B&R 7DI140.70 Digital input module

B&R 7DI140.70 is a digital input module in B&R 2003 system. Here is its detailed introduction:

Functional characteristics

Input channel: It has 10 24VDC input channels and adopts leakage input mode. This input mode can reliably receive digital signals from external devices, such as signals from switches, sensors, etc.

Special function input: 2 of the input channels can be used for event counter operation or direction-related position evaluation, which can meet some application scenarios that require accurate counting or position detection. The input frequency can reach 50kHz, which can accurately capture high-speed changing signals. The other 4 inputs can be used as high-speed inputs for gate signals, frequency measurement and other functions, but these functions are only available when used with the CPU interface.

Other functions: The module also has TPU (time processor) function and voltage monitoring function. The TPU function can be used to achieve high-precision time control and signal processing, and the voltage monitoring function can monitor the state of the input voltage in real time to ensure that the module operates within the normal operating voltage range and improve the stability and reliability of the system.

Physical characteristics

Installation method: It is a screw-in module, which is easy and quick to install. It can be firmly installed on the standard DIN rail, saving space and facilitating maintenance.

Dimensions and weight: The dimensions are about 2.5cm×8.4cm×5.1cm, and the weight is about 0.2kg. It is small in size and light in weight, suitable for various industrial control occasions with limited space.

Application scenarios

Industrial automation production line: In the automated production lines of industries such as automobile manufacturing and electronic equipment production, it can be used to collect switch signals, sensor signals, etc., such as detecting the position of products, the operating status of equipment, etc., to provide accurate input information for PLC to achieve precise control of the production line.

Mechanical equipment control: For various mechanical equipment, such as machine tools, packaging machines, printing machines, etc., it can be used to receive signals such as limit switches, buttons, proximity sensors, etc. on the equipment to realize the logical control and safety protection functions of the equipment.

Process control system: In process industries such as chemical and pharmaceutical industries, it can be used to monitor various switch states, such as the opening and closing state of valves, the operating state of pumps, etc., to provide basic digital input signals for process control, and ensure the safety and stable operation of the production process.
