- Functional Features:
- 12-bit high resolution and ultra-high output accuracy ensure the precise conversion of PLC digital control signals into analog signals, meeting the requirements of high-precision regulation of single process parameters such as pharmaceutical production line material flow and semiconductor manufacturing process temperature.
- Ultra-low temperature drift and time drift (≤20 ppm/°C, ≤0.01% FS/year) ensure the long-term stable output of the analog signal, without frequent calibration, reducing the daily maintenance work of the system and ensuring the long-term stability of industrial process control.
- Support seamless software configuration and switching between 4-20 mA current and 0-10 VDC voltage output signals, adapting to different types of field precision actuators, with strong flexibility and compatibility.
- 3000 VAC high-voltage two-way isolation effectively suppresses the electromagnetic interference of the industrial field and the PLC system on the output analog signal, prevents the high voltage of the field actuator from feeding back to the PLC system, and ensures the safety and stability of the analog output signal in harsh interference environments.
- Ultra-fast conversion time (≤1 ms) realizes real-time conversion of PLC digital control signals into analog signals, providing timely and accurate control signals for field actuators, meeting the high real-time requirements of industrial process control for precise regulation.
- Strong output load capacity adapts to various field precision actuators with different load impedances, can directly drive electric regulating valves, precision frequency converters and other actuators without additional signal amplifiers, simplifying the system circuit structure and reducing the configuration cost.
- Built-in output short-circuit and overcurrent protection functions automatically limit the output current when the load is short-circuited or overloaded, effectively protecting the module and field actuators from damage, and the protection functions are self-recovering after the fault is removed.
- LED status indicators for power on (green), output normal (yellow) and fault (red) realize visual monitoring of the module working status and output signal status, facilitating quick troubleshooting of module and actuator faults.
- Compact narrow width design saves the installation space of the industrial control cabinet, and the standard DIN rail mounting design is convenient for on-site installation and disassembly, suitable for installation in the control cabinet with limited space and for combination with other PLC modules.
- Fully compatible with AEG Modicon 800/900/984 series PLC systems, plug-and-play, no additional driver software required, and the output signal parameters can be configured online through the PLC programming software, with simple and intuitive operation.
- Application Scenarios: Widely used in industrial process control systems that require high-precision single-channel analog control such as pharmaceutical production line single-point material flow precision regulation, semiconductor manufacturing process single-point temperature precise control, aerospace component processing single-point pressure regulation, and laboratory industrial test equipment single-parameter precise control. It is also applied in food and beverage production line single-point liquid level precise regulation and chemical plant single-point reaction pressure precise control, and is suitable for all industrial occasions that require high-precision, long-term stable and real-time regulation of a single process parameter.
