Product Advantages and Features

1. Flexible Input Configuration
   Each channel can be independently set to voltage or current mode, adapting to various sensors (e.g., temperature transmitters, pressure transducers) without additional converters.
2. High Accuracy
   12-bit resolution and ±0.5% full-scale accuracy ensure precise signal conversion, meeting the requirements of most industrial process control scenarios.
3. Channel Isolation
   500VAC isolation between channels minimizes cross-interference, ensuring stable signal acquisition in noisy industrial environments (e.g., near motors or inverters).
4. Noise Reduction
   Configurable digital filtering reduces the impact of electrical noise, improving the stability of measured data.
5. Easy Integration
   Plug-and-play design with DirectLogic series PLCs simplifies installation. No complex wiring is required, reducing setup time.

Application Areas

1. Process Control
   Used in chemical, food processing, and water treatment industries to collect signals from temperature, pressure, and flow sensors for closed-loop control.
2. Energy Management
   Monitors voltage, current, and power signals in power distribution systems to optimize energy usage and prevent overloads.
3. Manufacturing Automation
   Integrates with position sensors, load cells, and speed transducers to provide feedback for precision machinery (e.g., CNC machines, robotic arms).
4. Environmental Monitoring
   Collects data from humidity sensors, gas detectors, and level transmitters in environmental protection systems.
5. Building Automation
   Connects to HVAC sensors (temperature, air pressure) to regulate heating, ventilation, and air conditioning systems.

Precautions

1. Wiring
   • Use shielded twisted-pair cables for analog signals. Keep them separate from high-voltage power cables to avoid electromagnetic interference.
   • Ensure proper grounding of cable shields (single-point grounding) to reduce noise.
2. Signal Matching
   • Confirm that the sensor output range matches the module’s configured input range (e.g., 4-20mA sensors must correspond to the 4-20mA input setting).
   • Avoid exceeding the maximum input voltage/current limits to prevent module damage.
3. Power Supply
   • Use a stable 24VDC power supply with low ripple (≤100mV) to ensure measurement accuracy.
   • When multiple modules are installed, check that the total power consumption does not exceed the PLC base’s capacity.
4. Environmental Protection
   • Install the module in a dust-free, dry control cabinet. Avoid exposure to corrosive gases or extreme temperatures (above 55°C).
5. Calibration
   • Calibrate the module periodically using standard signal sources to maintain measurement accuracy. Refer to the user manual for calibration procedures.
