Description
🔹 Product Description
The GE General Electric IS230TCISH9, associated with IS230TCISH9C, is a TCIS I/O Terminal Board assembly for the GE Mark VI Speedtronic turbine control platform. Technical references identify it as a Group 9 IS230 special assembly with conformal PCB coating and DIN-rail mounting capability.
The assembly is designed for discrete contact input interfacing. References identify two long terminal blocks, 24 contact points per block, 24 metal-oxide varistors, and two IS220YDIAS1A plug-in I/O modules on the IS230TCISH9 version. The IS230TCISH9C variant is documented with three vertical 37-pin connectors and a DIN-rail mounting frame.

The IS230TCISH9C is documented as a Mark VI I/O terminal board with 24 contact inputs and 125 VDC nominal input power, while the IS230TCISH9 version is described with two IS220YDIAS1A modules. Because the two designations represent different assembly/revision configurations, the exact board suffix should be matched before replacement.
🔹 Common Questions & Answers
Q: What is the GE IS230TCISH9?
A: It is a GE TCIS I/O Terminal Board assembly used for discrete contact input interfacing in compatible Mark VI/Mark VIe turbine-control systems.
Q: What is the difference between IS230TCISH9 and IS230TCISH9C?
A: IS230TCISH9 is the base assembly designation, while IS230TCISH9C is a documented C-revision functional board designation. Their connector and hardware configurations should be checked against the existing installation before replacement.
Q: How many contact inputs does the IS230TCISH9C support?
A: Technical references identify 24 contact inputs.
Q: What I/O modules are associated with the IS230TCISH9?
A: The IS230TCISH9 version is documented with two IS220YDIAS1A modules attached to the terminal board.
Q: Can the board be DIN-rail mounted?
A: Yes. The IS230TCISH9C uses a metal mounting frame that allows DIN-rail installation; flat/base mounting is also supported depending on the assembly configuration.
Q: What is the nominal input voltage?
A: The IS230TCISH9C is documented with 125 VDC nominal input power. Verify the actual system wiring and application documentation before energizing the board.
Q: Is the PCB conformally coated?
A: Yes. The IS230TCISH9C is documented with conformal PCB coating.
Q: What condition is this listing?
A: The supplied listing identifies the item as “NO BOX.” The physical condition should be verified from the actual unit and listing photos before purchase.
Q: Can IS230TCISH9C directly replace another TCIS board?
A: Do not assume direct interchangeability. Check the complete part number, revision, terminal arrangement, I/O pack configuration, wiring, and Mark VI system configuration.
Q: What should be checked before installation?
A: Confirm the full part number, inspect terminal blocks and connectors, verify the I/O pack configuration, check field wiring and input voltage, and follow the applicable GE Mark VI installation and maintenance procedures.
