Product Description
The SNB10D-215/CU2N is a high-reliability Safety Node Unit (SNU) designed for the Yokogawa ProSafe-RS Safety Instrumented System (SIS). It serves as a localized expansion hub for safety I/O modules, linking field sensors and actuators to the main safety controller over the ESB bus.
With a dual-redundant architecture, the SNB10D-215/CU2N (Part Number: SNB10D-215/CU2N) eliminates single points of failure, ensuring that critical safety loops remain operational during maintenance or component faults.

Advanced System Role
The SNB10D-215/CU2N is essential for distributed safety architectures, allowing I/O to be physically separated from the controller to reduce wiring complexity and satisfy zone-specific installation requirements.
The CU2N option indicates a specialized connector unit configuration optimized for ProSafe-RS. Its passive cooling and G3 conformal coating make it suitable for installation in remote instrument enclosures (RIEs) near process areas.
Frequently Asked Questions
How does dual redundancy operate in this node unit?
The unit contains two independent power supply modules and two ESB bus interface ports. If one power source fails or an ESB cable is compromised, the node continues communication and safety logic execution without tripping the system.
Is this node compatible with standard CENTUM VP I/O modules?
No. Although the form factor may resemble FIO nodes, the SNB10D is designed exclusively for SIL 3 safety-certified I/O modules in ProSafe-RS systems.
