The GE IS230TAISH2C, also cataloged as the IS230TAIS Simplex Analog Input Terminal Board, operates as a dedicated hardware component for analog signal termination and distribution within GE Mark VIe control networks. Mounted on a DIN rail assembly, the board accepts 4-20 mA current loops, 0-10 VDC inputs, and 2-wire or 4-wire transmitter connections, interfacing field sensors directly to I/O pack modules.

Deterministic Backplane Bus Velocity and I/O Density Scaling
The IS230TAISH2C provides high signal fidelity to preserve backplane bus communication velocity across the Mark VIe IONet architecture. Designed for compact panel layouts, the board optimizes I/O density scaling by routing multiple analog input channels through a single high-density connector interface. Integrated onboard passive filter networks ensure signal stabilization and firmware flash compatibility across attached I/O packs, preventing line noise from interfering with real-time analog-to-digital conversions.
Frequently Asked Questions
Q: How is the IS230TAISH2C physically secured in the control enclosure?
A: The board mounts directly onto standard 35 mm DIN rails via integrated locking clips, providing mechanical stability and earthing contact.
Q: Does the IS230TAISH2C contain active processing components or microprocessors?
A: No, the IS230TAISH2C functions as a passive field termination board that interfaces directly with an active Mark VIe I/O pack module for signal processing.
Q: How are field wiring shields managed on this termination assembly?
A: Shield wires terminate at designated ground terminals on the board assembly, which route high-frequency noise directly to the grounded DIN rail chassis.
Field Installation Guidelines
- Disconnect all external loop power sources before connecting or disconnecting field wiring on the IS230TAISH2C assembly.
- Snap the board securely onto a clean, grounded 35 mm DIN rail, verifying that the retaining clips engage completely.
- Wear an ESD grounding wrist strap attached to an unpainted enclosure ground point during installation.
- Route field analog input cables in dedicated low-voltage wiring troughs, separated from high-voltage AC power lines.
- Tighten all field screw terminals to 0.5 Nm (4.4 in-lbs) and confirm D-sub cable connectors are fully screwed down to the I/O pack interface.
