Type REX22D-T
Description
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.

Improve Plant Production by Addressing 24VDC Switch-Mode Power Supply Issues
For most industries, the accepted norm for unplanned downtime is 5% of operating time, which represents a direct, significant loss of revenue and therefore profit. But have you ever stopped to consider the true cost of downtime? Read the latest white paper from E-T-A to see how the integration of electronic circuit control technology can reduce the downtime of your 24VDC system designs.
Utilizing Class I Div. 2 Circuit Breakers in Liquid Natural Gas Applications
An increase in the demand for energy worldwide has driven the search for alternative primary sources of energy, even to the most remote locations of the globe. Natural gas is considered the cleanest burning fossil fuel with minimal environmental impact. This white paper shares a real world example of how the integration of electronic circuit protection eliminates the need for widely used NEMA 7 enclosures.
