6ES7153-1AA03-0XB0 is an interface module produced by Siemens AG. Here is the relevant introduction:
1. Basic information:
Product type symbol: IM153-1 DP ST. The interface module in the distributed I/O (distributed input/output) system of Siemens S7 series PLC plays a role in connecting the central controller and distributed field devices in the automation control system.
2. Technical parameters:
Power supply voltage: The rated value is 24V DC, and the allowable voltage range is 20.4V to 28.8V. External safety devices are generally not required, but there are certain requirements for the stability of the power supply.
• Input current: The maximum current consumption is 350mA (at 24V DC), the typical turn-on current is 2.5A, and the current tolerance (i ² t) is 0.1A ² · s.
Output characteristics: The rated output voltage is 5V DC, and the maximum output current for the backplane bus (DC5V) is 1A, which can provide stable power support for other connected modules.
Address capacity: The address capacity of both the input and output terminals is 128 bytes, which facilitates data exchange and communication with the central controller.
3. Interface and Communication:
• Transmission mode: Adopting RS485 transmission mode, the transmission rate can reach up to 12Mbit/s, and supports automatic calculation of transmission rate. It can automatically adjust the transmission rate according to actual communication needs, ensuring the efficiency and stability of data transmission.
Physical interface: It is a 9-pin sub-d interface, which is a common industrial communication interface with good anti-interference and reliability.
Communication Protocol: Supports Profibus DP protocol (compliant with EN50170 standard), which is a widely used fieldbus protocol in the field of industrial automation, capable of high-speed and reliable data communication.
4. Other characteristics:
• Hardware Expansion: Each DP slave interface module can connect up to 8 S7-300 modules, with strong expansion capabilities to meet the needs of automation control systems of different scales.
Potential isolation: There is potential isolation inside the module, and the insulation test voltage is 500V, which can effectively prevent interference and fault transmission between different circuits, and improve the stability and reliability of the system.
• Protection level: The protection level is IP20, suitable for general industrial environments, which can prevent dust and foreign objects from entering, but does not have higher levels of protection such as waterproofing.
