GE IS220YDOAS1AJ Turbine Control Board

Description

GE IS220YDOAS1AJ Mark VIeS Discrete Output Pack
Description:
The Discrete Output (YDOA) 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 TRLYSlB, D, and F terminalboards) are available. Input to the pack is through dual RJ-45 Ethernet connectors and athree-pin power input. Output is through a DC-37 pin connector that connects directly with the associated terminal board connector. Visual diagnostics are provided throughindicator LEDs.
Number of Relay Channels: 12 relays (different types depending on the terminal board)
Relay and Coil Monitoring: 12 relay/coil monitors, 3—fuse status feedbacks are multiplexed to read status from Relay and Coil Monitoring bef six fuses
I/O Pack Response Time: From Ethernet command to output is approximately 6 ms
SOE Reporting: Each relay can be configured to report operation in the Sequence of Events (SOE)record
Size: 8.26 cm high x 4.19 cm wide x 12.1 cm deep
Technology: Surface-mount
Ambient Rating for Enclosure Designt: -30 to 65°C (-22 to 149 °F)
The lO pack performs the following self-diagnostie tests:

• A power-up self-test that includes checks of’ RAM, flash memory, Ethernet ports, and processor board hardwareContinuous monitoring ofthe internal power supplies for correct operation
• A check of the electronic ll) information from the terminal board, acquisition board, and processor board to confirm thatthe hardware set matches, followed by a check that the application code loaded from flash memory is correct for thehardware set.
• A comparison is made between the commanded state of each relay drive and the feedback from the command outputcircuit.
• Relay board specific feedback is read by the pack and processed. T’he information varies depending on the relay boardtype. Refer to relay terminal board documentation for feedback specifics.
