GE IS200STCIH6A Simplex Contact Input Terminal Board

GE IS200STCIH6A Contact Input Terminal Board

Configured for simplex contact input acquisition in Mark VIe distributed control systems, the GE IS200STCIH6A (IS200STCIH6A Contact Input Terminal Board) provides direct electrical interfacing for 24 dry‑contact channels stimulated at nominal 24 VDC, 48 VDC, or 125 VDC, with integrated suppression for surge and high‑frequency noise.

Suffix Breakdown & Model Matrix

The provided documentation does not define any suffix variants or model matrix for IS200STCIH6A. The board is treated as a single, fixed hardware configuration within the Mark VIe platform.

Hardware Specifications

Backplane Bus Communication Velocity Licences

As a GE industrial control module, the IS200STCIH6A participates in deterministic Mark VIe I/O acquisition cycles. The PAIC I/O pack communicates through a D‑type connector and forwards contact state changes over EtherNet/IP deterministic networks to the controller. The board’s 24‑channel density aligns with I/O density scaling across Mark VIe cabinets, while its surface‑mount design maintains compatibility with firmware flash compatibility requirements for PAIC modules. Noise suppression at each input ensures stable propagation timing even under high‑frequency interference.

Frequently Asked Questions

Q: Can the IS200STCIH6A be hot‑swapped during operation? A: No. The board is mechanically mounted and directly wired; all circuits must be de‑energized before removal.

Q: Does the PAIC I/O pack require configuration changes when replacing the board? A: No. The PAIC automatically detects the terminal board through the D‑type interface. Only wiring verification is required.

Q: How does the board handle high‑frequency noise on contact inputs? A: Each channel includes suppression circuitry that filters surge and high‑frequency disturbances before the signal reaches the PAIC pack.

Field Installation Guidelines

• Mount the board on a DIN‑rail carrier or sheet‑metal assembly using the provided insulator.
• Use #18 AWG wiring for contact inputs unless cabinet standards specify otherwise.
• Terminate shields on the designated bracket to prevent ground loops.
• Maintain separation between contact wiring and high‑energy conductors to reduce induced noise.
• Verify correct seating of the D‑type connector to ensure stable Ethernet communication through the PAIC pack.
• Inspect terminal screws for proper torque after installation to avoid intermittent contact states.
