Product Description:

The EL EtherCAT Terminals series includes the ELX9560, manufactured by Beckhoff. This power supply terminal feeds field voltage into adjacent intrinsically safe I/O modules on the bus. By occupying a single slot on the DIN rail EtherCAT strand, it establishes the internal supply rail required by subsequent ELX signal terminals while maintaining deterministic communication through the system backplane. Its role in industrial automation is to distribute isolated power to hazardous-area input and output segments without requiring separate wiring assemblies. The compact arrangement also allows compatible signal terminals to receive power through the established bus connection rather than through individual field supply connections.

The power bus uses galvanic isolation, so field-side transients do not couple into the EtherCAT backplane. Wiring is secured by a spring-force clamp that grips conductors without requiring torque adjustment. Safe operation extends to ambient temperatures up to +60 °C, and the surrounding cabinet must provide at least IP54 ingress protection. The terminal accepts solid or stranded conductors with cross-sectional areas beginning at 0.14 mm² and extending to a 1.5 mm² single-core limit. Conductors fitted with ferrules can have cross-sectional areas of up to 1.0 mm². Service tools fit into a 2 mm slot, allowing the clamp to be opened without disturbing adjacent wiring. Proper conductor preparation prevents exposed copper from remaining outside the terminal housing after insertion.

At the lower end of its operating range, the terminal remains functional at temperatures down to -25 °C, allowing installation in refrigerated or outdoor control panels when the required enclosure protection is maintained. Lead insulation may be removed up to the 9 mm maximum stripping length to provide secure conductor contact without leaving excess bare wire. A crimp sleeve with a cross-sectional area as small as 0.14 mm² maintains full clamp engagement for intrinsically safe loops. The protection circuit complies with Overvoltage Category II, making the terminal suitable for equipment connected to a local distribution network. Electrical feed-through is restricted to downstream ELX signal terminals, preventing standard I/O sections from interrupting the certified safety path. This arrangement keeps the intrinsically safe power segment separate from the standard EtherCAT terminal supply while preserving communication across the terminal assembly.
