Product Description
The Yokogawa SNB10D-225/CU2T is a rack-mountable safety node unit built for the ProSafe-RS Safety Instrumented System (SIS). It acts as the central interface between field I/O devices and the safety control processor, handling analog and digital signal transmission via the Enhanced System Bus (ESB).
This robust unit integrates a dual-redundant power supply and a CU2T connector with ESB terminator, ensuring stable signal communication and uninterrupted operation in safety-critical environments. The SNB10D-225/CU2T meets IEC 61508 SIL3 standards, making it ideal for emergency shutdown, fire and gas protection, and process safety control.
The module features remote diagnostics, output calibration, and grounding checks, which simplify maintenance and fault detection. With its wide –20 °C to +70 °C operating range, ISA G3 compliance, and rugged rack-mount structure, the unit delivers long-term reliability even in extreme conditions.
