The Siemens 3RK1303-6ES84-3SA3-ZX95 is a control section for the ECOFAST R2SS system, fitted with a PROFIBUS DP-V1 interface and a finger-safe connection. It's the fieldbus-facing slice in a distributed safety I/O block — the part that handles the PROFIBUS communication and passes control signals to the ECOFAST motor starters downstream.
Integration context
The ECOFAST R2SS system is a modular, IP65-rated motor management solution for decentralized installation — think conveyor sections, packaging machines, or material-handling zones where running individual motor cables back to a central cabinet would be wasteful. The control section mounts directly onto the ECOFAST bus rail and connects to the PROFIBUS DP-V1 network via the standard M12 bus-in / bus-out connectors. Finger-safe connection means the power and signal terminations are shrouded against accidental contact, which simplifies panel-less or open-frame installations where operators may be nearby.
Sourcing posture
Because the lifecycle stage is current, this part is sourced through the standard Siemens distribution channel.
