(2)Role

The IS230PCAAH1A is a basic analog module designed for the Mark VIe system. It was developed by General Electric. The core analog module (PCAA) and the associated core analog terminal boards (TCAS and TCAT) provide most of the analog I/O signals required to operate a gas turbine. The PCAA and TCAT provide thermocouple inputs, 4-20mA current loop I/O, seismic inputs, excitation and linear variable differential transformer (LVDT), pulse frequency inputs, and servo coil outputs.

(4) IS230PCAAH1A Installation

Securely secure the PCAA module.
Connect the JGPA power supply to the P4 connector of the PCAA.
Connect the PCAA module to the optional associated TCAT terminal block using two 68-pin cables on connectors P1 and P2. Network connections connect the TCAT connectors. PR1 and PR2 connect to the R controller network, PS1 and PS2 connect to the S controller network, and PT1 and PT2 connect to the T controller network. To ensure proper grounding of the cables, fully install the cable mounting screws (hand tight only) into the PCAA and TCAT. Failure to secure the cables may prevent the module from reading the electronic ID on the TCAT and may degrade other signals.
Depending on the system configuration, connect one or two Ethernet cables. When only one IONet connection is used, the module can be used on either port. When using dual connections, ENET1 is typically connected to the network associated with the R controller. PCAA, on the other hand, is indifferent to Ethernet connections and will negotiate proper operation on either port. If a TMR module is present, the network connection should correspond to the TCAT connection. For example, a PCAA module with R IONet connections should have cables connected to the TCAT PR1 and PR2 connectors.
Verify that the JGPA shield wire terminals are properly grounded. In most cases, the JGPA shield ground terminal is electrically connected to the metal plate to which the circuit board is mounted. Then install the ground path used as the terminal. In some applications, it is necessary to define a shield ground independent of the mounting metal plate. In these applications, the JGPA is mounted using hardware that isolates the circuit board from the metal plate. In these applications, it is critical to provide a suitable ground wire between one or more JGPA terminals and the desired shield ground potential.
Connect the module to power through the P5 connector and check the power and Ethernet status indicators.
If necessary, configure the I/O package using the ToolboxST application.

(5)Processor Features

Two fully independent 10/100 Ethernet ports with connectors
Hardware watchdog timer and reset circuitry
Internal temperature sensor
Status indicator LEDs
Electronic ID and ability to read IDs from other boards
Soft start/current limiter on input power connector
Local power supply, including sequencing and monitoring
Power Management
The 28 V input circuit includes power management. Management provides soft start to control current surges during power up.
After power up, the circuit implements fast current limiting to prevent power disturbances in the module from propagating back into the 28 V power system.
The green PWR indicator will illuminate

(6)Power Management

The 28 V input circuit includes power management. The management function provides soft start to control the current surge during power up.
After power up, the circuit implements a fast current limit function to prevent power disturbances in the module from propagating back into the 28 V power system.
The green PWR indicator will illuminate when power is present and operating normally. If the current limit function is enabled, the indicator will remain on until the problem is resolved.
