Functional Description
IS200YAICS1A is an analog I/O module developed by GE. It is a part of Mark VIeS control system. The Analog I/O Pack (YAIC) provides a seamless electrical interface between one or two I/O Ethernet networks and an analog input/output terminal board. This pack is equipped with a processor board that is standard across the Mark VIeS Safety Control distributed I/O packs, ensuring consistency and reliability. Additionally, it includes a specialized acquisition board designed specifically for handling analog input functions.
Features
- It is capable of managing up to 10 analog inputs. Of these, the first eight inputs are highly versatile, as they can be configured to accept either ±5 V or ±10 V voltage inputs, or 4-20 mA current loop inputs, depending on the specific application requirements. The final two inputs offer further flexibility, being configurable for either ±1 mA or 0-20 mA current inputs.
- For current loop inputs, the terminal board hosts the necessary load terminal resistors. Monitors the voltage across these resistors to ensure accurate readings and control. It also extends functionality by supporting two additional 0-20 mA current loop outputs, enhancing its versatility in control applications.
- Input connections are facilitated by dual RJ-45 Ethernet connectors, ensuring robust network communication, while a three-pin power input supplies the necessary power to the unit. Output is efficiently managed through a DC-37 pin connector, which directly interfaces with the corresponding terminal board connector, simplifying installation and reducing potential points of failure.
- To aid in maintenance and troubleshooting, the YAIC is equipped with visual diagnostic features, including indicator LEDs that provide real-time status updates, allowing operators to quickly assess the health and functionality of the pack.
Installation Procedure
- Mount the Terminal Board: Begin by securely mounting the terminal board in the desired location. Ensure that it is firmly fixed to avoid any movement or misalignment, which could affect the performance of the connected I/O packs.
- Plug in the I/O Packs: For a simplex configuration, directly plug one I/O pack into the terminal board connector. For a Triple Modular Redundancy (TMR) configuration, plug in three I/O packs into the respective connectors on the terminal board. Each pack must be correctly seated to ensure proper electrical connections.
- Secure the I/O Packs: Mechanically secure the I/O packs using the threaded studs located adjacent to the Ethernet ports. These studs are designed to slide into a mounting bracket that is specific to the terminal board type. Adjust the bracket location to ensure that no right-angle force is applied to the DC-37 connector between the I/O pack and the terminal board. Proper adjustment of the bracket is crucial to prevent damage to the connectors and should typically be done once during the installation process and not require further adjustment throughout the product's lifecycle.
- Connect Ethernet Cables: Depending on your system configuration, plug in one or two Ethernet cables into the appropriate ports. The pack is designed to operate through either Ethernet port. However, if dual Ethernet connections are used, it is standard practice to connect ENET1 to the network associated with the R controller, ensuring a stable and reliable communication path.
- Apply Power to the Pack: Power the I/O pack by plugging the power connector into the designated port on the side of the pack. There is no need to power down the cable before inserting the connector, as the YAIC pack includes a soft-start capability. This feature manages current inrush during power application, protecting the pack and ensuring a smooth startup process.
- Configure the I/O Pack: Once the pack is physically installed and powered on, proceed to configure the pack according to your system’s requirements. Configuration steps may include setting up input/output parameters, network settings, and other operational preferences to ensure that the pack functions correctly within your control system.
Status LEDs
The processor is equipped with several LED indicators that provide crucial information about the operation and health of the I/O pack. These LEDs, which are color-coded and clearly labeled, offer real-time feedback on various operational parameters and potential issues, helping operators to quickly assess the status of the system.
LED Indicators and Their Functions
- Yellow ENA1 and ENA2 LEDs: These yellow LEDs indicate the closure of the relays controlling outputs 1 and 2, respectively. When these LEDs are lit, it confirms that the corresponding output relay is engaged and functioning.
- Green PWR LED: This green LED displays the presence of control power, confirming that the YAIC pack is properly powered and ready for operation. Its illumination is a key indicator that the system is receiving the necessary electrical input.
- Green LINK LED: For each Ethernet port, the LINK LED indicates whether a valid Ethernet connection is established. If the LINK LED is lit, it verifies that the pack is successfully connected to the network, ensuring proper communication.
- Yellow TxRx LED: Also provided for each Ethernet port, this LED indicates when the I/O pack is actively transmitting or receiving data over the network. The TxRx LED’s activity is essential for monitoring ongoing network communication and data flow.
- Red/Green ATTN LED: This LED provides a comprehensive status overview of the I/O pack. By displaying different colors and flashing patterns, the ATTN LED signals various states of the pack, from normal operation to critical faults.
ATTN LED Flash Codes
- LED Off (Red ATTN LED not lit): This indicates that the I/O pack is operating normally, with no detectable issues.
- Solid Red ATTN LED: A solid red light signals a critical fault, which could be due to hardware failures on the processor or acquisition boards, or the absence of application code. This condition prevents the I/O pack from functioning.
- Flashing at 4 Hz (50% duty cycle): This pattern indicates an alarm condition. Alarms may include incorrect I/O pack and terminal board combinations, a missing terminal board, or errors in application code loading.
- Flashing at 1.5 Hz (50% duty cycle): This indicates that the I/O pack is not online, suggesting it is either not fully integrated into the system or currently disconnected.
- Flashing at 0.5 Hz (50% duty cycle): This specific pattern is used during factory testing and is not typically observed during normal operation.

FREQUENTLY ASKED QUESTIONS
What is IS200YAICS1A?
It is an Analog I/O Module developed by GE
How does the I/O pack monitor internal power supplies?
The I/O pack continuously monitors its internal power supplies to ensure they are operating correctly. This ongoing check is crucial for maintaining the reliability and stability of the system.
What does the I/O pack do to confirm the hardware set matches?
The I/O pack checks the electronic ID information from the terminal board, acquisition board, and processor board to confirm that the hardware set matches. It then verifies that the application code loaded from flash memory is correct for this specific hardware set.
How does the I/O pack handle analog input limit checking?
Each analog input undergoes hardware limit checking based on configurable high and low levels for 4-20 mA inputs and preset (non-configurable) levels for 5 V, 10 V, and 1 mA inputs. If an input exceeds these limits, a logic signal (L3DIAG YAIC) is set, and the input is marked as unhealthy. The system can use these limits to generate alarms and enable or disable inputs, with the option to make these limits latching or non-latching. A system reset (RESET SYS) can be used to clear out-of-limit conditions.
How does the I/O pack ensure the accuracy of the analog input hardware?
The analog input hardware includes precision reference voltages that are measured during each scan. The measured values are compared against expected values to confirm the health and accuracy of the Analog-to-Digital Converter (ADC) circuits.
