6ES7321-1EL00-0AA0 Siemens Simatic S7-300 Digital I/O Module

Basic parameters

Input points: 32 channels, divided into 2 groups (16 channels in each group)

Rated input voltage: DC 24V

Signal "0" voltage range: -30 to +5V

The voltage range of signal "1" is 13 to 30 volts

Input current: Approximately 7mA at each input point (at 24V)

Input delay: Default 0.1ms (can be set to 10ms through software to suppress interference)

Power consumption: The typical value is approximately 5W

Backplane bus current: Maximum 150mA (5V DC)

Isolation: Electrical isolation between channel groups (each group is also isolated from the backplane bus), with an isolation voltage of 250V AC

Operating temperature: 0 to 60℃

Storage temperature: -40 to +70℃

Functional features

High-density input: 32-channel design, suitable for scenarios that require a large amount of digital signal collection, saving rack space.

Flexible anti-interference: Supports adjustable input delay, and the filtering time can be set according to the on-site environment to reduce the impact of electromagnetic interference.

Reliable isolation: Inter-group isolation design enhances the system's anti-interference ability and security, protecting the module and the back-end controller.

Easy to integrate: Compatible with the backplane bus of the S7-300 series PLC, no additional programming address is required, addresses are automatically allocated by slot, and hot plugging is supported (active bus module required).

Application scenarios

Industrial production line: Connect a large number of limit switches, buttons, proximity sensors, etc., to collect the operating status of equipment (such as the start and stop of conveyor belts, workpiece positioning signals, etc.).

Mechanical automation: Monitoring the status of multiple actuating components of equipment such as machine tools and packaging machinery (such as valve opening and closing, cylinder extension and retraction signals).

Process control assistance: In industries such as chemical engineering and food processing, it is used to collect digital signals from auxiliary equipment (such as the operating status of pumps and feedback on valve opening and closing).

Building automation: It can be integrated into the equipment monitoring system of large buildings to collect the switch signals of access control, lighting, air conditioning and other equipment.
