About the GE IS220PDOAH1A PROPORTIONAL DIGITAL OUTPUT MODULE

FUNCTIONAL DESCRIPTION:

IS220PDOAH1A is a Proportional Digital Output Module Manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Gas Turbine Control Systems. The PDOA provides the electrical interface between one or two I/O Ethernet networks and a discrete output 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 output function. The pack can control up to 12 relays and accepts terminal board-specific feedback. Electromagnetic relays (with types TRLYH1B, C, D, and F terminal boards) and solid-state relays (with type TRLYH1E boards) are available. Input to the pack is through dual RJ45 Ethernet connectors and a three-pin power input. Output is through a DC-37 pin connector 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:

PDOAH1A is compatible with six types of discrete (relay) output terminal boards, including the TRLY boards and SRLY boards, but not the DIN-rail mounted DRLY boards. The following table gives details of the compatibility:

Simplex uses one I/O pack with one or two network connections.
Dual uses two I/O packs with one or two network connections.
TMR uses three I/O packs with one network connection on each.

INSTALLATION:

Directly plug one PDOA I/O pack for simplex or three PDOA 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.

Frequently Asked Questions about IS220PDOAH1A 

Q:What is the role of the soft-start circuit in the IS220PDOAH1A 
 module?
A:The soft-start circuit gradually ramps up the voltage applied to the processor board, reducing inrush current and preventing potential damage during power-up.

Q:What kind of Ethernet connectivity does the IS220PDOAH1A offer?
A:The module features two 10BaseT/100BaseTX Ethernet ports with RJ-45 connectors.

Q:How does the IS220PDOAH1A module ensure compatibility with terminal boards?
A:The module performs a self-test and checks board ID information to confirm compatibility with the terminal board and application code before establishing Ethernet communications and beginning operation.
