TECHNICAL SPECIFICATIONS FOR GE - IS200TBAIH2C

IS200TBAIH2C is an Analog Input/Output Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Turbine Control Systems. The Analog Input/Output (TBAI) terminal board supports 10 analog inputs and 2 outputs. The 10 analog inputs accommodate two-wire, three-wire, four-wire, or externally powered transmitters. The analog outputs can be set up for 0-20 mA or 0- 200 mA current. Inputs and outputs have noise suppression circuitry to protect against surge and high-frequency noise. TBAI has three DC-37 pin connectors provided on TBAI for connection to the I/O processors. Simplex applications are supported using a single connector (JR1). TMR applications are supported using all three connectors. In TMR applications, the input signals are fanned to the three connectors for the R, S, and T controls. TMR outputs combine the current of the three connected output drivers and determine the total current with a measuring shunt. TBAI then presents the total current signal to the I/O processors for regulation to the commanded setpoint.

INSTALLATION:

Connect the input and output wires directly to two I/O terminal blocks mounted on the terminal board. Each block is held down with two screws and has 24 terminals accepting up to #12 AWG wires. A shield terminal attachment point is located adjacent to each terminal block. TBAI can accommodate the following analog I/O types:

Analog input, two-wire transmitter

Analog input, three-wire transmitter

Analog input, four-wire transmitter

Analog input, externally powered transmitter

Analog input, voltage 5 V, 10 V dc

Analog output, 0-20 mA

Analog output, 0-200 mA

OPERATION:

TBAI provides a 24 V DC power source for all the transducers. The inputs can be configured as current or voltage inputs using jumpers (J#A and J#B). One of the two analog output circuits is 4-20 mA and the other can be configured as 4-20 mA or 0- 200 mA. The following table displays the analog I/O capacity of TBAI. Each 24 V dc power output is rated to deliver 21 mA continuously and is protected against operation into a short circuit. Transmitters/transducers can be powered by the 24 V dc source in the control system, or can be independently powered. Jumper JO selects the type of current output. Diagnostics monitor each output and a suicide relay in the I/O controller disconnects the corresponding output if a fault cannot be cleared by a command from the processor.
