6ES7322-5FF00-0AB0 Siemens Simatic S7-300 Digital I/O Module

Product parameters

Module model: 6ES7322-5FF00-0AB0 (Siemens SM 322 Digital Output Module).

Output channel number: 32 channels, divided into 2 groups (16 channels in each group).

Output type: Relay output (non-polar, switchable AC/DC load).

Rated load voltage

Dc: 24VDC (typical value), range 19.2VDC-30VDC.

Communication: 230VAC (typical value), range 190VAC-264VAC.

Maximum load current: Maximum 2A per channel, maximum total current for each group (16 channels) of 8A, and maximum total current for modules of 10A.

Response time

Connection time: Maximum 10ms (resistive load).

Disconnection time: Maximum 5ms (resistive load).

Power supply

Internal power supply of the module: Provided by the S7-300 backplane bus (5VDC).

Load power supply: It needs to be provided externally separately (DC 24V or AC 230V, corresponding to the load type).

Operating temperature range: 0℃-60℃ (for operation), -25℃-70℃ (for storage).

Installation method: It needs to be installed in conjunction with the S7-300 series rail (such as the TS 35 rail), and connected to the CPU or interface module through the backplane connector.

Function

Signal conversion output: Receives digital control signals from the S7-300 CPU (such as "on/off" instructions), and switches them through relay contacts to drive the external actuator to act.

Group isolation protection: The 32 output channels are divided into 2 groups, each with independent electrical isolation, which can avoid interference from different load circuits and enhance system stability.

Overload and short circuit protection: Some models (including this model) integrate overload protection function. When the load current is too large or there is a short circuit, it can reduce the risk of module damage (external fuses are required for further enhanced protection).

Status indication: The front of the module is equipped with LED indicator lights for each channel, which can visually display the "powered on/off" status of the channel, facilitating on-site debugging and fault detection.

Application scenarios

Industrial equipment control: Drive actuators such as contactors, solenoid valves, indicator lights, and small motors, which are often used for start-stop control and process switching in machine tools and production lines.

Process automation: In industries such as chemical engineering, food processing, and water treatment, it controls the opening and closing of valves and the start and stop of pump sets to achieve the automated execution of production processes.

Buildings and infrastructure: It is used in building automation systems to control the on and off of equipment such as air conditioning fans, lighting circuits, and access control locks.

Automobile manufacturing and logistics: In the conveyor lines of automotive production lines and warehousing logistics, control the movements of conveyor belt motors and sorting mechanisms, and cooperate with sensors to achieve automated processes.
