GE IS200TGENH1A Terminal Board Generator Monitor

Part Number IS200TGENH1A Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI Function Module Availability In StockIS200TGENH1A is a Terminal Board Generator Monitor developed by GE under the Mark VI series. The Generator Monitor (TGEN) terminal board communicates with the VGEN processor to monitor the three-phase voltage and currents of the generator, as well as to calculate the three-phase power and power factor. 

 VGEN provides the PLU and EVA capabilities for large steam turbine applications by utilizing fast-acting solenoids situated on the TRLY terminal board. The TGEN in the Mark VI system collaborates with the VGEN processor and supports simplex and TMR applications. A single cable links one TGEN to the VGEN. TGEN connects to three VGEN boards through three distinct wires in TMR systems. IS200TGENH1A Operation TGEN's two- and three-phase PT inputs, as well as three- and one-phase current transformer CT inputs, are monitored by VGEN. 

Four analog inputs can be adjusted for 4-20 mA or 5, 10, 20 V dc using jumpers. The phase of the input signals is checked using test points on the generator and bus voltages and currents. VGEN converts signals and calculates power, power factor, and frequency. To verify the phase in the field, test points are provided for all PT and CT inputs. Three single-phase CT inputs with a continuous normal current range of 0 to 5 A are provided. TGEN's CTs are magnetically isolated. CT terminations are non-pluggable terminal blocks with captive lugs that accept wires up to #10 AWG. 

The four analog inputs can accept 4-20 mA or 5-10 V dc signals. A +24 V dc source is available for all four circuits, each with its own current limit. The 4-20 mA transducer can be connected to either the turbine control's +24 V dc source or as a self-powered source. Installation Terminal block 1 is wired with analog current and potential transformer (PT) inputs. The current transformer (CT) is connected to special terminal blocks TB2, 3, and 4, which are not removable. This safeguards against an open CT circuit. J1A and J1B set the desired input current or voltage on analog inputs 14. IS200TGENH1A Characteristics Inputs to VGEN and TGEN Two 3-phase generators and bus PTs Three 1-phase generators CTs Four analog inputs Generator and bus voltages 115 V RMS nominal The nominal frequency is 50/60 Hz. Magnetic isolation of up to 1,500 V RMS (loading less than 3 VA) Less than 3 VA of input loading per circuit Generator current inputs The normal current range is 0 to 5 A, with an over-range of up to 10 A. 

The nominal frequency is 50/60 Hz, while the frequency range of interest is 45 to 66 Hz. Magnetic isolation of up to 1,500 V RMS Less than 0.5 input load per circuit Physical Characteristics Weight: 4.00 lbs Dimensions: 15.00 x 9.00 x 3.00 Diagnostics Diagnostics check the input signal for a high/low (hardware) limit and a high/low system (software) limit. The software limit check can be changed in the field. Voltage inputs have open wire detection, and relay drivers and coil currents are monitored. The terminal board's connectors JR1, JS1, and JT1 each have their own ID device that is interrogated by the I/O board. The ID device is a read-only chip that contains the serial number, board type, revision number, and plug location of the terminal board. Configuration Jumpers are used to configure the terminal board. The available jumpers are as follows: Jumpers J1AJ4A select either current or voltage input. Jumpers J1BJ4B determine whether the return is connected to common or left open.

Configuration

The configuration of the terminal board involves the utilization of jumpers, allowing for customizable settings to suit specific input requirements. Here's an expansion on the available jumper choices:

Jumper Functions: Jumpers J1A through J4A serve the purpose of selecting between current input or voltage input. These jumpers allow users to determine the type of input for each corresponding terminal or channel on the board. Jumpers J1B through J4B play a crucial role in deciding whether the return path is connected to common or left open. This configuration choice influences the grounding or isolation of the return path for each specific input channel.

Location and Configuration Guide: The exact placement and configuration of these jumpers are specified in the installation diagram provided with the terminal board. The diagram illustrates the precise locations and settings of these jumpers, guiding users on how to configure them based on their intended input preferences.
Jumper Choices and Settings: J1A through J4A jumpers enable users to specify whether the input signal for each channel should be received as a current input or a voltage input. This choice is essential in aligning the board's input method with the nature of the connected sensors or devices. J1B through J4B jumpers determine whether the return path for each channel is connected to the common ground or is left open. This configuration decision affects the grounding scheme or isolation of the return path, providing flexibility in system design and electrical connections.

Application Specificity: The specific choice of jumper settings depends on the application's requirements, the type of sensors or devices connected to the terminal board, and the desired electrical configuration for the inputs.
