- Functional Features:
- 16-bit high resolution and ultra-high conversion accuracy ensure the collection of tiny analog signal changes from precision sensors, meeting the requirements of high-precision industrial process control such as pharmaceutical and semiconductor manufacturing.
- Each channel supports independent software configuration of signal types and ranges without hardware jumpers, enabling flexible adaptation to different field sensor signal outputs and simplifying on-site debugging.
- 3000 VAC high-voltage three-way isolation effectively suppresses industrial field electromagnetic interference, prevents fault spread between channels, and ensures the stability and accuracy of signal acquisition in harsh interference environments.
- Ultra-fast conversion time and synchronous sampling function realize real-time and synchronous collection of multi-channel analog signals, providing accurate and real-time data support for multi-parameter collaborative control of industrial processes.
- Built-in high-performance signal conditioning circuit with high CMRR and NMRR effectively filters out common-mode and normal-mode interference in the industrial field, further improving the signal-to-noise ratio of collected signals.
- Each channel is equipped with independent LED status indicators (normal, overrange, fault), realizing visual monitoring of signal acquisition status and facilitating quick troubleshooting of sensor and wiring faults.
- Supports hot swapping function, which allows module replacement without shutting down the PLC system, effectively reducing production line downtime and improving system maintainability.
- Fully compatible with AEG Modicon 800 series PLC chassis and backplane bus, plug-and-play, and can be flexibly combined with other I/O modules to form a complete high-precision control system.
- Application Scenarios: Widely used in high-precision industrial process control systems such as pharmaceutical production line material proportioning control, semiconductor manufacturing process temperature and pressure control, aerospace component processing precision detection, and laboratory industrial test equipment signal acquisition. It is also applied in food and beverage production line high-precision flow control and chemical plant fine reaction process parameter collection, and is suitable for all industrial occasions that require ultra-high precision analog signal acquisition and processing.
