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.
Cost-effective 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
Additional sensors can be connected via elobau interfaces for input expansion

The following logic and safety functions are available:

Logic link:	Safety functions:
AND	t_ON / t_OFF
OR	Safetyfunction
XOR	2-hand
NAND	Safetygate
NOR	E-stop
XNOR	N.O./N.O.
NOT	or N.O./N.C.

eloFlex 471 EFR… is a configurable safety relay with 4 independent safety inputs (2-channel) and up to 4 safety outputs as well as 4 control outputs.

The internal logic link is configured specifically for each customer.
