This module adopts a mature and stable circuit architecture, equipped with high-precision analog-to-digital conversion chips and full-channel isolation design. It is suitable for high-risk continuous production industries such as power, chemical, oil and gas, and metallurgy. It can be installed in standard racks for high-density arrangement and is widely used in real-time process parameter collection scenarios to ensure the precise and reliable data source of the entire control system.

II. Core Functions

It has eight independent signal acquisition channels. The channel parameters can be flexibly configured through the system software. It can be compatible with the mainstream current, voltage, thermal resistance, and thermocouple signal types in industrial sites. No additional signal conversion accessories are required to adapt to various process measurement points such as temperature, pressure, flow, and level. The module adopts sixteen-bit analog-to-digital conversion technology, with fast sampling response speed and high signal restoration accuracy. It can accurately capture dynamic changes in the working conditions and meet the requirements of closed-loop control and precise monitoring.

Each acquisition channel is equipped with an independent electrical isolation structure, effectively blocking on-site ground potential offset, common-mode interference, and transient voltage surges, preventing abnormal external signals from invading the system internally. The equipment integrates multiple safety protection mechanisms. It can actively protect against overvoltage, overcurrent, line short circuit, polarity reverse connection, static surge, and abnormal high temperature conditions. In fault conditions, it can automatically limit the output and return to normal operation after the anomaly is eliminated. It can operate stably in harsh electromagnetic environments.

The module completes data interaction through the dedicated high-speed redundant bus of Ovation, with low communication transmission delay and good data synchronization. It supports redundant bus links and card main-standby redundant operation modes. When the main working card fails, the standby module can seamlessly take over the acquisition work within milliseconds, without any data interruption or measurement point disconnection issues, minimizing the production risks caused by single-point failures in the acquisition process.

The card panel is equipped with a status indicator light group, corresponding to power supply, operation, fault, and the working status of each channel. On-site personnel can directly determine the module's operating condition. The system end supports remote online fault diagnosis, which can retrieve information such as the module's working temperature, channel acquisition values, fault alarm codes, and communication link status in real time, quickly identify the abnormal points, and reduce the time spent on fault troubleshooting.

It adopts a standard slot-based modular structure, compatible with the Ovation series universal cabinet racks, supports online hot plugging and disassembly operations, and does not require shutting down the entire control system during maintenance, ensuring the normal operation of other channels and associated equipment. The surface of the circuit board is treated with a three-proof coating, with a stable structure and resistance to deformation, capable of adapting to complex on-site environments such as high and low temperatures, humidity, salt fog, vibration, and impact, and has excellent long-term operational stability.

III. Technical Parameters

Six. Installation and Maintenance

When installing, select the standard free slot position inside the cabinet, reserve reasonable up, down, left, and right ventilation and heat dissipation space, and keep away from high-power frequency converters, motors, and other strong heat and strong electromagnetic interference equipment. During the operation process, wear anti-static protective equipment, smoothly push the card into the slot, ensure reliable contact of the back bus, and lock the panel fixing screws. When performing redundant configuration, install two cards of the same specification in adjacent slots to facilitate subsequent wiring and maintenance operations.

For on-site wiring, use shielded twisted-pair cables. The shielding layer of the lines should be grounded at one end according to the specifications to avoid interference from the outside that affects signal acquisition. Clearly distinguish the various signal wiring terminals and connect them according to the corresponding signal types. The wiring terminals should be tightened moderately to prevent loosening and overheating. Arrange the lines neatly to avoid power cables and reduce interference.

Regularly conduct routine inspections to check the status of the module indicator lights, the appearance of the housing, and the wiring areas. Observe for any overheating, loosening, or abnormal deformation. Retrieve the system diagnostic logs to screen potential fault hazards and conduct regular sampling of the accuracy of channel acquisition values. Regularly use a dry soft cloth or low-pressure clean air to clean the accumulated dust on the surface and ventilation positions. In dusty areas, shorten the cleaning cycle appropriately. Do not use corrosive liquids to wipe the equipment.

When the acquisition values are abnormal, check the wiring status of the lines and the operation of the front-end sensing equipment one by one. Combine the system fault codes to determine the root cause of the problem. For communication abnormalities, focus on checking the contact status of the card and the integrity of the bus lines. For module failures, perform online hot swapping for replacement. After the new card is installed, identify the equipment in the system, configure the corresponding channel parameters, test the acquisition function to be normal, and then put it into operation. Dispose of the faulty card and store it in an anti-static sealed container for safekeeping.
