6ES7322-1BP50-0AA0 Siemens Simatic S7-300 Digital I/O Module

Product parameters

Output channel number: 8 channels, divided into 1 group (without group isolation).

Output type: Transistor output (NPN type, requires external DC power supply).

Rated load voltage: 24VDC (range: 19.2VDC to 30VDC).

Output current

The maximum current per channel is 0.5A (continuous current), and the peak current is 1A (continuous for 100ms).

The maximum total current of the module is 4A.

Switching frequency

Resistive load: Up to 100kHz (high-speed output, suitable for pulse control).

Inductive load: Maximum 2kHz.

Isolation method: Photoelectric isolation between the channel and the backplane bus (isolation voltage 2500V AC).

Power supply

Internal power supply: 5VDC is provided by the S7-300 backplane bus.

Load power supply: A separate 24VDC external supply is required.

Environmental parameters

Operating temperature: 0℃ to 60℃ Storage temperature: -25℃ to 70℃.

Protection grade: IP20 (To be installed in the control cabinet).

Function

High-speed digital output: Supports a maximum switching frequency of 100kHz, suitable for scenarios requiring rapid response (such as pulse width modulation (PWM), high-speed count triggering, etc.).

Transistor drive: The NPN type output is suitable for directly driving DC loads (such as small solenoid valves, servo driver control signals, indicator lights, etc.), with no mechanical contact wear and a longer service life.

Photoelectric isolation protection: Electrical isolation between the channel and the control system reduces the impact of external interference on the PLC and enhances system stability.

Status indication: Each channel is equipped with an LED indicator light to display the output status (on/off) in real time, facilitating quick fault diagnosis.

Application scenarios

Automated production line: Drive small solenoid valves, pneumatic valves, and servo motor control signals to achieve high-speed action switching (such as part positioning on assembly lines and conveyor belt speed regulation).

Precision equipment control: In printing machinery and packaging machines, it is used for high-speed counting pulse output and synchronous signal triggering to ensure the precise operation of the equipment.

Machine tools and robots: Auxiliary actions that control machine tools (such as coolant switches, tool clamping signals) or end effectors of robots (such as gripper opening and closing).

Testing and inspection equipment: Outputs high-frequency control signals, used for timing control in sensor calibration and product performance testing.
