GE IS230TNAIH2C - Analog I/O DIN RAIL Module

FUNCTIONAL 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.

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.

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.
