Product Description
The SNB10D-213/CU2N is a high-reliability Safety Node Unit designed for the Yokogawa ProSafe-RS platform.
This module functions as a remote safety I/O expansion and communication node, enabling distributed safety signal processing while maintaining deterministic and secure communication with the safety control station.
Engineered for SIL3 safety integrity level applications, the SNB10D-213/CU2N supports critical protection logic execution for:
-
Emergency Shutdown (ESD) systems
-
Fire & Gas (F&G) safety systems
-
Process interlock safety loops
The unit acts as a communication backbone for distributed safety architectures using ESB Bus and Vnet/IP protocols, ensuring high-speed, fault-tolerant data transmission.
Designed for mission-critical industries such as hydrocarbon processing and power generation, the module supports:
-
Redundant communication paths
-
Hot-swappable power architecture
-
Modular safety I/O expansion without interrupting active safety loops

Safety System FAQ
Does the SNB10D-213/CU2N support SIL3 applications?
Yes. When deployed within a certified ProSafe-RS safety architecture, this node unit meets SIL3 hardware and software requirements under IEC 61508 compliance guidelines.
How does the SNB10D-213/CU2N handle communication failures?
The unit features dual-redundant communication ports. If one communication path fails due to cable damage or hardware fault, the system automatically switches to the backup path to maintain safety monitoring and control continuity.
