GE IS200TCASH1ACB Terminal Board

Configured for signal termination and distribution in Mark VIe control architectures, the GE IS200TCASH1ACB (IS200TCASH1ACB Terminal Board) provides direct physical and electrical execution of analog signal routing and sensor excitation.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

The IS200TCASH1ACB serves as an interface node within the Mark VIe ecosystem, facilitating standardized signal conditioning between field-mounted instrumentation and system I/O packs. The board architecture supports deterministic backplane bus communication velocity, ensuring that analog data acquisition remains synchronized with controller scan cycles. Firmware flash compatibility is managed via the host I/O pack configuration, which defines the scaling and filtering parameters for the 25 input channels. The module supports I/O density scaling through its robust termination layout, allowing for high-integrity signal transmission while minimizing signal degradation over field cabling. The surface-mount technology utilized in the PCB construction maintains consistent electrical impedance, supporting precision analog output regulation from 0 to 20 mA.

Frequently Asked Questions

Q: Does the IS200TCASH1ACB support hot-swapping under load?

A: No. Replacement of the terminal board requires the associated I/O loop to be de-energized to prevent transient currents from damaging the analog output circuitry or the connected field devices.

Q: Is the 24 VDC excitation voltage configurable on a per-channel basis?

A: No. The 24 VDC excitation is common across the designated input channels on the board. Ensure all field instruments connected to these inputs are compatible with the shared excitation voltage.

Field Installation Guidelines

1. Mounting: Secure the board within the cabinet using the provided mounting holes. Maintain adequate clearance from high-voltage AC lines to prevent induced noise on the analog signal paths.
2. Wiring: Terminate field wiring using the designated terminal blocks. Maintain consistent polarity for all analog loops and ensure that cable shields are grounded at a single, low-impedance point to minimize common-mode noise.
3. Loop Resistance: Ensure that the total lead resistance of the field cabling does not exceed 15 Ohm to maintain the accuracy of the 4-20 mA signal transmission.
4. Environment: Verify that the cabinet internal temperature remains within the specified range of 30 deg C to 50 deg C. Provide sufficient airflow to prevent heat accumulation around the board's passive and active components.
5. Verification: Prior to energization, conduct a point-to-point electrical check to verify wiring integrity and polarity. Use the Mark VIe diagnostic tool to confirm that all 25 analog inputs are correctly registered by the system.
