Type: REX12D-T


80 mm

The compact and flexible all-in-one solution REX consists of several perfectly matched components. It comprises the EM12D-T / EM12-T supply module for the plus and minus potential via a single or double channel REX12D-T electronic circuit protector which can be mounted side by side in any number and the PM12-T potential extension module for plus and minus multiplication.

The requirements regarding modern machinery and equipment are constantly growing. System transparency, remote maintenance and remote access are getting more and more important in international competition. Early notification in the event of any disturbances and a fast response to current problems will increase system availability, save costs and improve the overall stability of the production process.

E-T-A provides the ideal solution for machine and panel builders with the intelligent REX12D protection system and the EM12D interface module. The system combines the well-proven quality of DC24V overcurrent protection with the communication options of the IO link and Modbus-RTU system. It allows complete transparency of the DC24V power supply and provides all necessary information for a reliable production process in this plant sector.

The modules with a width of only 12.5 mm feature push-in technology including press release buttons and allow time-saving and maintenance-free wiring without tools.

And what is more: no additional accessories are required when connecting the individual components electrically and mechanically. This helps save time and money!
