Product Features
ABB NAIO-02 supports fixed bipolar signals, including ±0 (4)~20mA current signals, ±0 (2)~10V voltage signals, and ±0~2V voltage signals, meeting the requirements for analog signal acquisition in both positive and negative directions.
ABB NAIO-02 provides two channels of 0 (4) to 20 mA current output, capable of driving external actuators (such as valves or speed control valves), with a load resistance of ≤700 Ω.
ABB NAIO-02 input uses 11-bit data bits + 1-bit sign bit A/D conversion (bipolar mode), and the output is 12-bit D/A conversion, with an accuracy of ±0.5% of full scale (at 25°C), ensuring the accuracy of signal acquisition and control.
ABB NAIO-02 can be connected to the NAMC board of the ACS 600 variable frequency drive via a fiber optic link, supporting a transmission rate of 1 Mbit/s. It functions as a slave station within the DDCS ring network, with data periodically polled by the master station (NAMC).
Inputs, outputs, power supply, and ground are designed with isolation (test voltage: 1.5 kV AC/1 minute), offering strong resistance to electromagnetic interference and suitability for industrial environments with high noise levels.
ABB NAIO-02 can be configured with a unique node number (0–127) via a 7-bit DIP switch, ensuring conflict-free communication with other modules within the DDCS ring network.
Product Application
ABB NAIO-02 can be applied to industrial production lines, pump and fan systems, crane equipment, process control, and other fields.
Industrial production lines:
Expand the analog interface of the ACS 600 variable frequency drive to collect process parameters such as temperature and pressure from the production line, and output control signals to adjust the speed of the conveyor belt or the operating status of the equipment.
Pump and Fan systems:
Monitor pipeline pressure/flow through analog inputs, and output signals to control the speed of pumps or fans to achieve closed-loop regulation.
Crane equipment:
In conjunction with the ACS 600 Crane Drive, collect analog signals from load sensors, output control signals to adjust lifting speed, and ensure safe operation.
Process control:
In chemical and metallurgical applications, expand the collection and control of analog parameters such as liquid level and concentration, and collaborate with the variable frequency drive to achieve precise process regulation.
