ABB NTU-7C6/MO Termination Unit

ABB NTU-7C6/MO Termination Unit

Basic Information

Model and name: ABB NTU-7C6/MO Termination Unit, ‘NTU-7C6/MO’ is the specific model number of this product. The NTU-7C6/MO Termination Unit, ‘NTU-7C6/MO’ is the specific model of this product. It is a termination unit produced by ABB and belongs to an important part of its industrial automation product line.

Functional Characteristics: It is mainly used to terminate, match, convert and distribute signals to ensure the accurate transmission of signals and the reliable operation of equipment in industrial automation control systems, and is often used in conjunction with other control modules, input and output modules, etc., to realise complete control functions.

Functional characteristics

Signal processing function

Termination and matching: It can effectively terminate the input signals to prevent signal reflection and interference, and at the same time match the impedance and other characteristics of the signals to make the signals meet the requirements of the system and ensure the quality and accuracy of signal transmission.

Conversion and distribution: It can convert the received signals of different formats or levels into standard signals that can be processed by the internal modules, and accurately distribute these signals to the corresponding control channels or function modules, so as to realise the precise control of industrial equipment.

Isolation Protection Function

Electrical isolation: provide reliable electrical isolation between signal input and output, its isolation voltage level can meet the demand of high voltage interference environment in the industrial field, generally up to thousands of volts, effectively preventing external high voltage interference signals from entering the control system, and at the same time, avoiding the abnormal signals triggered by internal faults from damaging the external equipment.

Function module isolation: different control function modules are isolated so that they can operate independently without interfering with each other. Even if a function module fails, it will not affect the normal work of other modules, which enhances the overall reliability and stability of the system.

Technical Parameters

Electrical parameters

Working voltage range: usually with a wide range of working voltage to adapt to different industrial power supply conditions, such as 18V - 30V DC, etc., to ensure that in a variety of power conditions can work stably.

Isolation Voltage Level: Generally between 1500V - 3000V AC, high isolation voltage can effectively guarantee the safety and stability of the system in complex electrical environments.

Power Consumption: The overall power consumption is in a reasonable range, usually between 10W - 30W, the specific power consumption may vary depending on the working condition of the equipment and the load situation.

Performance Parameters

Signal Processing Accuracy: In the process of signal conversion and processing, it has high accuracy to meet the requirements of industrial control on signal accuracy, such as analogue signal conversion accuracy can reach 0.1% - 0.5%.

Number and type of channels: it has multiple signal channels, the number of channels may be between 2 - 4, these channels can be digital signal channels or analogue signal channels to meet the transmission and processing needs of different types of signals.

Environmental parameters

Operating temperature range: able to work normally in a wide temperature range, generally -20℃ - +70℃, some models may support a wider temperature range, can adapt to a variety of harsh industrial environments.

Humidity range: Relative humidity range is usually 5% - 95% (non-condensing), stable operation in humid industrial environments, unaffected by changes in humidity.

Protection level: High protection level, such as IP20 - IP30, can effectively prevent the intrusion of foreign objects and personnel accidental contact with the internal circuit, to protect the safety and reliability of the equipment.

Fields of application

Chemical industry: In the process of chemical production, it is used to control various parameters of chemical reaction, such as temperature, pressure, flow, etc. Signal processing and transmission to ensure the safe and stable operation of chemical production.

Power system: It can be used in the automatic control of substation, monitoring voltage, current and other power parameters and controlling the transmission of signals to ensure the reliable power supply of the power system.

Oil and gas extraction industry: It plays an important role in wellhead equipment control and pipeline monitoring, processing and transmitting relevant signals to ensure efficient and safe oil and gas extraction.
