GE IS200SRTDH2ACB RTD Input Terminal Board

The GE IS200SRTDH2ACB, also cataloged as the IS200SRTDH2ACB RTD Input Terminal Board, operates as a dedicated hardware component for temperature sensor signal acquisition and conditioning within Mark VIe control platforms.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

The IS200SRTDH2ACB module manages backplane bus communication velocity by facilitating the conversion of resistance temperature detector (RTD) analog inputs into digital signals for processing by the I/O pack. The board maintains deterministic signal integrity, ensuring that temperature data remains synchronized with the controller's scan cycle. Firmware flash compatibility is governed by the associated I/O pack, which monitors the terminal board's status and ensures the validity of sensor readings. I/O density scaling is supported through standard terminal block arrangements, providing a localized interface for multiple RTD channels while isolating sensitive signal paths from high-power electromagnetic interference within the control cabinet.

Frequently Asked Questions

Q: Is the IS200SRTDH2ACB board hot-swappable during system operation?

A: No. Replacement requires the associated I/O pack to be de-energized to prevent current spikes or potential damage to the RTD input circuitry during the removal or installation process.

Q: How is signal shielding handled on the IS200SRTDH2ACB?

A: The board provides dedicated terminals for sensor shield termination. Shields must be connected to the cabinet ground bus at the terminal board to minimize noise pickup and maintain measurement accuracy.

Field Installation Guidelines

1. Mounting: Install the board in a clean, dry location within the control cabinet. Ensure the mounting surfaces are free of debris to prevent mechanical stress on the printed circuit board.
2. Wiring: Terminate RTD leads to the terminal blocks according to the system wiring diagram. Ensure that 3-wire RTD configurations are correctly mapped to provide lead-resistance compensation.
3. Grounding: Bond the board chassis to the cabinet ground using the designated earthing points. Verify that the shield termination strip has a low-impedance path to the system ground.
4. Environment: Verify that ambient temperatures remain within specified industrial operating limits. Prevent exposure to condensation or corrosive environments that could degrade signal terminal contacts.
5. Verification: Prior to system integration, use a calibrated resistor simulator to verify the input channel accuracy for each RTD point, confirming that the digital value reported by the controller matches the input resistance.
