Fail-safe Digital Expansion Module

Fault safety digital quantity module SM1226
The specifications for digital input and output (DI and DO) and fault safety signal modules are equivalent to standard modules. The functional safety of these modules has been certified in accordance with IEC 61508.
Its safety level reaches SIL 3 of IEC 62061 and PL e of ISO 13849.

The Failsafe Module of the S7-1200 is a safety function module designed for the S7-1200 PLC family, specifically designed to achieve a highly reliable and safe control system.

1. 1.Comply with international safety standards

Fail-safe modules comply with international safety standards such as SIL 3 (IEC 61508) and PLe (ISO 13849-1) and are suitable for applications with high safety requirements, such as mechanical safety and process control.

2. 2.Integrate security functions

The module has a variety of built-in Safety functions, such as Emergency Stop, Safety Door Monitoring, and Safe Speed Monitoring, which can effectively prevent the occurrence of dangerous situations.

3. 3.Simplify safety system design

By integrating safety features, you reduce the need for additional safety relays or standalone safety controllers, simplify system design and wiring, and reduce cost and complexity.

4. 4.Seamless integration with standard automation

The fail-safe module integrates seamlessly with the standard automation features of the S7-1200 and is programmed and configured using the same TIA Portal software without additional engineering tools.

5. 5.High reliability and diagnostic capability

The module has a powerful self-diagnosis function, which can monitor the system status in real time, quickly detect and report faults, ensure that the system can stop safely when there is an anomaly, and avoid accidents.

6. 6.Flexible scalability

Supports communication with other security devices (such as secure I/O, secure drives, etc.) via the PROFIsafe protocol, facilitating the extension of security functions to meet the needs of complex applications.

7. 7.Save space and cost

Safety functions are integrated into the PLC system, reducing the use of external safety elements and saving control cabinet space and installation costs.

8. 8.Efficient debugging and maintenance

Through TIA Portal software, you can easily debug, test, and maintain security programs, support online modification and monitoring, and improve engineering efficiency.

9. 9.Suitable for various application scenarios

Widely used in areas requiring high safety, such as packaging machinery, printing machinery, material handling, automobile manufacturing, etc., to ensure the safety of equipment and personnel.

10. 10.Fast response time

The fail-safe module has a fast response time and is able to trigger safety measures as soon as a hazardous situation is detected, minimizing risk.

The S7-1200 fail-safe module provides strong security for industrial automation systems by integrating safety features, simplifying system design and providing high reliability. It not only meets stringent international safety standards, but also reduces engineering cost and complexity, making it ideal for safety-critical applications.
