IS220YDOAS1A - Discrete Output Pack

Functional Description

IS220YDOAS1A is a discrete output pack developed by GE. It is a part of Mark VIeS control system. The I/O pack serves as a crucial electrical interface, facilitating seamless connectivity between one or two I/O Ethernet networks and a discrete output terminal board. Its design encompasses a common processor board along with an acquisition board explicitly tailored to the discrete output function, ensuring efficient and precise operation.

Input and Output Interfaces

• The I/O pack efficiently interfaces with external components through a dual RJ-45 Ethernet connector setup, bolstered by a three-pin power input mechanism.
• Output functionality is facilitated via a DC-37 pin connector, establishing a direct and reliable connection with the associated terminal board connector. This streamlined interface architecture ensures seamless transmission and reception of signals.

Diagnostic Features

• Incorporated within the I/O pack are indicator LEDs that serve as visual diagnostic aids. These LEDs play a pivotal role in providing real-time status updates and alerts, enhancing the overall monitoring and troubleshooting capabilities of the system. Their presence significantly contributes to the ease of identifying and resolving potential issues promptly.
• It stands as an indispensable component, offering a robust electrical bridge between Ethernet networks and discrete output terminal boards. With its versatile relay control, diverse compatibility with terminal boards, and intuitive diagnostic features, it serves as a reliable and adaptable solution for various industrial and technological applications.

Compatibility

• Primarily, the pack exhibits remarkable capability, enabling control over a maximum of 12 relays.
• Its operational scope extends to accepting terminal board-specific feedback, providing a comprehensive and versatile solution for diverse application needs. Notably, it accommodates various electromagnetic relay types, such as TRLYS1B, D, and F terminal boards, thereby enhancing adaptability.

Installation

• Terminal Board Mounting: Securely mount the preferred terminal board onto the designated space.
• YDOA Connection: For simplex operation, directly plug in one YDOA. For TMR, connect three YDOAs into the terminal board connectors.
• Pack Securing Process: Mechanically secure the packs utilizing the threaded studs located adjacent to the Ethernet ports. These studs fit into a mounting bracket specific to the terminal board type. Adjust the bracket's positioning to ensure there is no right-angle force exerted on the DC-37 connector linking the pack and terminal board. This adjustment is typically a one-time requirement throughout the product's lifespan.
• Ethernet Cable Connection: Plug in one or two Ethernet cables based on the system configuration. The I/O pack functions seamlessly over either port. When using dual connections, it's recommended to link ENET1 to the network associated with the R controller.
• Power Application: Apply power to the pack by inserting the connector on the side of the I/O pack. The pack's inherent soft-start capability regulates current inrush during power application, eliminating the need to remove power from the cable before inserting the connector.
• Configuration with ToolboxST Application: Utilize the ToolboxST application to configure the YDOA according to specific operational requirements.
