GE IS200STCIH6A Contact Input Terminal Board

Configured for discrete signal acquisition in Mark VIe distributed control platforms, the GE IS200STCIH6A (IS200STCIH6A Contact Input Terminal Board) provides direct physical/electrical execution of field contact monitoring.

Hardware Specifications

Industrial Control and I/O Density Scaling

The IS200STCIH6A functions as a termination interface for field-level discrete inputs, supporting nominal voltages of 24, 48, and 125 V DC. The board incorporates integrated noise suppression circuitry to protect against transient surges and high-frequency noise inherent in industrial environments. System integration is achieved through Mark VIe or Mark VIeS controller compatibility, utilizing the terminal board's ability to map 24 independent inputs to the associated I/O pack. Firmware flash compatibility across the Mark VIe ecosystem ensures that input timing and status reporting are synchronized with controller scan rates, facilitating efficient I/O density scaling during system expansion or migration.

Frequently Asked Questions

Q: Does the IS200STCIH6A support signal loop power generation?

A: No. The STCI board serves as an interface for external field contacts. Stimulation voltage must be provided by external sources; the board provides the termination and filtering required to condition these signals for the I/O pack.

Q: Can the STCI board be mounted in different orientations?

A: Yes. The board is designed for flexibility, supporting both standard DIN-rail mounting and direct flat-surface installation within the control cabinet, depending on specific panel layout requirements.

Field Installation Guidelines

1. Mounting: Secure the board onto a standard DIN-rail or directly to the cabinet backplane using the mounting holes provided. Ensure the chassis ground point is firmly connected to the panel ground bus to ensure effective noise suppression.
2. Wiring Termination: Connect field contact wiring to the designated screw terminals. For 125 V DC inputs, maintain appropriate wire insulation ratings and physical separation from low-voltage signal cabling to prevent cross-coupling.
3. Shielding: Terminate cable shields at the cabinet ground point rather than the terminal board itself, unless specific site grounding diagrams dictate otherwise. Use ferrules on stranded conductors to ensure reliable mechanical connection within the terminal blocks.
4. Verification: After installation, perform a continuity check on all field loops. Use a digital multimeter to confirm that the stimulation voltage is correctly present at the terminal entry point before signaling the I/O pack.
