3. Advantages and Features
- High Reliability: Having passed extensive field tests, Woodward 9907-164 can operate stably in harsh industrial environments. For example, in a steel plant where there are strong vibrations and electromagnetic interferences, it has maintained stable operation for over 3 years without significant failures, ensuring the continuous operation of the turbines.
- Rich Functionality: It comes with standard functions such as critical speed avoidance, valve limiters, automatic start-up sequences, and trip first-out indicators. These functions enhance the safety and efficiency of turbine operation. For instance, the critical speed avoidance function can prevent the turbine from operating at speeds that may cause mechanical resonance, thus protecting the turbine components.
- Flexible Configuration: With 12 programmable contact inputs out of 16 and 6 programmable current inputs, Woodward 9907-164 can be customized according to different user requirements. In a power generation project, users were able to program the inputs to meet the specific control needs of the steam turbine, improving the overall control accuracy.
- User-friendly Operation: Equipped with a 30 multifunctional keyboard and a two-line, 24-character display, along with menu-driven software, it is convenient for field operators to configure. Even operators with limited technical knowledge can quickly master its operation, reducing the learning cost and improving work efficiency.
4. Application Areas and Application Cases
- Application Areas: Widely applied in the power industry for steam turbine power generation systems, as well as in industries such as petrochemicals, metallurgy, etc., where steam turbines, turbogenerators, and turbine expanders are involved in the control scenarios.
- Application Case: In a large-scale petrochemical plant, Woodward 9907-164 was used to control the steam turbines that drive various pumps and compressors. By precisely controlling the speed of the turbines through this module, the plant was able to optimize the operation of these equipment. The energy consumption was reduced by about 15%, and the production efficiency was increased by 20%. Moreover, due to its reliable performance, the maintenance frequency of the turbines was significantly reduced, saving a large amount of maintenance costs.
5. Comparison with Competitors
6. Selection Suggestions
- Compatibility: Ensure that Woodward 9907-164 is compatible with existing steam turbines, actuators, and other related equipment in terms of electrical interfaces and communication protocols. Check whether the input and output signals match the requirements of the connected devices.
- Installation Environment: Consider the available installation space and the environmental conditions, such as temperature, humidity, and vibration. Although it can operate in a wide temperature range, it is still necessary to ensure that the installation environment does not exceed its specified limits. If the installation site has strong vibrations, appropriate shock absorption measures should be taken.
- Function Requirements: Based on the actual control needs, such as the need for precise multi-parameter control and specific protection functions, evaluate whether Woodward 9907-164 can meet these requirements. For example, if you need to control the turbine’s speed with high precision, make sure the module’s control accuracy can meet your needs.
- Budget: Consider the product price, maintenance cost, and the potential benefits it can bring in combination with the project budget. Although Woodward 9907-164 may have a relatively higher initial cost, its long-term reliability and energy-saving effects can offset this cost to a certain extent.
7. Precautions
- Installation: When installing, strictly follow the installation manual to ensure correct wiring and avoid short circuits or reverse connections. Pay attention to the vibration and electromagnetic interference at the installation location. If necessary, take shock absorption and shielding measures. Make sure to install it in a location that is convenient for operation and maintenance.
- Operation: Regularly check the operation status of the module and look for any alarm messages or abnormal indicator lights. Avoid using it in environments that exceed the specified temperature, humidity, and other conditions. If any abnormalities are found, stop using it immediately and carry out troubleshooting.
- Maintenance: Have professional personnel perform maintenance. When performing inspections and component replacements, ensure that the power is turned off first and take anti-static measures. Regularly clean the module to prevent dust and debris from affecting its performance.
BENTLY 3500/42M 176449-02
Expanded channel capacity: With 16 input and 16 output channels, the 3500/42M 176449-02 can handle multiple sensor types across large machinery or entire process lines. This capacity allows it to process signals from numerous 87199-01 sensors (via 135799-01 amplifiers) and thermocouples simultaneously, reducing the need for multiple modules and simplifying system integration.
Superior signal processing: Equipped with 24-bit ADC resolution and a wide filtering range (0.01Hz to 20kHz), the module delivers exceptional measurement accuracy and noise reduction. This high resolution ensures that subtle signal variations from 87199-01 sensors—amplified by the 135799-01—are preserved, enabling early detection of machinery issues such as bearing wear or rotor imbalance. The configurable filters allow optimization for specific sensor types and operating conditions.
Direct thermocouple support: Unlike basic modules, the 3500/42M 176449-02 natively supports 7 thermocouple types (J, K, T, E, R, S, B), eliminating the need for external transmitters. This integration reduces signal loss and potential points of failure, while the module’s cold junction compensation ensures accurate temperature measurement even in varying ambient conditions.
Enhanced connectivity and remote access: The integrated Ethernet port enables remote configuration via 170180-01-00 software, eliminating the need for on-site access during setup or adjustments. It supports real-time data streaming to cloud platforms or SCADA systems, enhancing visibility in distributed facilities. The RS-485 port allows daisy-chain communication with other modules, simplifying wiring in large installations.
Advanced isolation: With 5kVrms channel-to-channel and channel-to-backplane isolation, the module provides superior protection against ground loops, voltage transients, and electrical interference—critical in high-voltage industrial environments. This isolation ensures measurement integrity when processing signals from 135799-01 amplifiers and thermocouples, even in noisy environments like power plants and steel mills.
