8-channel analog acquisition module with default current measurement mode (0–20 mA), designed for industrial applications requiring stable and precise data acquisition. Compatible with current sensors, it supports RS485 communication and the Modbus RTU standard, allowing easy integration with SCADA systems and PLC controllers. Galvanic isolation and noise immunity make it suitable for environments with high EMC requirements. Ideal for industrial process monitoring, environmental parameter measurement, and building automation.
Description
8-channel industrial module for analog signal acquisition using the Modbus RTU standard, designed for current input in the 0–20 mA range. Supports RS485 communication and simultaneous acquisition from multiple channels. A built-in digital filtering algorithm with oversampling increases signal stability. Wide input voltage range (7–36 V DC) and dual galvanic isolation—for both power and signals—ensure high reliability in industrial environments. The module includes surge, overcurrent, and electrostatic discharge protection, making it resistant to interference. DIN rail mounting facilitates integration with existing control infrastructure.
Properties
- 8-channel analog current signal acquisition (default 0–20 mA)
- RS485 communication, Modbus RTU protocol
- 12-bit resolution, accuracy ≤3%
- Data update rate: 25 Hz
- Configurable inputs: differential or single-ended
- Configurable device address (1–255)
