Number of Input Channels: It has 32 digital input channels, which can collect 32 external digital signals at the same time, meeting the demand for the number of digital signal acquisition in small and medium-sized industrial control systems, and can be flexibly applied to control scenarios of different scales.
Input Signal Type: It supports DC input signals, is compatible with the output signals of NPN or PNP type sensors, has strong compatibility, and can be connected with various types of external digital devices.
Response Time: The response time of the input signal is short, usually within 1ms, which can quickly capture the state changes of external devices, ensure the real-time response of the control system to on-site signals, and is suitable for industrial control occasions with high requirements for signal real-time performance.
(2) Interface Characteristics
Input Interface: Equipped with 32 independent digital input interfaces, using screw terminal connection mode, the wiring is firm and reliable, and easy to install and maintain. Each input interface has a clear identification corresponding to the corresponding channel number, which is convenient for technicians to perform wiring operations. The interface has good electrical isolation performance, which can effectively prevent external voltage fluctuations or interference from affecting the internal circuit of the module, ensuring the stability of signal acquisition.
Backplane Interface: It communicates with the PLC processor through the rack backplane interface of the Series 90-30 PLC, and transmits the collected digital signals to the PLC processor. The backplane interface adopts a reliable electrical connection design to ensure the timeliness and accuracy of signal transmission, making the module and the PLC system form an organic whole to collaboratively complete signal acquisition and control tasks.

(3) Environmental Adaptability
Operating Temperature: The operating temperature range of the module is 0°C to 60°C, which can adapt to the temperature environment of most industrial production workshops. In high-temperature environments, stable signal acquisition performance can be maintained through a reasonable heat dissipation structure; in low-temperature environments, the internal circuit can also start and run normally, ensuring the continuity of signal acquisition and the stable progress of industrial production.
Storage Temperature: In the storage state, it can withstand extreme temperatures from -40°C to 85°C, which can meet the temperature requirements of the product in transportation, storage and other links, ensuring that the module can still be used normally after long-term storage without performance degradation or damage due to temperature issues.
Anti-Electromagnetic Interference: It meets industrial-grade electromagnetic compatibility standards and has strong anti-electromagnetic interference capabilities. Through internal electromagnetic shielding and filtering circuits, it can effectively resist electromagnetic interference generated by equipment such as motors, frequency converters and electric welders in industrial sites, prevent input signals from being misjudged due to interference, and ensure the reliability of digital signal acquisition.

III. Functional Characteristics
The core function of the IC693MDL940 module is to realize high-precision acquisition of external digital signals. It can accurately identify the switch state of external devices, such as the pressing and releasing of buttons, the triggering and resetting of limit switches, the presence or absence of detection by sensors, etc., and convert these states into digital signals (0 or 1) recognizable by the PLC processor. Each input channel of the module works independently, can collect multiple signals at the same time, and has high acquisition accuracy. The accuracy of signal acquisition will not be affected by the large number of channels, providing reliable original data for the logical control of the PLC system.
(2) Powerful Anti-Interference Function
In view of the complex electromagnetic environment in industrial sites, the module adopts multiple anti-interference measures and has a powerful anti-interference function. The internal filtering circuit can effectively filter out high-frequency interference and noise in the input signal, ensuring that the collected signal is pure and stable; the electrical isolation design isolates the external input signal from the internal circuit of the module, preventing external interference from being transmitted into the module through the signal line and affecting the normal work of other circuits. Even in industrial environments with strong electromagnetic interference, the module can stably and reliably collect digital signals, avoiding misoperation of the control system caused by interference.

(3) Diagnosis and Status Indication Function
The module is equipped with perfect diagnosis function and status indication function, which is convenient for technicians to monitor the operation status of the module and troubleshoot faults. The module is equipped with a status indicator light for each input channel. When a channel collects a signal, the corresponding indicator light is on, so that technicians can intuitively understand the working status of each channel. At the same time, the module can also diagnose its own operating status, such as power failure, internal circuit failure, etc. When a fault occurs, the corresponding fault indicator light will be on, and the fault information will be transmitted to the PLC processor through the backplane interface, facilitating the system to alarm and handle in time.
