GE IS400TBCIH2C

الوصف

The GE IS400TBCIH2C is a Contact Input with Group Isolation Terminal Board used in the Mark VIe and Mark VIeS series of control systems. This board serves as the critical interface between the controller and up to 24 dry contact inputs from field devices.

Key Features and Functionality

The IS400TBCIH2C is designed for high-density contact input applications where signal integrity and noise immunity are essential. Its key feature is group isolation, which prevents interference and crosstalk between different input channels, ensuring each signal is processed accurately.

• Input Channels: The board accepts 24 dry contact inputs, which are wired to two separate barrier-type terminal blocks. These inputs are used to monitor on/off signals from various devices, such as switches and relays.
• Noise Suppression: The module includes internal noise suppression circuitry. This helps protect against electrical surges and high-frequency noise, which can cause false triggers or misinterpretation of input data in harsh industrial environments.
• System Integration: The board works in tandem with a compatible I/O pack, such as the PDIAH1B, to send input data to the main controller. It supports simplex, dual, and TMR (Triple Modular Redundant) applications.
• Field Wiring: The terminal blocks are designed to accommodate wires up to #12 AWG, providing flexibility for different wiring needs. A shield strip is also provided to ground the chassis and protect against electromagnetic interference.
