EL1004-0020 EtherCAT Terminal
The EL1004-0020 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 four channels that indicate their signal state via light emitting diodes.
Special features:
Input specification type 1/3.
No bouncing due to mechanical switches thanks to 3 ms input filter.
Direct connection of four 2-wire sensors via additional +24 V connection points.
Electrical isolation of 2500 V (functional isolation) between test voltage on the E-bus and field voltage.
