模块化系统中选型举例

模块化系统

3SF11.4 和 3SF12.4 系列行程开关具有模块化结构设计，由不同形式的基本开关和按钮头（需单独订购）组成。得益于开关的模块化设计，终用户可以从为数众多的型号中选择适合自己应用的正确解决方案，并在很短时间内自行安装。

设计

3SF1 开关有 4 种不同按钮盒规格可供选择：

• 根据 EN 50047，塑料按钮盒，31 mm 宽，带 M12 设备接头

• 根据 EN 50041，塑料按钮盒，40 mm 宽，带 M12 设备接头

• 塑料按钮盒，50 mm 宽，带 M12 设备接头和 M12 接口

• 金属按钮盒，56 mm 宽，带 M12 设备接头和 M12 接口

显示

该开关系列配有带三个 LED 的状态显示屏：

• LED 1（黄色）：F‑IN1

• LED 2（黄色）：F‑IN2

• LED 3（绿/红）：AS-i/FAULT

连接

到 AS-Interface 的连接是通过一个连接到黄色 AS-Interface 总线电缆的 4 针 M12 接口（塑料型）完成的。

宽外壳（50 或 56 mm）还具有用于连接第二个行程开关的 M12 接口。如此，可实现安全等级 SIL 3 ( IEC 62061/IEC 61508) 或 PL e ( ISO 13849‑1)。

优势

The 3SF1 safety switches offer:

• ASIsafe electronics integrated in the enclosure, with low power consumption < 60 mA

• An extensive range of actuators

• Status display with three LEDs

• Can be integrated easily via TIA Portal

应用

With the standard position switches, mechanical positions of moving machine parts are converted into electrical signals. Through their modular and uniform design and large number of variants, the devices can comply with practically all re in industry.

Devices are available with enclosure versions to suit the particular ambient conditions. Different control tasks can be performed with the contact blocks best suited for the particular purpose. And many different actuator variants are available to match the mechanical configuration of the moving machine parts. Dimensions, fixing points and characteristics are largely according to the EN 50041 or EN 50047 standards.

The devices are suitable for use in any climate.

Standards

The switches comply with IEC 60947‑1 (Low-Voltage Controlgear, General) and IEC 60947‑5‑1 (Electromechanical Control Circuit Devices).

The mechanical design of the switch corresponds to the re of the fail-safe principle according to ISO 14119.

Approvals

AS-Interface according to IEC 62026‑2

The 3SF1 position switches are approved according to UL 508, UL 50 and UL 746-C.

Safety circuits

Standard IEC 60947‑5‑1 requires positive opening of the NC contacts. In other words, for the purposes of personal safety, the assured opening of NC contacts is expressly stipulated for the electrical e of machines in all safety circuits and marked in accordance with the standard IEC 60947‑5‑1 with the symbol (→).

With a 3SF1 safety switch with (→), SIL 2 according to IEC 2061/IEC 61508 or PL c according to ISO 13849‑1 can be attained if the corresponding fail-safe evaluation units are selected from the ASIsafe program and correctly installed.

If a second 3SF1 safety switch with (→) is used, SIL 3/PL e can be attained.

Evaluation of safety functions

Safety Evaluation in the TIA Selection Tool

The safety evaluation for the IEC 62061 and ISO 13849-1 standards is performed and easily, directly in the TIA Selection Tool. In addition to the fast and safe calculation of machine safety functions – from the definition of the system structure to the selection of components – this enables shared data management during all project phases. Take the next step in the digital design of machinery and e with Safety Evaluation in the TIA Selection Tool.

In addition, the functionalities of the proven Safety Evaluation Tool are still available. It determines the achieved safety integrity (SIL/PL) step-by-step. You receive the results as a standards-compliant report that can be integrated in the documentation as proof of safety.
