Operating temperature: -30 to 65 degrees Celsius
Series: Mark VIe
IS230PCAAH1A is a Core Analog Module designed for the Mark VIe system. It is developed by
General Electric. A large portion of the analog signal I/O required to operate a gas turbine is provided
by the Core Analog (PCAA) module and associated Core Analog (TCAS and TCAT) terminal board.
Thermocouple inputs, 4-20 mA current loop I/O, seismic inputs, Linear Variable Differential Transformer
(LVDT) excitation and inputs, pulse rate inputs, and servo coil outputs are all provided by PCAA and TCAT.
Functional Description
- The module is suitable for use in simplex, dual, and TMR systems. A single TCAT terminal
- board distributes signal inputs to one, two, or three PCAA modules.
- An adjacent JGPA board’s shield ground and 24 V field power terminals supplement the terminals
- on PCAA and TCAT. Module includes a processor board that is shared by all Mark VIe distributed
- I/O boards, two application I/O boards, and a terminal board.
- The entire module is regarded as the least replaceable unit, and no assistance is provided to
- diagnose or replace the individual boards that comprise the module.
- The module is powered by a 28 V dc power connector and two RJ45 Ethernet connectors. On
- the module’s edge, 120 Euro-style box terminals provide field device I/O. Power is supplied to a
- JGPA board via connector P4. The module is connected to TCAT via two 68-pin cables on connectors P1 and P2.
- PCAA signals are divided into two groups. The TCAT terminal board routes signal inputs that can
- be fanned from a single input into a single, dual, or TMR PCAA module. Signals dedicated to a
- single PCAA module are wired to terminals. If the fanned inputs are not required, PCAA can be used without TCAT.
