安全保护功能在许多自动化控制领域都是必须的. 安全系统包括生产线上的紧急停止开关, 安全输入信号比如安全光幕和安全门互锁开关，这些都可以用于自动的停止机器上潜在的危险动作。安全系统的构建需要考虑的是安全等级的高低。早期的安全网络仅仅依靠接线方式实现安全,在相关的地方标准中有定义一些冗余接线或特殊保护方法。
一个网络中的标准安全组件；连接机械接触，如安全接触元件；用于连接倍加福生产的电感式控制安全传感器（SN传感器）；安全模块有两个安全输入口；安全模块有两个安全输入口和两个安全输出口，允许输入口与输出口之间通过参数位逻辑连接；安全控制柜和总线模块。
产品特点：● Several safe output modules grouped to form a release circuit
● 2 galvanically isolated contact banks
● 4 conventional inputs, 1 of which can be switched as a protective feedback circuit
● SIL3 (IEC 61508)
● Addressing jack
● Occupies one complete address for the safe output and one A/B address for the 4 inputs
