TRICONEX 3501TN2 | digital input module

TRICONEX 3501TN2 is a digital input module

· Input voltage range: It usually supports multiple standard industrial voltages, such as 120VAC, 240VAC, 24VDC, etc., which can adapt to the power supply needs of 

different sensors and field devices.

· Number of input channels: There are generally 16 or 32 input channels of different specifications, which can simultaneously receive multiple digital signals to meet the 

signal acquisition needs of complex industrial sites.

· Input signal types: can receive various digital signal types such as dry contact signals, proximity switch signals, photoelectric switch signals, etc., and can be well compatible 

with various industrial sensors and switch devices.

· Isolation characteristics: The module has good electrical isolation between the internal input channels and internal circuits, and the isolation voltage can generally reach 

several thousand volts, effectively preventing external interference signals and overvoltage from affecting the system, and improving the stability and reliability of the system.

· Response time: It has a fast signal response time, usually in milliseconds, and can timely and accurately collect changes in the input signal, ensuring real-time monitoring 

of the on-site equipment status by the system.

· Diagnostic function: Equipped with comprehensive self diagnostic capabilities, it can monitor the working status of input channels, power supply voltage, module internal 

temperature, etc. in real time. Once a fault occurs, it can quickly issue an alarm signal and upload the fault information to the control system, making it convenient for maintenance personnel to locate and troubleshoot the fault in a timely manner.

· Signal acquisition in process control systems: In chemical, petroleum, power, metallurgical and other process control systems, digital signals from on-site sensors such as 

temperature switches, pressure switches, liquid level switches, etc. can be received. The control system monitors and controls key parameters in the production process 

based on these signals. When the parameters exceed the set range, corresponding control measures are taken in a timely manner, such as adjusting valve opening, changing 

motor speed, etc., to ensure the safety and stability of the production process.
