GE IS200STAIH2ACB Compact Analog Input Terminal Board

Description

The GE IS200STAIH2ACB serves as the primary IS200STAIH2A Compact Analog Input Terminal Board utilized to execute centralized signal termination within General Electric Mark VIe control system platforms. The hardware acts as a simplex-configured physical landing interface that routes field transmitter signals directly to the associated I/O packs, supporting up to 10 analog inputs and two analog outputs via high-density terminal blocks.

I/O Density Scaling and Deterministic Networks

The board layout is engineered to maximize I/O density scaling within a compact physical footprint, matching standard terminal alignments for high-density control enclosures. The integrated circuitry works in tandem with the central processor via Profinet / EtherNet/IP deterministic networks parameters, utilizing an on-board ID chip that continuously transmits the serial number, hardware revision, and terminal position to the Programmable Analog Input Controller (PAIC) to ensure precise firmware flash compatibility and runtime hardware validation.

Frequently Asked Questions

Q: How is the second analog output channel reconfigured to support the high-current 0-200 mA range? A: The selection between the standard 0-20 mA range and the high-current 0-200 mA range is executed via a hardware jumper configuration located directly on the surface of the terminal board. This physical jumper must be set before commissioning the loop.

Q: Can this terminal board be cross-connected to support dual or TMR redundant I/O pack configurations? A: No. The IS200STAIH2ACB is designed strictly as a simplex version. It features a single set of physical DC-37 connectors on the backplane layer, which restricts its operational path to a single, non-redundant I/O pack connection.

Field Installation Guidelines

• Mount the terminal board securely into the designated enclosure slot using the integrated chassis mounting points, ensuring the surface-mount components remain free from physical contact with surrounding metal frames.
• Strip field instrumentation wires back 6 mm and insert them into the Euro-block terminal clamps. Torque all clamping screws to 0.4 Nm to ensure stable electrical connections and minimize loop contact resistance.
• Ground all field instrumentation shields at the dedicated clean earth shield bar located at the base of the terminal panel assembly to eliminate common-mode noise on the 10 analog input channels.
