Specifications

Description

IS200VCRCH1BBB is a discrete input/output board developed by GE. It is a part of Mark VI control system. The Contact Input/Relay Output Board is a module designed for managing numerous discrete input and output signals within a VME-based system. This narrow module is integral to control systems that require robust input/output handling capabilities.

Applications

Thermal Power Plants: Widely used in power generation units equipped with GE Frame 6, 7, and 9 series gas turbines and steam turbines.

Combined Cycle Power Plants (CCGT): Used to manage the interlocking control system between the waste heat boiler (HRSG) and the steam turbine.

Oil & Gas Refineries: Used to control the logic interlocks of large centrifugal compressor units and captive power plants.

Nuclear Power Plants: Used in the non-safety-grade conventional island control system, responsible for the switching logic of auxiliary equipment.

Large Petrochemical Plants: Used in power centers requiring high-reliability relay protection, such as cracking units and ammonia synthesis units.

Steel Mills: Responsible for the sequential control of high-power synchronous motor-driven steel rolling production lines and power distribution systems.

Large Paper Mills: Used for the process logic and equipment protection of captive cogeneration units.

Features

1 Inputs and Outputs: Along with its associated daughterboard, the module is capable of handling a substantial number of signals. It accepts up to 48 discrete inputs, which allows it to monitor a wide range of external signals and statuses. In addition to input capabilities, it controls 24 relay outputs. These outputs enable the board to activate or deactivate external devices, such as motors, lights, or other relay-driven equipment.

2 Terminal Boards: The input and output signals are managed through a total of four terminal boards. These terminal boards serve as the interface points where the external wiring connects to the module. The specific terminal boards associated are: TBCI: This board is used to connect the discrete input signals. TRLY: This board is used to connect and control the relay outputs.

3 VME I/O Rack Mounting: The module is designed to mount within a VME I/O rack, which is a standardized hardware platform commonly used for industrial and embedded computing applications. The VME rack provides the necessary infrastructure for power, cooling, and interconnectivity between various modules.

4 Connectivity: The VME I/O rack includes two sets of J3/J4 plugs. These plugs are used for the connection of cables to the TBCI and TRLY terminal boards. The J3/J4 connectors are part of the VMEbus standard, providing a reliable means of communication and power distribution between the module and its associated terminal boards.

Contact Inputs

1 First 24 Inputs: The first 24 dry contact inputs connect to a TBCI (Terminal Board for Contact Inputs), serving as the main interface for signal integration.

2 Inputs 25–48: Inputs 25 to 48 require a second TBCI board, allowing easy expansion while maintaining organized connections.

3 DC Power Provision: The system supplies internal DC power for contact inputs, simplifying wiring and eliminating external power needs.

4 Cables with Molded Plugs: Terminal boards connect to the VME rack via molded-plug cables, ensuring secure, low-interference data transmission to the processor board.

5 1 ms Scanning Rate: Supports fast scanning at 1 ms, enabling precise real-time monitoring in critical applications like turbine control.

6 SOE Recorder: Records all contact changes with 1 ms resolution for accurate event tracking and diagnostics.

7 Contact Chatter Reporting: Detects and reports rapid contact fluctuations, helping identify unstable conditions.

8 Pulse Width Detection: Captures pulse widths as short as 6 ms, ensuring transient events are not missed.
