- Functional Features:
- 8-channel multi-input design meets the requirement of multi-channel analog signal acquisition in medium-precision industrial process control systems, and the group-based hardware configuration simplifies the parameter setting and adapts to the unified signal type of multiple sensors in the same process link.
- 14-bit moderate resolution and high conversion accuracy balance the requirements of signal acquisition precision and system cost, with high cost performance, suitable for medium-precision industrial control occasions that do not require ultra-high precision.
- Support a variety of universal industrial analog signal types, compatible with most standard field sensors and transmitters, without additional signal conversion equipment, reducing the system configuration cost and wiring complexity.
- 2500 VAC high-voltage isolation between channels and backplane bus effectively suppresses the interference of the PLC system on the collected analog signals, and the intra-group isolation ensures the relative independence of channel signals, improving the signal acquisition stability.
- Built-in signal conditioning circuit with high CMRR and NMRR filters out industrial field common-mode and normal-mode interference, improves the signal-to-noise ratio of collected signals, and ensures the accuracy of analog signal acquisition in general industrial environments.
- Fast conversion time and batch sampling function realize real-time collection of multi-channel analog signals, providing timely data support for industrial process control and ensuring the real-time performance of the control system.
- The module is equipped with overall LED status indicators (power, normal, fault) and group-level signal overrange indicators, realizing visual monitoring of the module working status and signal acquisition faults, facilitating quick troubleshooting of system faults.
- Screw terminal wiring method with clear channel marking ensures firm and reliable wiring, reduces wiring errors, and is convenient for on-site installation and maintenance, adapting to the harsh wiring environment of the industrial field.
- Fully compatible with AEG Modicon 800 series PLC chassis and backplane bus, plug-and-play, and can be flexibly combined with digital I/O modules, communication modules and other analog modules to form a complete medium-precision industrial control system.
- Application Scenarios: Widely used in medium-precision industrial process control systems with multi-channel analog signal acquisition requirements such as building central air conditioning temperature and humidity control, water treatment plant multi-point water quality parameter collection, food production line process temperature and flow control, and mechanical processing equipment running state monitoring. It is also applied in small and medium-sized factory automation production lines and municipal engineering control systems, and is suitable for all industrial occasions that require cost-effective multi-channel analog signal acquisition and medium-precision process control.
