Technical Parameters

Input and output parameters

Number and characteristics of input channels: The number of input channels is generally between 8 and 32, depending on the device model. Each input channel is capable of receiving standard digital level signals such as TTL (Transistor-Transistor Logic) levels or CMOS (Complementary Metal-Oxide-Semiconductor) levels. The frequency range of the input signals can cover from direct current (DC) to higher frequencies, and are typically capable of handling digital signals from a few Hertz to tens of kilohertz to accommodate the output signals of different types of sensors.

Number and characteristics of output channels: The number of output channels matches the number of input channels or is configured according to the actual application requirements, usually also between 8 - 32. The output channels can provide enough drive capability to control common industrial actuators. For example, the output high or low level signals can directly drive small relays with output currents and voltages capable of meeting the requirements of relay actuation and release, typically with output currents in the range of a few hundred milliamps to several amperes, and output voltages in the appropriate DC voltage range (e.g., 5V - 24V).

Electrical parameters

Operating Voltage and Power Consumption: The operating voltage is generally within the 12V - 24V direct current (DC) range. This voltage range matches the common power supply in industrial sites and facilitates the use of standard industrial power supplies for power supply. In terms of power consumption, under normal operating conditions, power consumption is usually between a few watts and a dozen watts, depending on the use of input and output channels, the complexity of logic operations and other factors. Lower power consumption helps to reduce the energy consumption of the system and the heat dissipation needs of the device.

Communication Parameters

Communication Protocols and Interface Types: A variety of communication protocols are supported, such as Modbus, Profibus, Ethernet/IP, etc. as mentioned earlier. The communication interface types may include RS-485 interface for Modbus and Profibus communication, and Ethernet interface for Ethernet/IP communication; the communication rate of RS-485 interface is generally between 9600bps - 115200bps, while Ethernet interface can support 10Mbps - 1000Mbps communication rate according to the network configuration to meet different data transmission rates. The Ethernet interface can support 10Mbps - 1000Mbps communication rate according to the network configuration to meet different data transmission speed requirements.

Application Scenarios

Industrial automated production lines

Equipment control and coordination: In automated production lines, it is used to control the operation and coordination of various equipment. For example, in an automotive parts production line, by receiving sensor signals from each station, such as signals of parts in place, processing completion, etc., and after logical operations, it controls the movement of robots, the start and stop of conveyor belts and speed, and the start and stop of processing equipment, etc., to ensure that all parts of the production line can work together in an orderly manner and to improve the production efficiency and quality of products.

Fault detection and alarm: It can monitor the operation status of the production line equipment in real time, and send out an alarm signal in time through logical judgment when there is a fault or abnormal situation of a certain equipment. For example, when the motor is overloaded, the conveyor belt runs out of alignment or the processing equipment fails, the relevant sensors will send the fault signal to NDLS01, which will trigger the alarm device (e.g. acoustic and visual alarm) after logical processing, and at the same time, it can send the fault information to the upper control system, so as to enable the maintenance personnel to quickly locate and deal with the fault.

Process control system

Process parameter control and interlocking: In the process control system of chemical industry, electric power, water treatment, etc., it is used to control various parameters in the process and realize interlocking protection. For example, in the chemical production process, by receiving digital signals from temperature, pressure, liquid level and other sensors, and utilizing the comparator and logic operation function, it can control the opening of regulating valves, the starting and stopping of pumps, etc., in order to maintain the process parameters within the set range. At the same time, it can also realize the interlock function, such as when the temperature is too high or the liquid level is too low, it will automatically cut off the power supply of the related equipment or start the emergency protection measures to ensure the safety and stability of the production process.

Batch Processing Control: The NDLS01 can be used to control the process of batch processing in industries that require batch production, such as pharmaceuticals, food processing, etc. The NDLS01 can be used to control the process of batch processing. Through the timer and counter function, according to the set time and quantity requirements, the control of raw material placement, processing time, product packaging and other links, to ensure that the quality of each batch of products and the consistency of the production process.
