NL-USBG-C-016 - 16-channel IO expander with USB communication (top header)

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.
