Function Description:
IS230TBAIH2C is an analog I/O terminal board manufactured and designed by General Electric as part of the Mark VI series used in GE Speedtronic gas turbine control systems. Supports 10 analog inputs and 2 analog outputs for analog input/output (TBAI) terminal boards. Two wire, three wire, four wire, or transmitters with external power supply can be connected to 10 analog inputs. The analog output can provide current settings of 0-20 mA or 0-200 mA. To prevent surges and high-frequency noise, the input and output contain noise suppression circuits. To connect to the I/O processor, TBAI has built-in three DC-37-pin connectors within the device. Using a single connector, supports simplex applications (JR1). All three connectors are capable of supporting TMR applications.
R. The input signals controlled by S and T are transmitted to three connections in the TMR application. TMR outputs the current of three connected output drivers and calculates the combined current using a measuring shunt. Then, TBAI provides the total current signal to the I/O processor to adjust to the specified set point.
MARK VI System: TBAI supports simplex and TMR applications in Mark * VI systems and collaborates with VAIC processors. VAIC can be linked to one or two TBAIs. TBAI is connected to three VAIC boards in the TMR system.
Installation:
Connect the two I/O terminal blocks installed on the terminal board directly to the input and output lines. Each module has 24 terminals that can accommodate wires up to # 12 AWG and are secured with two screws. There is a shielded terminal connection point next to each terminal block. TBAI can accommodate the following types of analog I/O:
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
Surgery:
All sensors are equipped with a 24V DC power supply provided by TBAI. Jumpers (J # A and J # B) can be used to configure inputs as current or voltage inputs. One of the two analog output circuits can be configured as 4-20 mA or 0-200 mA, while the other can be programmed as one of them. Each 24 V DC power output can continuously provide 21 mA current and prevent short circuits during operation. The transmitter and sensor can be powered separately or by a 24V DC power supply in the control system. The current output type is selected by the jumper JO. The diagnostic function will closely monitor each output. If the fault cannot be repaired through CPU commands, the suicide relay in the I/O controller will disconnect the relevant output.
The IS230TBAIH2C analog I/O terminal board usually refers to a terminal board that can be used for analog signal input and output. It plays a crucial role in many applications, especially when dealing with continuously changing physical quantities such as audio, video, sensors, etc.
This type of terminal board has specific input and output ports for data exchange with external devices. For example, in industrial automation control systems, analog I/O terminal boards can convert analog signals from various sensors into digital signals for use by the control system. At the same time, the digital signals output by the control system can also be converted into analog signals to drive the actuator.
In addition, the IS230TBAIH2C analog I/O terminal board can also be used for temperature control, liquid level monitoring and control, pressure monitoring and alarm systems, and other scenarios. For example, in a temperature control system, an analog I/O terminal board can receive analog signals from temperature sensors and convert them into digital signals for the control system to process, thereby achieving precise temperature control.
Overall, the IS230TBAIH2C analog I/O terminal board has a wide range of applications in industrial automation, control systems, signal processing, and other fields, and is one of the key components for achieving signal conversion and data transmission.
Configuration:
The terminal board is configured with jumpers. Please refer to the installation diagram for the location of these jumpers. The jumper selection is as follows:
Jumpers J1A to J8A can be used to select current input or voltage input.
Whether the circuit is connected to the common terminal or remains open is determined by the routing jumper J1B to J8B.
Use jumper J9A and J10A to select input current between 1 mA and 20 mA.
Whether the circuit is connected to the common terminal or remains open depends on the routing jumpers J9B and J10B.
Adjust output 1 to 20 mA or 200 mA through jumper J0.
