Type REX22D-T

The compact and flexible REX system is an all-in-one solution offering comprehensive DC 24 V protection and distribution options for machines and process control. It helps optimise the functionality and number of components.
The REX22D-T electronic circuit protector selectively protects all DC 24 V load circuits up to 20 A and limits the output current linearly during switch on or before tripping. The limitation cuts down the current rating in the event of a short circuit. This enables an effective and predictable protection even for switch mode power supplies with low power reserves.

Thus, the electronic characteristic curve additionally provides solutions for the protection of drive engineering, control technology for frequency converters, multiphase motors and sensitive relay contacts.
The only 12.5 mm wide modules, which can be modularly mounted side by side, are completely designed in push-in technology incl. pusher. Tool-free, time-saving and maintenance-free wiring are guaranteed.

Save costs!

• Transparency and flexibility through adjustable current ratings via slides
• Reduced downtimes through calculable limited max. current
• Increased availability by avoiding nuisance tripping

All REX22D-T modules can be operated in the BASE and also in the COM mode. While the BASE mode provides an error message via the auxiliary contact in the supply module, the COM mode offers a variety of diagnosis, control and parametrisation options by means of different communication modules. All devices automatically recognise the respective operating mode.
