6ES7322-1FL00-0AA0 Siemens Simatic S7-300 Digital I/O Module

Product parameters

Output channels: 8 independent digital output channels, transistor type (NPN)

Load voltage: 24V DC (Only supports DC load, not compatible with AC load)

Load current: Maximum 0.5A for A single channel, maximum total current of 2A for every group of 4 channels, and maximum total current of 4A for the entire module

Switching frequency: High-speed response, with a maximum switching frequency of 200 Hz per channel (resistive load), meeting the high-frequency start-stop requirements

Electrical isolation: Photoelectric coupling isolation between the channel and the backplane bus. Four channels are grouped together for isolation, which has strong anti-interference ability

Power loss: Typical power consumption is approximately 3.5W, and no-load power consumption is about 1.8W

Protection grade: The front-end protection grade of the module is IP20 (standard industrial control cabinet installation protection)

Working environment: Working temperature 0℃ to 60℃, storage temperature -25 ℃ to 70℃. Relative humidity 5% to 95% (no condensation)

Mechanical features: Compatible with S7-300 standard rail installation, module width approximately 25mm, supports hot plugging (system configuration support required)

Function

High-speed digital output: Transistor output architecture, with a switching frequency of up to 200 Hz, far exceeding that of ordinary relay modules, enabling precise control of high-frequency operating equipment

Group isolation and anti-interference: The group photoelectric isolation design effectively blocks the electromagnetic interference from the external load side, ensuring the stable operation of the S7-300 CPU and the backplane bus

Load protection adaptation: Supports 24V DC standard industrial load, single-channel 0.5A output capability, can directly drive small solenoid valves, sensors, indicator lights, etc., without additional relay amplification (for medium and small power scenarios)

Seamless system integration: Real-time communication with the CPU via the S7-300 backplane bus, supports STEP 7 software configuration, is compatible with industrial buses such as PROFIBUS-DP and PROFINET, and can be integrated into distributed control systems

Hot-swappable maintenance: Supports online module replacement (subject to system power redundancy and configuration Settings), reducing equipment downtime for maintenance

Application scenarios

Automated production lines: Control the start and stop of high-speed conveyor belts, the action switching of sorting machines, and the high-frequency reversing of small pneumatic/hydraulic solenoid valves (such as electronic component assembly lines, food packaging lines)

Intelligent manufacturing equipment: Auxiliary action control of CNC machine tools (such as fixture clamping/releasing, coolant valve opening and closing), precise drive of robot end effectors (such as small suction cups, grippers)

In the electronics manufacturing industry: workstation switching for PCB board soldering equipment, probe extension and retraction control for component testing equipment, light source switching and cycle time control for LED production lines

Logistics and warehousing equipment: Start and stop control of small conveyor roller tracks, action of guiding mechanisms in sorting systems, drive of location detection trigger devices for storage shelves

Small-scale process control: Valve opening and closing of laboratory equipment, pump body start and stop of small-scale water treatment equipment, fan coil unit control in building automation (24 V DC load scenario)
