IS230PCAAH1B CORE ANALOG I/O MODULE

Fig 1: PCAA Core Analog

• Two application I/O boards, a terminal board, and a processor board that is shared by all Mark* VIe distributed I/O are all included in PCAA. The various boards that make up the module are not supported for diagnosis or replacement, making the entire module the least changeable component.

• Dual RJ45 Ethernet connectors and the 28 V dc power connector P5 are used to supply the module with input. 120 box terminals in the Euro style are located on the module edge and are used for field device I/O. Connector P4 provides power to a JGPA board. Two 68-pin cables on connectors P1 and P2 are used to connect the module to the TCAT.

• PCAA divides the signals into two categories. The TCAT terminal board is used to route signal inputs that can be fanned from a single input into a single, dual, or TMR PCAA module. The terminals of PCAA are wired with signals that are exclusive to a single PCAA module. As a result, the signal split in the following table is produced. If the fanned inputs are not necessary, PCAA can be used in place of TCAT.

Each Mark VIe I/O pack and controller is fully compatible with the PCAA module. The following table lists the frame rates, redundancy, and networking that PCAA supports.

INSTALLATION:

• Mount the PCA A 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.
