller reads this chip and runs across a mismatch.
