The EtherCAT terminals in the ELX series include analog input terminals with built-in TwinSafe single-channel (SC) technology. These compact I/O terminals can be used to support applications in hazardous areas that require both intrinsically safe signal transmission and functional safety capabilities. The space-saving terminals, which are certified in compliance with ATEX and IECEx standards, enable direct connection of intrinsically safe field devices through to Zone 0/20 based on an integrated safety barrier. The terminal designs extended by TwinSafe SC technology make it possible to achieve a safety level equivalent to PLd/Cat. 3 according to EN ISO 13849-1 or SIL 2 according to EN 62061.
