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數(shù)字輸入終端從過程級獲取二進制24 V控制信號，并以電氣隔離形式將其傳輸至更高級別的自動化單元。EtherCAT終端有16個信道，其信號狀態(tài)由LED指示。電源觸點通過連接。對于EL1889，所有輸入的參考接地是24 V電源觸點。

特殊功能：

接地開關

由于3ms輸入濾波器，機械開關不會產(chǎn)生跳動

實心導線直接插入式無工具連接

控制柜節(jié)省空間

在最小空間內(nèi)采用單線連接技術實現(xiàn)多通道傳感器的直接連接
