The EL9227-4400 electronic overcurrent protection terminal is a 24 V DC EtherCAT Terminal with an electronic protection function including NEC Class 2 approval according to UL1310. The EL9227-4400 is a 2-channel device and switches 24 V DC overcurrents off reliably. The rated current can be adjusted in 1 A steps up to a maximum of 4 A both via TwinCAT and via a mechanical button on the overcurrent protection terminal. The protected output 1 can be fed out via a terminal contact or directly forwarded via the power contact of neighboring terminals without wiring.

 

The EL9227-4400 is ideally suited for plant monitoring, since numerous process data are available and status data can be both displayed and stored. In addition, there are some extended optional settings, such as e.g. characteristic curve selection, undervoltage/preliminary warning level, last state, etc. By using the EL9227-4400, NEC Class 2 circuits (< 100 VA) can be implemented with standard power supplies.
