 eloFlex, the safety system that offers the configuration possibilities of modular systems.

eloFlex 471EFR…


eloFlex 471EFR... is a configurable safety relay with 4 independent safety inputs (2-channel) and 4 safety outputs (2-channel) as well as 4 control outputs. The internal logic link is configured specifically for each customer.

 

  • Up to 4 safety functions can be implemented in one device
  • The number of safety outputs (relays) can be set according to the individual requirement, making this a cost-effective solution.
  • Increased functionality using less space in the switch cabinet.
  • The units are tamper-proof as are pre-configured during ordering.
  • Economical and reliable by unique identification of configuration for maintenance, commissioning and service
  • Can be perfectly adapted to your application through various configuration options, offering maximum flexibility.
  • Up to 40 sensors can be connected via elobau interfaces for input expansion.

 

The following logic and

safety functions are available:
