Functional Description

IS200ECTBG1ACB is an Exciter Contact Terminal Board developed by GE. It is a part of the EX2100 control system. The terminal board serves as a component within the EX2100 Excitation Control system, facilitating excitation contact outputs and inputs. ECTB terminal board is available in two distinct versions to accommodate different control configurations. ECTBG1 is utilized in redundant control setups. ECTBG2 Solely employed in simplex control configurations.

Features

• Output Functions: Each board incorporates two trip outputs responsible for activating a customer lockout, under the supervision of the board. Additionally, four general-purpose Form-C contact outputs are included, also controlled by the board.
• Input Functions: Six auxiliary contact inputs receive power (wetted) using a 70 V dc source and are monitored. The 52G and 86 G contact inputs are powered from a 70 V dc source and are similarly monitored.
• Power Supply: In redundant control setups, power is sourced from both the M1 and M2 controllers.

Contact Inputs

• Functionality in Simplex and Redundant Configurations:While the purposes of contact inputs remain consistent across simplex and redundant control setups, their distribution and connectivity vary based on the control architecture. In redundant control configurations, the inputs are distributed to the M1, M2, and C controllers for enhanced redundancy. Conversely, in simplex control, only the M1 controller is engaged.
• Auxiliary Contact Inputs: ECTB facilitates six auxiliary contact inputs provided by the customer, which are powered and monitored using a 70 V dc supply sourced from plugs J13M1 and J13M2. These inputs are resistor-isolated and supplied to the contacts, with the wetting voltage ranging from 63 to 84 V dc. The state of each auxiliary contact is continuously monitored. A red indicating LED reflects the status, and the signal is fanned out to controllers M1, M2, and C for comprehensive monitoring and control.
• 52G and 86G Contacts: A contact from 52G is similarly monitored using the 70 V dc excitation method, with its status indicated by a dedicated red LED. Another contact originating from 86G is wetted with a nominal 70 V dc voltage. Its state is actively monitored by controllers M1, M2, and C, ensuring comprehensive oversight and control over system operations.

Application Data

• Trip and General-Purpose Relays: K1 and K2 serve as trip relays within controllers M1, M2, and C, playing a pivotal role in activating protective measures in response to predefined conditions or faults. Additionally, K1GP through K4GP are designated as general-purpose relays, offering versatile functionality for various control and monitoring tasks as required by the system.
• Terminal Blocks: Terminal blocks TB1 and TB2 serve as connection points for wiring and cable terminations. They are securely held in place with two screws, allowing for easy installation and maintenance procedures.
• Connectors: The system utilizes three 25-pin sub-D connectors, namely J405, J408, and J415, which facilitate the connection of cables to the EBKP backplane. These connectors establish communication links with the EMIO boards housed within controllers M1, M2, and C. Moreover, plugs J13M1 and J13M2 are employed to bring in a 70 V dc power supply for contact wetting from the M1 and M2 power sources, ensuring proper functioning of contact-related components.

Frequently Asked Questions

What is IS200ECTBG1ACB?
It is an exciter contact terminal board developed by GE under the EX2100 series.

How many versions of the board are available, and what are their differences?
There are two versions- ECTBG1 and ECTBG2. ECTBG1 is utilized exclusively in redundant control setups, whereas ECTBG2 is designed for simplex control configurations.

What are the main features of the terminal board?
Each board includes two trip outputs responsible for driving a customer lockout, which is under the control of the EMIO board. Additionally, there are four general-purpose Form-C contact outputs that are also controlled by the EMIO board.

How is power supplied to the board in different configurations?
In redundant control setups, power is sourced from both M1 and M2 controllers. In simplex control setups, power comes only from the M1 controller.

How are the 52G and 86G contacts monitored?
The 52G and 86G contacts are powered with a 70 V DC supply and monitored by controllers M1, M2, and C. A red LED indicates their status for real-time monitoring.

What role do the relays play?
The board includes trip relays (K1 and K2) that activate protective measures in response to system faults. It also includes general-purpose relays (K1GP to K4GP) that handle versatile control and monitoring tasks.

What terminal blocks are used for wiring?
Terminal blocks TB1 and TB2 are used for secure wiring connections, held in place by screws for easy installation and maintenance.
