ABB NTCL01 Communication Link Termination Unit

Basic Information

Dimensions: Net depth/length is 96.52mm, net height is 236.22mm, net width is 220.98mm, weight is about 3kg.

Power Requirements: Operating voltage is 24V DC, maximum current is 19.7mA, typical current is 15.8mA.

Operating environment: Operating temperature range of 0°C to 70°C, relative humidity of 5% to 90% (±5%) up to 55°C, relative humidity of 5% to 40% (±5%) at 70°C, and non-corrosive environment.

Functionality

Signal transmission and conversion: Acts as a connection point in the Infi-net network, transmitting and converting electrical signals to ensure efficient data communication between different devices.

Communication protocol support: Supports ABB Bailey's proprietary Infi-net protocol, which is used to realise communication between various devices in ABB Bailey's process control system.

Status indication: With status output function, it can display ON/OFF status, which is convenient for users to know the working status of the communication link in real time.

Working Principle

In the Infi 90 and Net 90 series control systems, NTCL01 is connected to other devices through specific interfaces, such as the network interface module INNIS01 and NKSLO1. It receives signals from other devices, converts them into a signal format suitable for transmission in the Infi-net network, and transmits them to other devices over the network. It also checks and filters the received signals to ensure the accuracy and integrity of the signals. In case of communication failure or abnormality, NTCL01 will carry out corresponding processing, such as sending alarm signals, automatically switching to the backup communication link, and so on.

Application Scenarios

Industrial automation production line: In automation production line, it is used to connect various automation equipments, such as PLC, sensors, actuators, etc., to achieve fast and stable communication between equipments, and to ensure efficient operation and automation control of production line.

Power system: in power plants, substations and other power systems, it can be used to connect power monitoring equipment, protection devices, automation control systems, etc., to realise real-time monitoring, fault diagnosis and automation control of the power system, and to ensure the safe and stable operation of the power system.

Oil and gas refineries: used to connect process control equipment, sensors, analysers, etc., to achieve precise control and optimisation of the refining process, improve production efficiency and product quality.

Water treatment facilities: in water treatment plants, water quality monitoring sensors, automated control equipment, etc. can be connected to achieve automated monitoring and optimisation of the water treatment process to ensure that the water quality meets the standards.

OTHER INFORMATION

• Read the safety precautions carefully. 

• Check the delivery for transportation damage. If damage is found, notify the  supplier as soon as possible. 

• Do not use the operator panel in an environment with high explosive hazards. 

• The supplier is not responsible for modified, altered or reconstructed  equipment. 

• Use only parts and accessories manufactured according to specifications of the  supplier. 

• Read the installation and operating instructions carefully before installing,  using or repairing the operator panel. 

• Never allow fluids, metal filings or wiring debris to enter any openings in the  operator panel. This may cause fire or electrical shock. 

• Only qualified personnel may operate the operator panel. 

• Storing the operator panel where the temperature is lower/higher than  recommended in this manual can cause the LCD display liquid to  congeal/become isotopic. 

• The LCD display liquid contains a powerful irritant. In case of skin contact,  wash immediately with plenty of water. In case of eye contact, hold the eye  open, flush with plenty of water and get medical attention.
