ABB NLIS01 Loop Interface Slave

ABB NLIS01 Loop Interface Slave

Basic Information

External dimensions: length approx. 12.7cm, width 5.1cm, height 12.7cm, weight approx. 0.1kg, origin Sweden.

Model and system: Model NLIS01 for ABB Bailey Infi 90 and Net 90 systems.

Functional features

Realisation of network communication interface function: as a loop interface slave, it is mainly responsible for realising communication connection with other devices or modules in the loop of Net 90 system, ensuring reliable data transmission in the network, enabling different devices to exchange information and work together, and is an important part of the system to realise distributed control and centralised management.

Signal Conversion and Processing: It can convert and process the input and output signals, such as converting the analogue or digital signals from the field devices into the format that can be transmitted by the network, and at the same time, it can also convert the signals received from the network into the signals that can be recognised by the field devices, which realises the signal matching and interaction between the field devices and the control system.

Support a variety of communication protocols: compatible with the Net 90 system internal communication protocols and other common industrial communication protocols, such as communication and integration with a variety of different brands and models of PLC, DCS systems, etc., which is convenient for the user to flexibly select and expand in the existing industrial automation system.

It has certain diagnostic function: it can monitor its own working status and the status of the communication link in real time, and when there is a communication failure, signal abnormality, etc., it can prompt the operator through the corresponding indicator or diagnostic information, which can help to locate and solve the problem quickly, reduce the downtime of the system, and improve the availability and reliability of the system.

Technical Parameters

Power Requirements: Normally requires +5V DC and ±15V DC power supply, power consumption is 10VA.

Communication rate: Support 10 megabaud communication rate, which can meet the real-time data transmission requirements of most industrial sites.

Application Fields

Industrial automation control system: In the automation control system of chemical, petroleum, electric power, metallurgy and other industries, it is widely used in process control, equipment monitoring, data acquisition, etc., such as production process monitoring of oil refineries, unit control of power plants, blast furnace automation control of iron and steel mills, etc., which realises precise control and optimal management of complex industrial production processes.

Intelligent building automation system: In the HVAC system, lighting system and security system of intelligent buildings, it is used to achieve communication and cooperative control between different subsystems, such as automatically adjusting the operation mode of the air conditioning system according to indoor and outdoor environmental parameters, realising the intelligent control and energy-saving management of the lighting system, and linking up with the security system to realise the safety control in case of emergencies, etc., which improves the level of intelligence of buildings and the efficiency of energy use. Energy utilisation efficiency.

Water treatment and environmental protection industry: In urban water supply, sewage treatment, waste gas treatment and other systems, it is used to monitor and control the operation status of water treatment equipment, collection and transmission of water quality parameters, remote monitoring and management of environmental protection equipment, etc., to ensure the safe, stable and highly efficient operation of water treatment and environmental protection processes, and to achieve effective protection of the environment and rational use of resources.
