ABB NTPL01 Plant Loop Termination Unit

ABB NTPL01 Plant Loop Termination Unit

Technical Parameters

Power supply: the working voltage is 24V DC, the power supply current is 120mA.

Dimensions and weight: dimensions of about 15.00cm × 10.00cm × 3.00cm, weight 1.25kg.

Functional Features

Loop connection and termination: The main function is to provide connection and termination points for two factory loops, and to terminate the twin-axis cable when connecting a loop interface module such as IN LIM03 to ensure the correct transmission of loop signals and stable operation of the system.

Signal Isolation: Effectively isolates the communication signals between the factory loop and other equipment such as electronic components within the PCU, preventing signal interference and noise effects and improving the quality and reliability of signal transmission.

Grounding and shielding connection: Provides a place to connect the cable shield, which can be grounded to enhance the anti-interference capability of the system and reduce the impact of external electromagnetic interference on the system.

Application Areas

Industrial automation control system: In chemical industry, electric power, iron and steel and other large-scale industrial automation production lines, it is used to connect the control systems of different regions or different equipments, to ensure reliable communication and data transmission between on-site equipments and the central control system, and to realise stable operation and precise control of the production process.

Process control system: In pharmaceutical, food and beverage, water treatment and other process industries, it is used to connect on-site sensors, transmitters, actuators and other equipment with the monitoring system to achieve real-time monitoring and control of temperature, pressure, flow, liquid level and other parameters in the production process to ensure production quality and safety.

Intelligent building automation system: In intelligent buildings, it can be used to connect various devices in the building control system, such as air-conditioning system, lift system, lighting system, etc., to achieve centralised monitoring and management of building equipment, improve the building's energy efficiency and comfort, and reduce operating costs.

The AC 800F is available in two versions:  

• 4 MB static RAM, 4 MB EPROM  

• 16 MB synchronous dynamic RAM,   8 MB EPROM

The AC 800F optionally provides several levels  of redundancy: 

• device redundancy with 2 AC 800F  

• power supply redundancy (24 V DC)  

• Ethernet communication redundancy   (standard)  

• Cable redundancy for Profibus DP,   requires external equipment (RLM01)

AC 800F Controller Redundancy

Controller redundancy can be achieved by installing two  AC 800F. To ensure quick and smooth takeover by the secondary AC 800F in case the primary AC 800F fails, a dedicated  redundancy communications link through the second Ethernet  module makes sure that both AC 800F are always synchronized. All inputs and outputs are designed to support redundant  operation.

Product Benefits

Flexible Configuration:

Supports a variety of configuration options, which can be configured to different input or output modes according to specific application requirements to meet different control needs.

High performance:

Featuring fast response and high accuracy, it can monitor and control digital signals in real time to ensure the stability and reliability of the system.

Equipped with an on-board 100Mbit/s Ethernet connection, communication between the controller, operator station and engineering workstation is faster and more reliable.

Modular design:

Adopting modular design, it is easy to install, maintain and expand, and can flexibly cope with control systems of different scale and complexity.

Communication interface:

Support common communication interfaces, such as Profibus, Modbus, etc., which can exchange data and communicate with other devices and systems.

Reliable and stable:

As a well-known brand of industrial automation, ABB's products have excellent quality and stability, ensuring stable operation of the equipment for a long time.

Memory & Security:

With 10MB of memory, of which 2MB is for battery backup, to ensure the safety of data and stable operation of the system.

Provides a key lock function to prevent unauthorised downloading of applications and firmware by locking the controller, enhancing the security of the system.

Compact Front Panel Display:

Equipped with a small front panel display that visually shows status and diagnostic information for easy monitoring and maintenance of the unit.
