分布式输入/输出模块

分布式输入/输出模块可创建分布式控制系统，通过增加一些I/O信号实现技术目标和扩展PLC的功能。

这些模块也可以连接到我们的KPA EtherCAT 4CAN网关上。

另外：这些模块全部兼容以前的Selectron Systems AG生产的Selectron I/O-devices。

4通道模拟信号输入模块VSAI-4

(fully compatible with Selectron AIC 701 produced by Selectron Systems AG) with 4 isolated analog inputs serves to receive signals of either direct current or direct voltage or both from sensors and transform them into numeric code through each of the four inputs. Data exchange with Master PLC is executed through a serial communication channel based on CAN-interface (ISO 11898). Control and communication scheme is galvanically detached from the output signals scheme.
