GE Mark VIe IS220PDIOH1A Discrete Inputs/Outputs

FUNCTIONAL DESCRIPTION:

IS220PDIAH1A is a Discrete Contact Input Terminal Board manufactured and designed by General Electric as part of

the Mark VIe Series used in GE Distributed Turbine Control Systems. 

The PDIA I/O pack provides the electrical interface between one or two I/O Ethernet networks and a discrete input terminal board. 

The pack contains a processor board common to all Mark VIe distributed I/O packs and an acquisition board specific to the discrete input function.

The pack accepts up to 24 contact inputs and terminal board-specific feedback signals, 

and PDIA accepts three different voltage levels (with types TBCIH1. H2. and H3 terminal boards). 

Connections for the isolated discrete input board with voltage sensing (with type TICI board) are available. 

System input to the pack is through dual RJ45 Ethernet connectors and a three-pin power input. 

Discrete signal input is through a DC-37 pin connector that connects directly with the associated terminal board connector.

Visual diagnostics are provided through indicator LEDs, and local diagnostic serial communications are possible through an infrared port.

INSTALLATION:

Securely mount the desired terminal board.

Directly plug one PDIA I/O pack for simplex or three PDIA I/O packs for TMR into the terminal board connectors.

Mechanically secure the packs using the threaded studs adjacent to the Ethernet ports. 

The studs slide into a mounting bracket specific to the terminal board type.

The bracket location should be adjusted such that there is no right-angle force applied to the DC37 connector between the pack and the terminal board.

The adjustment should only be required once in the life of the product.

Plug in one or two Ethernet cables depending on the system configuration.

The pack will operate over either port. If dual connections are used, the standard practice is to connect ENET1 to the network associated with the R controller.

Apply power to the pack by plugging in the connector on the side of the pack.

It is not necessary to insert this connector with the power removed from the cable as the I/O pack has inherent soft-start capability that controls the current inrush on the power application.

COMPATIBILITY:

PDIAH1A is compatible with five types of discrete contact input terminal boards, including the TBCI boards, TICI boards, 

and STCI boards, but not the DIN-rail mounted DTCI board. Control mode refers to the number of I/O packs used in a signal path:

One I/O pack and one or two network connections are used in Simplex.

Dual uses two I/O packs with one or two network connections.

Three I/O packs with one network connection each are used by TMR.
