E-T-A REX12D electronic circuit protector

The E-T-A REX12D electronic circuit protector is a protective element incorporating IO-Link that is suitable for mechanical engineering and process control. It combines system transparency and flexibility with a compact design.

The product is a double-channel electronic circuit protector which is mounted side by side with the EM12D-TIO supply module. Both modules feature push-in technology which requires no tools and saves wiring time. Current ratings 2 x 2, 2 x 4 and 2 x 6 A are available. Loads with a total rating up to 40 A can be protected if required by means of side-by-side rail-mounted circuit protectors, which can be connected with the help of a hinged connector arm. No bridges, jumpers or bus bars are required.

Status indication keeps users informed about the current state of each of the two channels of the device. Signalling shows connection of the load circuits and allows effective troubleshooting. The product offers a wealth of IO-Link communication options and thus enables service personnel to detect faults at an early stage and to react before the actual failure happens.

Faulty circuits will selectively be disconnected after approximately 3 s and after less than 10 ms in the event of a short circuit. Capacitive loads of up to 20,000 µF can be switched without problems. The internal failsafe element (blade fuse), which is adapted directly to the current rating of the circuit protector, allows easy adjustment to the cable cross-section.
