Product Description
The ANB10D-425/CU2N is a high-availability node chassis designed for the Yokogawa ProSafe-RS Safety Instrumented System (SIS). This rack-mount node unit provides the mechanical and electrical backbone for safety I/O module integration and serves as a communication hub for critical process safety data.
The unit is engineered for dual-redundant ESB (Extended Serial Backplane) bus architectures, ensuring continuous safety data transmission even if one communication path fails. This architecture is essential for maintaining SIL3-level process safety integrity.
The CU2N configuration includes the S9342FA ESB connector unit, enabling high-speed, fault-tolerant communication between safety control nodes and field I/O modules.
The -4 power configuration provides dual-redundant power supply modules, reducing single points of failure. The unit is designed for 220–240V AC industrial power environments and does not require explosion-proof housing for standard installations.

Application
The ANB10D-425/CU2N is widely used in large-scale industrial safety systems including:
-
Oil and gas refineries
-
Thermal and combined-cycle power plants
-
Petrochemical processing facilities
Typical applications include expanding Safety Control Station (SCS) I/O capacity to support:
-
Emergency shutdown buttons
-
Flame detection systems
-
Gas detection safety loops
This ensures that field safety signals are reliably transmitted to central safety logic controllers through fault-tolerant network architecture.
FAQ
Q1: What is the difference between ANB10D and SNB10D?
The ANB10D is primarily a system expansion node for ESB bus networks, while SNB10D units are more commonly associated with specific safety node processing architectures. Both are part of the ProSafe-RS ecosystem.
Q2: Are power cables included with the -4 power option?
Internal redundant power supply modules are included, but external AC power cords must be purchased separately according to regional plug standards.
Q3: Why is the unit relatively heavy?
The 10 kg weight is due to the industrial-grade chassis construction and dual power supply hardware designed for continuous 24/7 operation.
