TRICONEX DI2301 7400208-020 Digital input module

Description

technical specifications
Number of input channels: Typically, there are 16 independent digital input channels that can simultaneously connect digital output signals from 16 external devices.
Input signal type: Supports multiple standard digital signals, such as TTL level signals (usually 0-5V), CMOS level signals (usually 3.3V or 5V logic level according to different CMOS processes), and dry junction signals.
Signal detection accuracy: It can accurately detect the level status of input signals. For TTL and CMOS signals, it can accurately distinguish high and low levels, with strong anti-interference ability, ensuring stable operation even in complex industrial electromagnetic environments.
Response time: The response time of the module is extremely short, usually in milliseconds, which can quickly transmit changes in the input signal to the control system, ensuring timely response of the system to external events.
Isolation feature: In order to prevent external interference from affecting the control system, each input channel is electrically isolated from the internal circuit of the system, and the isolation voltage can usually reach several thousand volts, effectively improving the stability and reliability of the system.
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 environments.
mechanical properties
Size: The external dimensions of the module are compact, making it easy to install in standard industrial control cabinets. Typically, its length, width, and height range from tens of millimeters to over a hundred millimeters, and specific dimensions may vary depending on product design.
Weight: It is relatively light, usually around a few hundred grams, and will not cause excessive burden on the installation bracket.
Installation method: Supports DIN rail installation, which is convenient, fast, easy to maintain and replace. It can also be fixed with screws according to actual needs.
Diagnostic and maintenance functions
Channel status indication: Each input channel is equipped with corresponding LED indicator lights, and the on/off status of the indicator lights can intuitively understand the input status (high or low) of the channel and whether the channel is working properly.
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.
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, greatly improving the maintainability and availability of the system.
