GE Mark VIe IS220PDOAH1A Discrete Output I/O pack

Overview of IS220PDOAH1A

The IS220PDOAH1A is a Discrete Output Pack designed for seamless integration with two I/O Ethernet networks and other discrete output terminal boards. One of its standout features is the ability to control up to twelve relays. Additionally, it can receive feedback signals from external terminal boards. This pack is compatible with both solid-state and electromagnetic relays, providing flexibility in its usage.

Relay Compatibility and Terminal Boards

For solid-state relays, you can use terminals TRLYH1B, C, D, and F. Meanwhile, electromagnetic relays are supported by the TRLYH1E terminal boards. These connections ensure a wide range of relay options to meet different needs.

Input and Power Connections

The IS220PDOAH1A pack accepts inputs through two RJ45 Ethernet connectors and a three-pin power input. This setup enables efficient communication and power delivery for optimal performance.

Processor and Functionality

The IS220PDOAH1A contains an embedded processor board with various components. These include status-indicating LEDs, local power supplies, and a high-speed processor. The processor features both flash and RAM memory for reliable performance. Detailed information about these processors can be found in the GEH-721G Mark VIe Control System Guide (pages 223 to 230).

Output Enable Function

The IS220PDOAH1A features an output enable function that plays a crucial role during power-up. Initially, all outputs remain disabled until several internal self-tests are completed. The enable function ensures that the relays stay dropped out, even during initialization, which helps maintain system stability.
