TRICONEX DI3301 Digital input module

Description

technical specifications
Number of input channels: Typically, there are 16 digital input channels that can be connected to 16 external devices simultaneously, enabling parallel acquisition of multiple digital signals.
Input signal types: Supports multiple types of digital signals, including TTL level signals (usually 0-5V), CMOS level signals (commonly 3.3V or 5V logic levels), and dry junction signals. This enables it to be compatible with various types of external devices, such as sensors, switches, relays, etc.
Signal detection characteristics: It can accurately detect the level status of input signals and has good anti-interference ability. For TTL and CMOS signals, it is possible to accurately distinguish between high and low levels, ensuring stable and accurate signal recognition even in complex industrial electromagnetic environments.
Response time: Fast response speed, usually in milliseconds, can quickly transmit changes in input signals to the control system, ensuring timely response to external events and meeting the real-time requirements of industrial process control.
Isolation feature: To prevent external interference from affecting the control system, each input channel is electrically isolated from the internal circuit of the system. The isolation voltage can usually reach several thousand volts, effectively improving the stability and reliability of the system and enhancing the anti-interference ability of the module in harsh industrial environments.
Power requirements: The working power supply is generally 24V DC, with a wide voltage tolerance range, such as 24V DC ± 20%, to adapt to different industrial power supply environments and ensure normal operation even in the presence of certain fluctuations in power supply voltage.
mechanical properties
Size: The module has a compact external size, making it easy to install in standard industrial control cabinets. The specific dimensions may vary depending on product design, but typically range from tens of millimeters to over a hundred millimeters in length, width, and height to accommodate different installation space requirements.
Weight: The weight is relatively light, usually around a few hundred grams, which will not cause excessive burden on the installation bracket and is convenient for installation and maintenance.
Installation method: Supports DIN rail installation, which is convenient, fast, easy to maintain and replace modules; At the same time, screw fixation installation can also be used according to actual needs, providing flexible installation options.
Diagnostic and maintenance functions
Channel status indication: Each input channel is equipped with a corresponding LED indicator light. By the on/off status of the indicator light, the input status of the channel (high or low level) and whether the channel is working properly can be intuitively understood, making it easy to quickly troubleshoot on-site faults.
Fault diagnosis function: The module has self diagnostic capability and can monitor its own working status in real time, including power failure, channel short circuit or open circuit and other fault situations. Once a fault is detected, the module will send the fault information to the control system through a specific communication protocol, and may trigger corresponding alarm outputs to remind maintenance personnel to handle it in a timely manner, which helps to quickly locate and solve problems and improve the maintainability of the system.
Online maintainability: Supports online plugging and unplugging functions. During system operation, modules can be safely removed or inserted for maintenance or replacement without affecting the normal operation of the entire control system, reducing system downtime and improving system availability.
