TwinSAFE safety controllers permit optimal adaptation to an individual machine’s concept’s specific safety requirements. The ability to distribute an entire safety application’s intelligence across multiple TwinSAFE Logic-capable I/O modules means flexible implementation of modular architectures. The latest I/O components are EL1918 TwinSAFE EtherCAT terminal, a digital terminal with eight safe inputs; EL2911 TwinSAFE EtherCAT terminal, a safe potential supply terminal with four safe inputs and one safe output; and EP1957-0022 TwinSAFE EtherCAT box, an IP67-protected digital combi module with eight safe inputs and four safe outputs. These I/O modules can be used as controllers for the direct execution of customer-specific safety projects.
