ABB NBIO-21C

Details

ABB NBIO-21C modules are widely used in industrial automation.

Working parameters

Voltage range: NBIO-21C recommended operating voltage range: 24-32 VDC; minimum extended operating voltage range: 20-36 VDC; overvoltage protection: <42.5 VDC. Output current range: Each module contains up to six output channels; the output current of points 2, 3, 4, 6, 7, and 8 is between 4-20 mA; points 1 and 5 can output currents in the range of 20-320 mA.

Output accuracy: Within the operating range, the output accuracy of NBIO-21C is within 0.25%; it has very good accuracy in the range of 0° to 60°C; load: According to the variable voltage, the following load capacity can be achieved. For example, when the analog signal output is 20VDC 4-20mA, the load corresponding to the analog signal output is ≤275Ω, 20-320mA output is ≤275Ω, and the relationship between the load corresponding to the output and the external loop voltage is ≤15Ω; ≤475Ω, ≤25Ω at 24VDC, etc. Overrange capability: 4-20mA output overrange is 2-21.2mA (overrange + 6%) FSR. 20-320mA output overrange is 20-339.2mA (overrange + 6%) FSR. The resolution is 12-bit resolution, and the output analog signal is more accurate.

Product Features

High accuracy: NBIO-21C has an output accuracy of less than 0.25%, which can achieve precise control and regulation of various variables such as temperature, pressure, flow, etc. in industrial processes, ensuring the accuracy and stability of industrial production. Multi-output configuration: 6-channel output facilitates simultaneous control/coverage of multiple devices or loops, thereby reducing the number of modules while limiting the complexity and cost of the system.

Wide voltage adaptability: 20-36VDC voltage range, can work stably in different power supply environments. This function enhances the adaptability and reliability of the system, making it advantageous in some environments with large power supply fluctuations (such as some industrial sites). Overvoltage protection function: Overvoltage protection less than 42.5VDC can effectively prevent the abnormal increase of power supply voltage from damaging the module, thereby improving the service life and safety of the module.

Application range

Industrial automation control system: NBIO-21C can be applied to various industrial automation production lines such as chemical, petroleum, natural gas, pharmaceutical, food, and beverage. As a key analog output module in the control system, it can achieve precise control of various parameters in the production process.
