EL9221 | Overcurrent protection terminal, 24 V DC, 1-channel, max. 10 A, adjustable

The EL9221-xxxx electronic overcurrent protection terminal is a 24 V DC EtherCAT Terminal with an electronic protection function. The EL9221-xxxx is a single-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 can be fed out via a terminal contact or directly forwarded via the power contact of neighbouring terminals without wiring.
