General Electric IS200STAIH2A Mark VIe Simplex Analog Input Terminal Board

Hardware Specifications

I/O Density Scaling and Firmware Flash Compatibility

The hardware architecture of the IS200STAIH2A supports scalable I/O processing across ten distinct analog inputs and two jumper-configurable analog outputs. Featuring high-density Euro-block terminal connections, the board interfaces directly with the Mark VIe controller pack to process two-wire, three-wire, four-wire, and externally powered transmitters. The onboard ID chip communicates terminal board parameters, revision levels, and electronic keying data to the backplane network automatically upon initialization. Furthermore, firmware flash compatibility ensures that runtime parameters, calibration profiles, and input filtering characteristics synchronize seamlessly with system configuration tools during runtime updates.

Frequently Asked Questions

Q: What is the maximum lead resistance tolerance for the analog inputs?

A: The input channels tolerate a maximum lead resistance of 15 Ohm before signal attenuation affects measurement accuracy.

Q: Are the analog outputs jumper-configurable?

A: Yes, the two 0-20 mA analog outputs are jumper-configurable, with one channel specifically rated to support up to a 200 mA current loop.

Q: How does the terminal board identify itself to the control system?

A: An onboard ID chip stores board identification data, enabling the Mark VIe pack to execute system diagnostics and electronic keying verification upon startup.

Field Installation Guidelines

• Verify that all power sources to the Mark VIe rack are completely isolated before mounting or dismounting the IS200STAIH2A terminal board.
• Secure the hardware securely onto the designated pack mount using appropriate mechanical fasteners to ensure reliable ground continuity.
• Terminate incoming signal cables strictly into the high-density Euro-block terminals, maintaining proper shielding practices to mitigate electromagnetic interference in industrial environments.
• Inspect jumper settings for the dual analog outputs prior to energization to ensure correct current scaling configuration matches field requirements.
