Bulletin 1797 FLEX Ex? 本安 (IS) I/O 为危险应用项目带来了灵活性。将 FLEX Ex I/O 与安装在危险区域中的 FLEX Ex 通信模块结合使用，可在源头收集数据，并以最少的接线将数据传输到安全区域。高级诊断功能提供实时状态，以便更加方便地进行故障处理。

 特性

每个模块最多有 16 个 I/O 点 

每个组件可连接多达 8 个模块，最多有 128 个 I/O 

通过带电插拔 (RIUP)，可在系统运行期间在危险区域中更换模块和进行电缆连接 

每个 I/O 模块都需要一个端子座，上面有用于 I/O 接线的连接点。

Bulletin 1797 FLEX Ex? Intrinsically safe (IS) I/O brings flexibility to hazardous application projects. By combining FLEX Ex I/O with FLEX Ex communication modules installed in hazardous areas, data can be collected at the source and transmitted to a safe area with minimal wiring. Advanced diagnostic features provide real-time status for more convenient fault handling.

characteristic

Each module can have up to 16 I/O points

Each component can connect up to 8 modules with a maximum of 128 I/Os

By using RIUP, modules can be replaced and cables can be connected in hazardous areas during system operation

Each I/O module requires a terminal block with connection points for I/O wiring.
