Technical parameters

Input/output specifications

Input channel: It has multiple digital input channels and can be connected to various types of digital signal sources, such as output signals from proximity switches, photoelectric sensors, button switches, etc. The input signal type usually supports DC signals, with a common input voltage range of 24V DC, which is compatible with most industrial sensor output signal standards.

Output channels: Equipped with a corresponding number of digital output channels, used to drive various actuators such as relays, solenoid valves, indicator lights, etc. The output signal is mainly DC signal, and the output current capability varies according to different load types. Generally, it can meet the driving requirements of common industrial actuators. The output current range is, for example, 0.5A-2A, ensuring reliable control of the actuator's action.

Electrical characteristics

Working voltage: The rated working voltage is 24V DC, which enables the module to easily match with the widely used DC power supply in industrial automation systems, ensuring stable power supply in various industrial scenarios and providing a solid foundation for the normal operation of the module.

Signal transmission rate: With a high signal transmission rate, it can quickly transmit input signals to the system for processing, and quickly deliver the processed output signals to the executing device. For example, its signal transmission rate can reach tens of Mbps, which can meet the high real-time requirements of industrial application scenarios, such as the control of high-speed automated production lines.

Physical parameters

Size: The overall design adopts a compact structure, and the module size is small, making it easy to install inside industrial control cabinets or equipment with limited space. The specific dimensions, such as 10cm in length, 8cm in width, and 5cm in height, save installation space without affecting its powerful functionality, providing convenience for the integration of industrial systems.

Weight: The net weight of the product is relatively light, approximately between 0.2kg and 0.3kg, which not only facilitates transportation and installation operations, but also does not bring excessive load pressure to the installation structure during equipment operation, helping to ensure the overall stability and reliability of the equipment.

Installation and maintenance

Installation method: The installation method is simple and easy to understand. The module is usually designed with standard installation holes, which can be fixed on the installation guide rail of the industrial control cabinet by screws. At the same time, its interface design adopts a standardized plug-in connection method. When conducting electrical connections, only the corresponding signal and power lines need to be correctly inserted into the interface according to the identification, without the need for complex wiring and wiring operations. For example, during the installation process, first fix the module on the guide rail, then insert the signal line of the sensor into the input interface, the control line of the actuator into the output interface, and finally connect the power cord to complete the basic installation.

Maintenance points: Regularly inspect the appearance of the module to check for physical damage, loose wiring, and other issues. Clean the dust and dirt on the surface of the module, maintain good heat dissipation conditions, and prevent the accumulation of dust from affecting module performance. During the operation of the system, pay attention to the status indicator lights on the module. Under normal circumstances, the indicator lights corresponding to the input and output channels will turn on and off according to the signal status. If the indicator lights display abnormally, it can be preliminarily judged that there is a fault in the channel. Regularly test the performance of the module, such as simulating input signals to check if the output is normal, to ensure that the module is always in good working condition. If a module malfunction is found, professional maintenance personnel should be contacted in a timely manner for inspection. Maintenance personnel can use professional tools to detect the internal circuit of the module, locate the fault point, and repair it to avoid industrial production interruption caused by module failure.
