Product Description
The Yokogawa SNB10D-225/CU2N is a dual-redundant Safety Node Unit designed for use in ProSafe-RS Safety Instrumented Systems (SIS). It acts as a communication and interface hub between field I/O modules and the safety control unit, ensuring continuous, high-integrity data transmission through an ESB (Ethernet Safety Bus).
Engineered to meet SIL 3 safety integrity standards, this unit ensures uninterrupted operation in safety-critical environments such as oil & gas, chemical processing, and power generation facilities. The dual-redundant power supply and node expansion capability further enhance system resilience. Its wide temperature tolerance (–20°C to +70°C) and ISA G3 environmental rating guarantee reliable performance under harsh industrial conditions.
