GE IS220PDIIH1A Discrete Contact Input Terminal Board

GE IS220PDIIH1A Discrete Contact Input Terminal Board

Part Number IS220PDIIH1A Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VIe Function Module Availability In StockIS220PDIIH1A is an I/O Pack under the Mark VIe series. The component is developed by GE under Speedtronic. Depending on the terminal and possible board configurations, the pack can receive up to 16 isolated contact inputs that can be point isolated, group isolated, or a mix. Different voltage levels can be accepted by each channel. 

 The electrical link between one or two I/O Ethernet networks and a point/group isolated discrete input terminal board is provided by the Isolated Discrete Input (PDII) pack. The pack includes a processor board that is shared by all Mark VIe distributed I/O packs as well as an acquisition board that is dedicated to the isolated discrete input function. All 16 channels can be system wetted with 24 V dc, 115 V ac RMS, or 230 V ac RMS if the pack is utilized with terminal board SDII and optional board WDIIH1. When using WDIIH1, each of the 16 channels can be set as point isolated and accept a varied voltage level as desired. This configuration allows for a combination of point and group isolation.

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.

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.

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.

OPERATIONS:

High-speed processor with RAM and flash memory

Two fully independent 10/100 Ethernet ports with connectors

Hardware watchdog timer and reset circuit

Local ambient temperature sensor

Infrared serial communications port

Status-indication LEDs

Electronic ID and the ability to read IDs on other boards

Substantial programmable logic supporting the acquisition board

Input power connector with soft start/current limiter

Local power supplies, including sequencing and monitoring
