Product Attributes
- Connection and Compatibility: Seamless integration with the VSVO processor board is facilitated through a standardized 37-pin cable interface, ensuring compatibility with existing system configurations. This cable interface aligns with those utilized on larger TSVO boards, streamlining installation and maintenance procedures.
- Versatile Mounting Options: The board's compact design allows for efficient utilization of space, with the flexibility to stack terminal boards vertically on DIN-rails. This space-saving configuration optimizes cabinet space usage, ensuring efficient layout and organization within industrial control systems.
- Scalability and Configuration Options: For applications requiring expanded functionality, it supports the connection of multiple boards to the VSVO processor board, accommodating diverse system requirements. However, it's important to note that only the simplex version is currently available, providing streamlined functionality tailored to specific application needs.
- With its compact design, comprehensive features, and seamless compatibility with VSVO processor boards, it offers unparalleled performance and flexibility in industrial automation environments. Whether used for precise motion control or flow measurement tasks, the board stands as a trusted component for enhancing operational efficiency and system reliability.
Installation
- Mounting the Holder: The board is first inserted into a plastic holder specifically designed for DIN-rail mounting. This holder securely mounts onto the DIN-rail, providing stability and ease of access for installation and maintenance tasks.
- Wiring Servo I/O: The servo input/output (I/O) connections are wired directly to the Euro-Block type terminal block affixed to the board. Depending on the specific model variant, the terminal block may feature either 36 terminals (DSVOH1A) or 42 terminals (DSVOH1B, H2B). Typically, #18 AWG shielded twisted pair wiring is used for these connections, ensuring reliable signal transmission and minimizing electromagnetic interference.
- Ground Connection: Grounding is crucial for maintaining signal integrity and electrical safety within the system. The board features six screws dedicated to the SCOM (ground) connection. It's essential to ensure that these ground connections are made with the shortest distance possible to minimize the risk of interference and optimize system performance.
Fault Detection
- Servo Current Out of Limits or Not Responding:
- Check servo motor connections and ensure they are securely connected to the board.
- Verify servo coil current settings using jumper configurations and ensure they align with the motor specifications.
- Monitor servo output signals and compare them with expected values to identify abnormalities.
- Inspect the servo motor for mechanical issues or binding that may impede its movement.
- Conduct a functional test to validate servo motor operation under load conditions.
- Excitation Out of Range:
- Verify power supply connections to the board and ensure adequate voltage levels are maintained.
- Check wiring connections to the sensors and ensure they are securely terminated.
- Measure excitation voltage levels at the terminals and compare them with specified values.
- Inspect sensor cables for damage or wear that may affect signal integrity.
- Calibrate sensors as per manufacturer recommendations to ensure accurate position feedback.
- LVDT Feedback Out of Limits:
- Monitor feedback signals and compare them with expected position values.
- Verify wiring connections and ensure proper termination to the board.
- Check for mechanical obstructions or misalignments affecting sensor performance.
- Inspect signal conditioning circuits and ensure they are functioning correctly.
- Recalibrate sensors and adjust signal processing parameters as needed.
- Failed ID Chip:
- Verify ID chip connections and ensure they are securely seated on the board.
- Check for physical damage or corrosion on the ID chip and surrounding components.
- Replace the ID chip with a compatible spare to determine if the fault persists.
- Inspect communication interfaces and connectors for damage or contamination.
- Reset the board and restart the system to re-establish communication.

Frequently Asked Questions
What is IS210DSVOH1B?
It is a Servo Terminal Board developed by GE under the Mark VI series.
What happens if the output servo current is out of limits or not responding?
In such cases, a fault is generated within the system, indicating potential issues with servo motor operation or control loop integrity.
What happens if the LVDT feedback signal is out of limits?
If the LVDT feedback signal deviates from specified limits, a fault is triggered. If the regulator associated with the LVDT has two sensors, the faulty sensor is removed from the feedback calculation, and the remaining sensor is utilized.
What happens if any of the above signals become unhealthy?
When any of the aforementioned signals become unhealthy, a composite diagnostic alarm labeled L DIAG VSVO is generated. Detailed information regarding individual diagnostics is accessible through the toolbox. These diagnostic signals can be individually latched and reset using the RESET DIA signal once they return to a healthy state.
What information does Connector JR1 on the terminal board provide?
Connector JR1 features its own ID device, which is interrogated by the I/O board. This read-only chip contains essential information such as the terminal board's serial number, board type, revision number, and connector location. If a mismatch is detected between the chip data and the expected values by the VSVO, a hardware incompatibility fault is generated.
