倍福BECKHOFF EL1889

The EL1889 digital input terminal acquires the binary 24 V control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The EtherCAT Terminal has 16 channels, whose signal states are indicated by LEDs. The power contacts are connected through. With the EL1889, the reference ground for all inputs is the 24 V power contact.

Special features:

ground switching

no bouncing due to mechanical switches thanks to 3 ms input filter

tool-free connection by direct plug-in technique for solid wire conductors

space-saving use in the control cabinet

direct connection of multi-channel sensors in 1-wire connection technology in the smallest space

EL1889数字输入终端从过程级获取二进制24 V控制信号，并以电气隔离形式将其传输至更高级别的自动化单元。EtherCAT终端有16个信道，其信号状态由LED指示。电源触点通过连接。对于EL1889，所有输入的参考接地是24 V电源触点。

特殊功能：

接地开关

由于3ms输入滤波器，机械开关不会产生跳动

实心导线直接插入式无工具连接

控制柜节省空间

在最小空间内采用单线连接技术实现多通道传感器的直接连接
