More Information

Overview Manuals Signal Distribution Redundancy Setup Cabling Commissioning

Features:

  • Field wiring can be landed once and routed to the required PCAA processing channels.
  • The same TCAT concept supports one, two, or three connected core analog modules.
  • The catalog covers the TCAT card and base, so service work should not treat it as an unidentified loose board.
The terminal assembly sits between project field wiring and the PCAA modules that perform conversion, processing, communication, and control functions.

Correct operation depends on the installed cable set, channel fanout, jumpers, grounding, and the relationship between shared and module-dedicated signals.

A controlled replacement preserves the original drawing references and verifies every participating processing channel before the system returns to automatic operation.

All prices are shown in USD.

How the TCAT assembly distributes signals

  • Shared inputs: TCAT-routed points can be presented to multiple PCAA modules for redundant processing.
  • Dedicated points: Signals wired directly to an individual PCAA remain outside the common fanout path and must be recorded separately.
  • Channel identity: Terminal numbers, signal names, polarity, and engineering ranges should match the project drawings and controller database.
  • Shield continuity: Cable shields and adjacent grounding provisions must follow the cabinet design to limit analog noise.
  • Loop-power boundary: Confirm which external or JGPA supply energizes each transmitter before changing terminations.

Simplex, dual, and TMR signal fanout

  • Simplex arrangement: One PCAA receives the required shared signals when no redundant processing path is specified.
  • Dual arrangement: Two module connections must use the assigned cable paths and matching configuration.
  • TMR arrangement: Three PCAA channels should show consistent wiring, point ownership, and diagnostic health.
  • Fanout review: Verify that only the intended signals are distributed across redundant modules.
  • Maintenance boundary: Isolate the affected processing channel without disturbing healthy paths whenever the approved procedure permits.

Cabling and grounding

  • Interconnect pairs: Route both 68-pin cables for each PCAA according to the cabinet drawing and connector designation.
  • Strain relief: Support the cable bundle so connector weight does not load the terminal-board headers.
  • Separation: Keep low-level analog wiring away from high-current switching conductors and noisy power circuits.
  • Shield landing: Terminate shields at the specified JGPA or cabinet grounding point without creating unintended loops.
  • Connector inspection: Check latches, keying, bent contacts, contamination, and seating before power is applied.

Commissioning checks

  • Drawing reconciliation: Compare actual terminals, jumpers, cables, and PCAA assignments with the latest approved wiring package.
  • Point-to-point test: Inject representative signals and confirm they reach every intended processing channel with correct polarity.
  • Redundancy comparison: Review channel-to-channel differences before enabling alarms, logic, or closed-loop control.
  • Loop-power test: Measure field supply and transmitter current under operating load rather than assuming the auxiliary board is included.
  • Final inspection: Record connector torque, shield continuity, diagnostic status, and restored cabinet barriers.
Description
Field analog connections reach compatible PCAA modules through the General Electric IS230TCATH1A Mark VIe TCAT Core Analog Assembly. It provides the physical board, base, and cable interfaces needed to organize the analog signal path inside the cabinet.

One, two, or three PCAA modules can be used with IS230TCATH1A according to simplex, dual, or TMR architecture. Each module connects through the matched 68-pin cable pair, allowing the assembly to route the required signals without changing the field-termination strategy for every redundancy level.

The IS230TCATH1A assembly also participates in cabinet grounding and auxiliary-power distribution through the compatible grounding and power hardware. Cable placement, connector identity, and base orientation therefore matter as much as the board part number when an installed unit is identified or replaced.

Before energizing IS230TCATH1A, compare the cabinet drawings with the fitted PCAA count, cable destinations, grounding connection, and 24 V dc power route. A point-to-point inspection prevents a swapped cable or incomplete base connection from being mistaken for an analog-processing failure.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Is General Electric IS230TCATH1A the same item as a PCAA module?
No. General Electric IS230TCATH1A is the TCAT card-and-base assembly that distributes selected signals; the PCAA is the associated processor and analog I/O module.
Does every simplex PCAA installation require General Electric IS230TCATH1A?
Not necessarily. General Electric IS230TCATH1A is used where the project needs TCAT signal fanout; a simplex PCAA arrangement may omit it when those shared inputs are not required.
What should be recorded before ordering General Electric IS230TCATH1A?
Copy the complete General Electric IS230TCATH1A catalog, installed base details, PCAA catalogs, redundancy mode, cable part numbers, and project termination drawing.
Why might one PCAA channel stop receiving signals from General Electric IS230TCATH1A?
Inspect the two multi-pin cables, connector seating, channel assignment, and the affected PCAA diagnostics; General Electric IS230TCATH1A fanout should then be compared across healthy channels.
Can General Electric IS230TCATH1A be exchanged without rechecking field loops?
No. After replacing General Electric IS230TCATH1A, verify cable routing, jumpers, terminal tightness, signal polarity, and each shared input at all participating PCAA modules.
What is the purpose of JGPA hardware beside General Electric IS230TCATH1A?
Where specified, JGPA provides shield termination and 24 V field-loop power adjacent to General Electric IS230TCATH1A; it should not be assumed to be included with the TCAT assembly.
How should a redundancy mismatch around General Electric IS230TCATH1A be investigated?
Compare the configured simplex, dual, or TMR arrangement with actual General Electric IS230TCATH1A cabling and confirm that each PCAA is assigned to the intended processing channel.
