Here is the parameter information about the inputs and outputs of the OMRON NX - SL3()()() I/O System module:
Input Type: Digital input.
Number of Input Channels: Usually, there are 8 or 16 input channels, depending on the specific model.
Input Voltage: It typically accepts voltages in the range of 24 VDC ± 10%, which means it can work properly with input voltages between 21.6 VDC and 26.4 VDC.
Input Current: Each input channel has a relatively low current consumption, usually in the range of a few milliamperes.
Input Logic: It can be configured to support both sinking and sourcing input signals. For sinking inputs, the signal is connected to the negative terminal of the power supply, while for sourcing inputs, it is connected to the positive terminal.
Response Time: The input response time is fast, usually within a few microseconds, enabling the module to quickly detect changes in input signals and meet the requirements of real - time monitoring.
Noise Immunity: The module is designed to have high noise immunity, allowing it to operate reliably in industrial environments with significant electrical noise and interference. It can withstand a certain level of noise without affecting the accuracy of input signal detection.
Output Type: Digital output.
Number of Output Channels: Similar to the input channels, the number of output channels depends on the specific model, which may be 8 or 16.
Output Voltage: The nominal output voltage is generally 24 VDC, but it can also be designed to work with other voltages such as 12 VDC or 48 VDC according to different application requirements.
Output Current Capacity: Each output channel can typically source or sink a certain amount of current. For example, it may be able to handle a maximum output current of 0.5 A or 1 A per channel, depending on the module's design and rating.
Output Logic: The output logic can be configured as either sinking or sourcing according to the needs of the connected devices. Sinking outputs connect the load to the positive supply, while sourcing outputs connect the load to the negative supply.
Response Time: The output response time is relatively fast, usually in the order of milliseconds, which is beneficial for the quick activation and de - activation of connected loads and meets the requirements of precise control in real - time applications.
Protection Features: The outputs are usually equipped with protection mechanisms such as over - current protection, short - circuit protection, and reverse - polarity protection to protect the module and the connected equipment from damage in case of abnormal operating conditions.
NX-SL3300: It has 32 safety master connections, a maximum of 256 safety I/O points, a program capacity of 512 KB, and its I/O refreshing method is free-run refreshing.
NX-SL3500: It has 128 safety master connections, a maximum of 1024 safety I/O points, a program capacity of 2048 KB, and its I/O refreshing method is also free-run refreshing.
