The GE IS230TCISH6C is a DIN rail-mounted I/O module used within the GE Mark VIe turbine control architecture. Available product references identify it as a TBCIS2C/YDIAS1A 125VDC TMR assembly, making the complete part number particularly important when sourcing a replacement.

The module provides an interface between field wiring and the Mark VIe control system. The Mark VIe I/O architecture uses I/O packs together with terminal boards, allowing field signals to be acquired and processed by the control system.

The IS230TCISH6C is particularly relevant to turbine and plant-control maintenance projects where an exact replacement is required for an installed GE control cabinet.

Technical Specifications

The 12-relay configuration, 4 ms hardware input filter and DIN rail mounting are among the product characteristics reported for this exact model.

Applications

The GE IS230TCISH6C can be used in:

(1) Gas turbine control systems

(2) Steam turbine control systems

(3) GE Mark VIe turbine control cabinets

(4) Plant control systems

(5) Industrial discrete signal interfaces

(6) Power generation automation

(7) Turbine maintenance and retrofit projects

Model-Specific Information

The IS230TCISH6C should be identified by the complete part number, rather than simply searching for “GE Mark VIe I/O module.”

A particularly useful identification point is its association with the TBCIS2C/YDIAS1A 125VDC TMR assembly.

The module is also described as a DIN rail I/O module with two terminal blocks, allowing field wiring to be connected directly to the assembly.

When replacing an existing unit, customers should verify:

(1) Complete part number: IS230TCISH6C

(2) Existing terminal board configuration

(3) TMR architecture

(4) Field voltage requirement

(5) Terminal block arrangement

(6) Existing Mark VIe system configuration

This is especially important for turbine control applications because an apparently similar GE I/O assembly may have a different signal type or terminal configuration.

Compatible Systems & Related Modules

The Mark VIe I/O architecture generally consists of an I/O pack mounted to a terminal board, with the terminal board providing field wiring connections and passive interface circuitry.

Replacement Information

GE IS230TCISH6C is commonly sourced for:

(1) Failed Mark VIe I/O module replacement

(2) Turbine control system maintenance

(3) TMR assembly replacement

(4) Power plant maintenance

(5) Control cabinet refurbishment

(6) Emergency spare inventory

(7) Long-term support of installed GE turbine control systems

For a direct replacement, a clear photograph of the existing module label and terminal side is recommended.

Ordering Tips

Please send:

(1) Part number

(2) Quantity

(3) Required condition

(4) Destination country

(5) Original module photo

If available, also provide the terminal-board or assembly identification printed on the existing unit.

Verification & Quality Control

Before shipment:

(1) Verify the complete model number

(2) Check product label and markings

(3) Inspect PCB and terminal blocks

(4) Inspect relays and connectors

(5) Check physical condition

(6) Perform functional testing when available

(7) Use anti-static protective packaging
