Configured for multi‑range analog acquisition and servo‑coil actuation in Mark VIe control networks, the GE IS230PCAAH1B (IS230PCAAH1B core analog module) provides 25 analog inputs, 4‑20 mA outputs, LVDT excitation monitoring, pulse‑rate inputs, and servo‑driver channels. It interfaces directly with TCAS/TCAT terminal boards and supports simplex, dual, and TMR architectures.

Profinet / EtherNet/IP Deterministic Networks
Within Mark VIe architectures, the PCAA module aligns with deterministic IONet timing required for synchronous analog‑signal acquisition. Its fixed routing paths maintain stable propagation intervals for thermocouple, seismic, LVDT, and servo‑coil channels. I/O density scaling is achieved through TCAT fan‑out to one, two, or three linked PCAA modules. Firmware flash compatibility resides entirely at the controller level; PCAA hardware characteristics remain fixed across all variants.
Frequently Asked Questions
Q: Can the IS230PCAAH1B be replaced while energized? A: No. The module must be removed only when the associated Mark VIe segment is de‑energized to avoid transient loading on analog‑excitation and servo‑driver rails.
Q: Does the module impose restrictions on LVDT wiring? A: Yes. LVDT excitation and return wiring must follow TCAT terminal‑board pin assignments to maintain ±1.00% monitor accuracy.
Q: How does the module behave in TMR configurations? A: PCAA provides fixed electrical routing; redundancy timing and voting behavior are governed by controller logic rather than by any internal switching mechanism on the module.
Field Installation Guidelines
Maintain separation between thermocouple wiring and servo‑coil conductors to reduce noise coupling.
Bond shielded cables at a single termination point to avoid ground‑loop formation.
Verify correct polarity for 28 V dc supply before energizing the rack.
Ensure TCAT/TCAS connectors are fully seated to maintain deterministic analog‑signal routing.
Inspect field‑power and shield‑ground connections on the adjacent JGPA board.
