•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
