3 General description
Requirements in plant engineering and construction and in building automation are growing and growing. In
the context of increasing efficiency and reducing costs, the transparency of systems, remote maintenance
and remote access are getting more and more important. 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 capabilities to superordinate
bus systems. It allows complete transparency of the DC24V power supply and provides all necessary
information for a reliable production process in this plant sector. Part of the information is the permanent
transmission of status indication regarding each individual circuit protector. In addition, the present load
current of the circuit breaker and the load voltage are transmitted to the superordinate control unit. A
parameterisable limit value allows creation of a warning threshold which advises the user of changing system
conditions.
The new generation of electronic overcurrent protection REX12D consists of the EM12D-TMB intelligent
supply module and the REX12D versions of electronic circuit protectors which can be mounted side by side
in optional numbers. The 12.5 mm wide modules feature push-in technology for wiring with press release
buttons and allow no-tool time-saving and maintenance-free wiring. The supply module is designed for DC
24 V and 40 A and accommodates max. 10 mm² with wire end ferrule as a plus (+) supply. On the load output
side the circuit protector can be wired with 2.5 mm².
It is exactly tailored to the various needs of the users. And what is more: no additional accessories are
required when connecting the individual components electrically and mechanically. This helps save time and
money!
