Specification parameters

（1） Number of channels

Both modules are equipped with 16 digital output channels, which can simultaneously control 16 different devices or actuators, meeting the demand for digital output points in small and medium-sized industrial automation projects. Both simple production line control and complex equipment logic control can provide sufficient output channel resources.

（2） Electrical parameters

Voltage Range: XO16N1-B20 and XO16N1-C3.0 typically support a working voltage of DC 24V, adapting to common industrial DC power standards and ensuring power compatibility with most industrial control systems.

Output current: Each channel can provide a certain driving current, for example, the output current of a single channel can reach 0.5A or higher, which can directly drive some small relays, indicator lights and other loads. The specific output current capability may vary among different versions or models.

Isolation feature: It has electrical isolation function, effectively preventing external electrical interference from affecting the internal circuit of the module, and improving the stability and reliability of the module's operation. At the same time, it can also prevent module failures from causing damage to other devices, ensuring the safe operation of the entire control system.

（3） Physical characteristics

Size and Installation: Adopting a compact design with a small volume, it is easy to install in various control cabinets or equipment chassis. The standard DIN rail installation method is usually supported. Simply insert the module into the rail and fix it in place to complete the installation. The operation is simple and fast, saving installation space and time.

Environmental adaptability: It can work stably within a certain temperature and humidity range, with a working temperature range of -25 ℃ to+60 ℃ and a relative humidity range of 5% -95% (without condensation). This wide range of environmental adaptability makes it suitable for various industrial site environments, including harsh workplaces such as high temperature and humidity.

Core functions

（1） Digital Logic Processing

The module is equipped with rich logical operation functions, which can perform basic logical operations such as AND, OR, NOR, XOR on input digital signals, as well as complex temporal logic processing. Users can customize the logic program of modules through programming software according to their actual industrial control needs, achieving diversified control logic and meeting the requirements of different production processes.

（2） Stable signal output

Capable of outputting stable and reliable digital signals to ensure accurate control of actuators. Whether it is continuously outputting high-level or low-level signals, or switching signals according to specific timing, it can ensure the stability and accuracy of the signal, avoid equipment misoperation caused by signal fluctuations, and ensure the stable operation of industrial production processes.

（3） Status monitoring and feedback

Equipped with status monitoring function, it can monitor the working status of each output channel in real time and display it intuitively through LED indicator lights. When a channel malfunctions or is abnormal, the corresponding LED indicator light will light up or flash in a specific way, making it convenient for operators to quickly locate the fault point. Meanwhile, some models of modules also support feedback of channel status information to the control system, facilitating remote monitoring and fault diagnosis.

（4） Communication function

Supports multiple communication protocols, such as Modbus RTU, Profibus DP, etc., and can communicate with main controllers such as PLC and DCS (Distributed Control System). Through communication connections, the main controller can read the working status of modules in real time, modify logical program parameters, achieve remote control and centralized management of modules, and improve the intelligence and management efficiency of industrial automation systems.

Working principle

When the digital logic module is connected to the industrial automation control system, it first receives digital signals from the main controller or other devices. These signals enter the internal circuit through the input interface of the module, undergo signal conditioning and isolation processing, and are transmitted to the logic operation unit. The logical operation unit performs corresponding logical operation processing on the input signal according to the logic program pre programmed by the user.

The processed result is transmitted to the output driving unit, which controls the corresponding output channel based on the operation result to output a high-level or low-level signal, thereby driving the action of the external actuator. At the same time, the status monitoring circuit monitors the working status of each output channel in real time and feeds back the status information to the display unit (LED indicator light) and communication unit, so that operators can view and control the system for remote monitoring.

Key advantages

（1） High reliability

By using high-quality electronic components and advanced manufacturing processes, and undergoing strict quality inspection and testing, the module ensures long-term stable operation in complex industrial environments. The electrical isolation design and improved fault protection mechanism effectively enhance the anti-interference ability and reliability of the module, reduce equipment failure rate, and decrease maintenance costs and downtime.

（2） Strong flexibility

Users can flexibly customize the logic program of modules according to different industrial control needs, achieving diversified control functions. Rich communication protocol support enables integration with multiple main controllers and devices, facilitating system expansion and upgrading, and meeting the personalized needs of different industrial automation projects.

（3） Easy to use

The standard DIN rail installation method and intuitive LED indicator design make module installation, debugging, and maintenance easier. At the same time, the supporting programming software has a user-friendly interface, rich functions, and sample programs, which even experienced engineers can quickly get started and shorten the project development cycle.

（4） High cost-effectiveness

While providing high performance and reliability, with a reasonable price positioning, it can provide cost-effective digital logic control solutions for enterprises, helping them reduce the procurement cost of automation equipment while ensuring production efficiency and product quality.

Precautions

（1） Installation and wiring

When installing modules, it is important to ensure that the installation environment meets the requirements for module use and avoid installing in harsh environments such as high temperature, humidity, and strong electromagnetic interference. During the wiring process, strictly follow the wiring diagram in the product manual to ensure the correct connection of power and signal lines, and avoid module damage or system failure caused by wiring errors.

（2） Programming and Configuration

When using programming software to write logic programs and configure parameters for modules, it is important to carefully verify the accuracy and completeness of the program. Before downloading the program, it is best to conduct a simulation test to ensure that the program can achieve the expected control functions. Meanwhile, pay attention to saving the programming files for future modifications and maintenance.

（3） Operation and maintenance

During the operation of the module, regularly check the status of the LED indicator lights and promptly detect any abnormal situations. According to the recommendations in the product manual, perform regular maintenance on the module, such as cleaning the surface dust and checking for loose electrical connections. When a module malfunctions, do not disassemble it randomly. First, disconnect the power supply, refer to the fault diagnosis manual for troubleshooting and handling, and contact professional technicians for repair if necessary.
