FUNCTIONAL DESCRIPTION:

IS220YDOAS1B is a Discrete Output Module Manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Turbine Control Systems. The Discrete Output (IS420YDOAS1B) pack provides the electrical interface between one or two I/O Ethernet networks and a discrete output terminal board. The pack contains a common processor board and an acquisition board specific to the discrete output function. The YDOA is capable of controlling up to 12 relays and accepts terminal board-specific feedback. Electromagnetic relays (with types TRLYS1B, D, and F terminal boards) are available. Input to the pack is through dual RJ-45 Ethernet connectors and a three-pin power input. Output is through a DC-37 pin connector that connects directly with the associated terminal board connector. Visual diagnostics are provided through indicator LEDs.

YDOA INSTALLATION:

  • Securely mount the desired terminal board.
  • Directly plug one YDOA for simplex or three YDOAs 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 DC-37 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 I/O 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 I/O pack. It is not necessary to insert this connector with the power removed from the cable as the YDOA has inherent soft-start capability that controls the current inrush on the power application.
  • Use the ToolboxST application to configure the YDOA as necessary.

OPERATION:

The YDOA relay command signals are the first stage of signal conditioning and level shifting to interface the terminal board outputs to the control logic. Each output is an open collector transistor circuit with a current monitor to sense when the output is picked up and connected to a load. The status LEDs and monitor outputs indicate when an output is picked up and connected to the terminal board. If output is picked up and the correct load is not sensed, the status LED will be off and the monitor line will be false. All of the outputs are disabled during power application until a variety of internal self-tests are completed. An enable line reflects the status of all required conditions for operation. This function provides a path independent of the command to ensure relays stay dropped out during power-up and initialization.

FREQUENTLY ASKED QUESTIONS:

How many output channels do discrete output modules usually have?

The number of output channels varies depending on the specific module. They can range from a few channels to dozens or even hundreds, depending on the application requirements.

Can discrete output modules handle high-current loads?

Some discrete output modules are designed to handle higher current loads directly, while others may require additional relays or power amplifiers to control such loads safely.

What are the considerations for selecting a discrete output module?

When selecting a discrete output module, factors such as the number of output channels, voltage and current ratings, response time, compatibility with the control system, and environmental conditions (such as temperature and humidity) should be taken into account.
