IS400TCASH1A GE Core Analog (PCAA) Module Terminal Board

Description:

IS230PCAAH1B is a Core Analog I/O Module manufactured and designed by General Electric as part of the Mark VIe Series used in distributed control systems. A sizable amount of the analog signal I/O needed to run a gas turbine is provided by the Core Analog (PCAA) module and related Core Analog (TCAS and TCAT) terminal board. Thermocouple, 4-20 mA current loop, seismic, linear variable differential transformer (LVDT) excitation and inputs, pulse rate, and servo coil outputs are all provided by PCAA and TCAT. In simplex, dual, and TMR systems, PCAA is applicable. To one, two, or three linked PCAA modules, a single TCAT terminal board fans signal inputs. In addition to the terminals on PCAA and TCAT, a nearby JGPA board also has shield ground and 24 V field power connectors.

INSTALLATION:

Mount the PCAA module firmly.
Attach the P4 connector on the PCAA to the JGPA power connection.
Attach two 68-pin cables to connectors P1 and P2 on a TCAT terminal board that is optionally coupled with the PCAA module. A network connection pairs the connectors on TCAT. PS1 and PS2 connect to a PCAA that is part of the S controller network, PT1, and PT2 connect to a PCAA that is part of the T controller network, and PR1 and PR2 connect to a PCAA that is part of the R controller network.
To maintain adequate cable grounding, it is crucial to just finger-tighten the mounting screws into PCAA and TCAT. If the wires are not secured, PCAA may be unable to read the electronic ID on TCAT, which could degrade other communications.
Depending on the setup of the machine, connect either one or two Ethernet wires. The module works properly over either port when a single IONet connection is utilized. The R controller's network should be connected to ENET1 if dual connections are being used.
The PCAA, however, does not care how an Ethernet connection is made and negotiates correct functionality via either port. The network connection should match the connection made to TCAT if TMR PCAA modules are present. For instance, cables to the TCAT PR1 and PR2 connectors should be present on the PCAA module with the R IONet connection.
Verify that the JGPA shield wire terminals are grounded. The JGPA shield ground connections are typically electrically connected to the sheet metal that the board is mounted on. The ground path for the terminals is then provided by the mounting.
It may be necessary for some situations to specify a shield ground that is separate from the mounting sheet metal. The JGPA is mounted in these applications utilizing hardware that separates the board from the sheet metal. Between one or more JGPA terminals and the necessary shield ground potential in these applications, a suitable ground wire must be provided.
Check the power and Ethernet status indicator lights after powering on the module using the P5 connector.
