EL9227 | Overcurrent protection terminal, 24 V DC, 2-channel, max. ∑ 10 A, adjustable, extended functionalities

The EL9227-xxxx electronic overcurrent protection terminal is a 24 V DC EtherCAT Terminal with an electronic protection function. The EL9227-xxxx is a two 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 10 A both via TwinCAT and via a mechanical button on the overcurrent protection terminal. In addition, there are further versions of the terminal with a fixed rated current. The protected output 1 can be fed out via a terminal contact or directly forwarded via the power contact of neighbouring terminals without wiring. The EL9227-xxxx 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.
