GE IS230TCATH1A TCAT Core Analog Terminal Board Assembly

Core Analog Field Termination

GE IS230TCATH1A TCAT Core Analog Terminal Board Assembly

A TCAT board-and-base assembly used as the field-facing analog termination layer for PCAA-based core analog hardware.

Product Overview

GE IS230TCATH1A is identified in manufacturer system drawings as a TCAT Core Analog Module assembly. The drawings place the board at the field-termination side of a PCAA-based core analog arrangement.

Its documented signal groups include seismic inputs, LVDT winding inputs, 4–20 mA transmitter inputs and magnetic pulse-rate inputs. The assembly can route its signals to one or three PCAA modules, depending on the configured redundancy arrangement.

The complete IS230TCATH1A order number is important because the board, base, terminal arrangement and paired PCAA connections form one installation assembly.

Analog Signal Termination

Multiple sensor classes on one terminal assembly

The TCAT arrangement terminates four analog signal classes. Jumper positions beside the 4–20 mA terminals determine whether the return is grounded or left floating, with the documented default shown open.

Twenty-four 4–20 mA transmitter inputs.
Twelve seismic and twelve LVDT winding inputs.
Two magnetic pulse-rate inputs.

PCAA Integration and Diagnostics

Paired cables and electronic identification

TCAT connections to PCAA are used in pairs. The electronic identification associated with each cable connection allows the PCAA hardware to verify that the correct TCAT cable is installed. TCAT diagnostics are recorded through the connected PCAA module.

Use paired 68-pin connections.
Select simplex or redundant arrangements from the project documentation.
Keep JGPA transmitter-supply terminals adjacent to the TCAT field terminals.

Technical Questions

What is included in the IS230TCATH1A identity?

It identifies the GE TCAT core analog terminal board assembly and base arrangement.

How many 4–20 mA inputs are documented for IS230TCATH1A?

The TCAT assembly provides 24 4–20 mA inputs.

Which additional input groups are terminated by IS230TCATH1A?

The documented groups include 12 seismic inputs, 12 LVDT winding inputs and two magnetic pulse-rate inputs.

How does IS230TCATH1A connect to PCAA modules?

It uses paired 68-pin connections and can serve one or three PCAA modules according to the configured redundancy.

Why should the complete IS230TCATH1A assembly number be checked?

The order number identifies the terminal board, base and connection arrangement that must match the installed core analog hardware.
