1. Specification

l Input points and channel grouping: Schneider 140DDI35300 has 32 input points, divided into 4 groups with each group containing 8 input channels. This method of grouping facilitates the management and differentiation of signals of different types or from different areas.

l Input voltage: Accepting 24 volts, with an operating voltage range of 5 to 30 VDC on "ON," the input voltage reading should be between -3 and 5 VDC when turned off.

l Input current: Schneider 140DDI35300 has a minimum input current of 2.0 mA and a maximum of 0.5 mA.

l Response time: The response time between the On and Off functions is 1 millisecond.. It helps to capture the changes of the input signal into the real-time bus variation in shorter times and that improves the real-time performance and control accuracy of the entire control system.

l Power consumption: Module power consumption is 1.7 watts, and each input under use swells it by 0.36 watts.

l Bus current: Schneider 140DDI35300 consumes a bus current of 330mA for communication with all other devices in the system.

l Addressing requirements: The requirement of two input words for addressing ensures efficient and accurate location when performing the identification for input signals in PLC programming.

l Input logic: The positive logic input and sink logic circuits

2. Features

l Online configuration and modification: Since Schneider 140DDI35300 has provided for an online configuration function that allows for flexible modification of the parameter settings for the module during system operation, it allows engineers to modify the inputs such as the filter time of the input signal, the turning on or off of the diagnostic function, etc. while the system is in operation, thus greatly improving the flexibility and maintainability of the system.

l Group isolation: Schneider 140DDI35300 uses the group isolation technique to prevent interference from input signals of various other groups and enhances the system's stability and reliability, particularly under complex environmental conditions that exist in a plant, thereby assuring accurate transmission and normal actuation of the system components.

l Accurate signal acquisition: The fast response time of 1 millisecond and stabilization of voltage input guarantee more accurate signal acquisitions and a faster response to input signals, thus improving control accuracy and product quality of production processes and reducing production losses that stem from image acquisition.

l Low power consumption design: The low power consumption of Schneider 140DDI35300 translates to better reliability. Less power consumption generates less heat and thus reduces the chance of damage to the module's internal components. In any continuous industrial automation system like chemical production, power generation, and other fields, smooth operation of the modules at all times is what guarantees safety and continuity of the production process. The low power consumption design of Schneider 140DDI35300 ensures long-term stable operation in harsh fields, reduces downtime caused by module failures, and increases the reliability of the entire production system.

3. Application

l Energy Generation: A major thermal power plant uses the Schneider 140DDI35300 module, which is part of the monitoring system for its generator sets. The module collects diverse sensor signals of generator sets. Among other things, it includes analog signals from oil temperature sensors, water temperature sensors, and pressure sensors, which control status signals from switching devices like circuit breakers and knife switches. The collected signals are transmitted to the control system, where the operator monitors the operating parameters and the status of the generator set in real time in the central control room.

l Intelligent Building: In a modern commercial office building, the Schneider 140DDI35300 module is used for its building automation system. Schneider 140DDI35300collects signals of the indoor and outdoor temperature sensors and humidity sensors in the air conditioning system, ventilation system fan operating condition, human body inferencing signal, and lighting system light intensity sensor signals, among others. By processing this information into controlled signals, the control system can achieve intelligent regulation and maintenance of the indoor temperature and humidity conditions, in a comfortable climate, by automatically regulating the cooling capacity and airflow rate of the AC in relation to indoor and outdoor temperature and by human activity control of switching on the lights and regulating their brightness according to light intensity and work done.

Automobile Manufacturing: In a large automobile manufacturing company, the Schneider 140DDI35300 module helps to build the automatic control system of its body workshop. A large number of robots are installed in the production line of this workshop for welding, handling, and other work, besides several conveyor lines and numerous fixtures. Manipulated via a Schneider 140DDI35300, the control system can see and hear all working status signals from each robot-the robot's ready signal, fault alarm signal, etc.-along with all the signals from conveyor line motor start and stop and arranging and loosening positions of the fixture.maximization of the production output.
