EM12D-TIO-000-DC24V-40A

REX12D Electronic Circuit Protector Description 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 protection system comprising the REX12D circuit protector and the EM12D interface module. The system combines the well-proven quality of DC24V overcurrent protection with the communication options of the IO link 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 new generation of REX12D electronic overcurrent protection consists of the intelligent EM12-TIO supply module and the single or double channel REX12D-Telectronic circuit protector which allows modular side-by-side mounting. 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.

These two options are linked with AND. Switchon is only possible if switched on from both positions. If the circuit protector was switched off either by the control unit or by the momentary switch directly on the device, switch-on has to be effected also from the corresponding position. - Apply For switch-on the device has to be supplied operating voltage with operating voltage. The device restarts with the last stored condition. Reset function  A blocked load output (blocked by overload / short circuit) can be reset by the ON/OFF momentary switch or by the superordinate control unit.
