· 极为经济，无参数设置或诊断功能

Area of application

数字量输入模块可记录设备中的 24 V DC 或 230 V AC 信号，并将它们传送到控制器。可以连接开关以及 2 线制、3 线制或 4 线制接近开关。

35 mm 宽的输入模块具有可设定的参数和诊断功能，因此可根据相应过程要求进行灵活调整。

25 mm 宽的低成本模块没有可设定的参数或诊断功能，可极为方便地集成到工程系统中。建议将它们在只需要很少输入通道的位置使用，或在必须在十分有限的空间内部署大量通道的情况下使用。

根据需要，可在一个站中并排使用两种模块。由于具有统一特性并采用共同的系统附件，处理十分方便。
