ABB NTU-7Q2E Relay Termination Unit

ABB NTU-7Q2E Relay Termination Unit

Basic Information

Model and name: ABB NTU-7Q2E Relay Termination Unit, where ‘NTU-7Q2E’ is the specific model number that clearly identifies this ABB relay terminal unit.

Series: Belongs to the ABB Bailey Infi 90 series of products, which is designed for industrial automation control systems, and can work in conjunction with other series of products to provide precise control and monitoring functions for a variety of equipment in the industrial production process.

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. For example, in an industrial control system containing a variety of electrical equipment, it can convert the weak electrical signals collected by sensors into relay contact signals in order to control higher-power equipment, while isolating the electrical connection between sensors and control equipment to prevent interference.

Multi-channel control: With multiple relay channels, multiple devices or circuits can be controlled at the same time, reducing the number of relays used in the system and lowering the cost and installation space. Common 16-channel configurations can meet the demand for parallel control of multiple signals in complex industrial control systems.

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. For example, normally open, normally closed or changeover contact relays can be selected to meet the control requirements of different circuits.

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

Communication function: Some models support communication protocols, such as Modbus TCP/IP, etc., which can realise network communication and data exchange with other automation equipment, facilitating system integration and remote monitoring.

Technical Parameters

Electrical Parameters:

Working voltage: usually support 120V AC/DC and other voltage levels to adapt to different power supply environments.

Input current: The maximum input current is generally 10A, which can meet the input requirements of most industrial control signals.

Output Configuration: The common output configuration is 2 x 12V DC, 10A, which can provide stable DC power for the connected devices.

Relay contact rating: generally 5A @ 24V DC, you can choose the appropriate relay contact capacity according to the actual load conditions to ensure the safe operation of the system.

Relay type: mostly single-pole, double-throw (SPDT) relays, with good versatility and reliability.

Environmental parameters :

Operating temperature range: usually between - 20°C and + 70°C, can work normally in a wide temperature range, adapt to the temperature changes of different industrial environments.

Humidity: Normal operation under 5% to 95% non-condensing humidity, stable operation in humid industrial environments, without affecting performance due to humidity changes.

Protection level: Generally with IP20 protection level, it 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.

Application Fields

Industrial automation production line: It is used to control the starting and stopping, forward and reverse rotation, speed adjustment of various production equipment, such as motor, conveyor belt, valve and so on, to achieve the automation and intelligence of the production process. For example, in the automobile production line, NTU-7Q2E can be used to control the working status of welding robots and the start/stop of conveyor lines to ensure the efficient operation of the production line.

Power system: It can be used for signal control and protection in substations, power plants, etc., such as realising the control and status monitoring of circuit breakers, disconnect switches and other equipment to ensure the safe and stable operation of the power system.

Petrochemical industry: In the petrochemical production process, it is used to control the operation of various pumps, compressors, valves and other equipment, as well as monitoring and controlling the temperature, pressure, flow rate and other parameters in the production process to ensure the safety and stability of the production process.

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

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 automatic control of the treatment process.
