Model and system: Model NLMM02 for ABB Bailey Infi 90 and Net 90 systems.

Functional features

Powerful Logic Processing Capability: As a logic main module, it can efficiently perform various logic operations and control functions, such as the processing of logic instructions for and, or, non, timer, counter, etc. It can judge and process the input signals according to the logic program written by the user, and quickly and accurately output the control signals, so as to achieve the precise control of the equipment and process flow in the industrial production process.

Multi-channel input/output support: usually with multiple input/output channels, it can be connected to multiple external devices or sensors at the same time to achieve the acquisition and processing of a variety of signals, such as digital input/output, analogue input/output, etc., which makes it convenient to be integrated and communicated with different types of industrial equipment.

Real-time monitoring and diagnostic function: real-time monitoring of the module's own working status, the status of the input and output signals and the operating status of the equipment connected to it, once abnormalities are found, such as loss of signals, equipment failures, etc., it can send out alarm signals in time and provide detailed diagnostic information to help maintenance personnel to quickly locate and solve problems, and to improve the reliability and stability of the system.

Flexible programming and configuration: Supporting a variety of programming languages and programming methods, such as ladder diagrams, statement tables, function block diagrams, etc., users can choose and write programmes according to their own habits and specific control needs. Meanwhile, the configuration parameters of the module can be flexibly set through special programming software or human-machine interface, which is convenient for users to customise the configuration according to the actual application scenarios.

Technical Parameters

Input and output characteristics: input channels are usually 16, the input voltage range is 24V DC, response time ≤ 5ms; the number and type of output channels vary according to the specific models, which can meet different load requirements.

Working environment: the working temperature range is - 20 ℃ to + 60 ℃, the relative humidity range is generally 10% to 90% (non-condensing), able to work stably in a relatively harsh industrial environment, the protection level is generally IP20, can prevent the entry of solid objects with a diameter of more than 12.5mm.

Communication interfaces: Equipped with a variety of communication interfaces, such as Ethernet interfaces, serial interfaces, etc., it supports the internal communication protocols of the Net 90 system as well as common industrial communication protocols, such as Modbus RTU and TCP modes, so as to realise fast and stable communication with other devices or systems.

Application Areas

Manufacturing automated production lines: In automated production lines of automobile manufacturing, machining, electronic production and other industries, it can be used to control the start and stop of production equipment, operation sequence, fault alarms, etc., such as the movement control of robots in automated assembly lines, the conveyor belt on the conveyor belt, etc., to improve the production efficiency and product quality, and reduce the cost of labour and intensity of labour.

Process control system: In chemical, petroleum, electric power, pharmaceutical and other process industries, real-time monitoring and control of temperature, pressure, flow, liquid level and other parameters in the production process, such as temperature control of chemical reactor, refinery flow regulation, boiler water level control in power plants, etc., to ensure the safe, stable and efficient operation of the production process.

Intelligent building automation system: In the HVAC system, lighting system and lift system of intelligent buildings, intelligent control and management of building equipment is achieved, such as automatic adjustment of air conditioning operation mode according to indoor and outdoor temperatures, automatic control of lighting switching and brightness according to the intensity of light, and group control management of lifts, so as to improve the building's energy use efficiency and comfort.
