ABB NTU-7Q2 Relay Termination Unit

ABB NTU-7Q2 Relay Termination Unit

Basic information

Series: belongs to ABB Bailey Infi 90 series products, the series is designed for industrial automation control system, can work with other series products, for industrial production process equipment to provide accurate control and monitoring functions.

Place of origin: Originally from Sweden, some sales channels will be shipped from Xiamen.

Functional features

Signal conversion and isolation: it can convert the input electrical signals into relay contact signals, achieve signal isolation and amplification, effectively protect the control circuit from external interference and over-voltage, over-current, and improve the stability and reliability of the system.

Multi-channel control: With multiple relay channels, it can control multiple devices or circuits at the same time, which reduces the number of relays used in the system and lowers the cost and installation space.

Flexible Configuration: According to different application requirements, the type of relay, contact form and action characteristics and other parameters can be flexibly configured to adapt to a variety of control tasks.

Status Indication: Equipped with status indicator, it can intuitively display the working status of each relay, such as contact closure or disconnection status, which is convenient for users to understand the operation of the system in real time, and to find out the faults and carry out maintenance in time.

Technical parameters

Electrical parameters: Although the specific parameters may vary slightly depending on the specific model and application scenario, generally speaking, its operating voltage, input current, relay contact ratings and other parameters can meet the common needs of industrial control. For example, the operating voltage usually supports a variety of levels to adapt to different power supply environments; relay contact ratings are generally stable under a certain current and voltage, according to the actual load conditions to select the appropriate relay contact capacity to ensure the safe operation of the system.

Environmental parameters: the working temperature range is generally wider, usually between - 20°C and + 70°C, which can work normally in the harsh industrial environment under changing temperature conditions; humidity, it can operate normally under 5% to 95% non-condensing humidity conditions, which can adapt to the humid industrial environment; the protection level is generally IP20, which can prevent the intrusion of foreign objects and prevent people from accidentally touching the internal circuit, to ensure the safety and reliability of the equipment. protection class is IP20, which can prevent the intrusion of foreign objects and prevent personnel from accidentally contacting the internal circuit, guaranteeing the safety and reliability of the equipment.

Application Fields

Industrial automation production line: used to control the start and stop, forward and reverse, speed adjustment of various production equipment, such as motors, conveyor belts, valves, etc., to achieve the automation and intelligence of the production process.

Power system: It can be used for signal control and protection in substation, power plant, etc., such as realising the control and status monitoring of circuit breaker, disconnecting switch and other equipments to ensure the safe and stable operation of power system.

Petrochemical industry: in the petrochemical production process, used to control a variety of pumps, compressors, valves and other equipment, as well as the production process of temperature, pressure, flow and other parameters for monitoring and control, to ensure the safety and stability of the production process.

Pharmaceutical industry: in the pharmaceutical production equipment, such as fermentation tanks, centrifuges, filling machines, etc., control and monitoring, to ensure the precise control of the drug production process and quality stability.

Water treatment industry: used to control the operation of water treatment equipment, such as water pumps, fans, dosing devices and other start-stop and adjustment, to achieve the monitoring of water quality and treatment process automation control.
