6ES7321-1BL00-0AA0 Siemens Simatic S7-300 Digital I/O Module

Product parameters

Input points: 32 digital input points, divided into 4 groups (8 points in each group).

Input voltage: DC 24V (allowable range: DC 19.2V-30V).

Input current: Rated current of 7mA per point (at 24V).

Response time: Standard mode (typical value 6.4ms), fast mode (typical value 0.12ms), which can be selected through hardware dip code.

Isolation method: Channel group isolation (8 points in each group are electrically isolated from the backplane bus), isolation voltage 500V AC (1 minute).

Input type: Compatible with NPN/PNP sensors (pole-independent, flexible wiring).

Status indication: Each input point is equipped with a green LED indicator light, which lights up when the signal is connected, facilitating intuitive diagnosis.

Power supply: Power is drawn through the S7-300 backplane bus, without the need for an external independent power source.

Environmental adaptability: Operating temperature 0°C-60°C, storage temperature -40 °C-70°C, protection grade IP20 (needs to be installed in a control cabinet).

Function

Multi-channel signal acquisition: The 32-point input design can centrally collect a large number of external digital signals (such as the on-off status of multiple switches and sensors), reducing the space occupied by the module and lowering the system cost.

High-speed response capability: The response time in the fast mode is as low as 0.12ms, capable of capturing rapidly changing signals (such as state detection before high-frequency counting in a pipeline).

Anti-interference and protection: The group isolation design weakens on-site electrical interference and ensures the stable operation of the PLC system. A wide voltage range is adapted to the fluctuations of industrial power supplies.

Convenient debugging: LED indicator lights provide real-time feedback on the signal status of each point, enabling quick location of wiring or equipment faults and simplifying the on-site debugging process.

Application scenarios

Large-scale production lines: Centralized collection of limit switches and photoelectric sensor signals from multiple conveyor belts (such as workstation status monitoring on automotive assembly lines).

Equipment cluster control: In the machine tool workshop and packaging workshop, monitor the emergency stop button and safety door switch status of multiple devices to achieve centralized safety monitoring.

Infrastructure monitoring: It is used in scenarios such as building automation (such as access control switches for multiple rooms and fire alarm buttons), water treatment plants (feedback signals for the switch of multiple valves), etc.

Logistics and warehousing system: Collect shelf position sensors, conveyor start and stop signals, sorter arrival signals, etc., to support the logical control of warehousing automation.
