Key Features & Benefits
This connector unit serves as a critical interface component in Yokogawa's distributed control architecture, enabling seamless integration between field I/O modules and control processors. The built-in terminator eliminates the need for external termination components, simplifying installation and reducing potential points of failure.
Signal Integrity: The CU2T terminator ensures proper impedance matching across the ESB network, preventing signal reflections and maintaining data accuracy even in electrically noisy industrial environments.
Power Distribution: Efficiently distributes regulated power to connected I/O modules while providing overcurrent protection and isolation to safeguard downstream components.
Application Scenarios
Ideal for process automation, manufacturing execution systems, and SCADA implementations where distributed I/O architecture is required. Common applications include:
- Chemical processing plants requiring hazardous area interfacing
- Oil & gas facilities with remote monitoring stations
- Power generation systems with distributed sensor networks
- Water treatment facilities with multi-zone control requirements
- Pharmaceutical manufacturing with validated system architectures
Integration & Compatibility
The SNB10D-213/CU2T seamlessly integrates with Yokogawa's CENTUM VP, ProSafe-RS, and STARDOM control platforms. It supports hot-swappable module replacement for minimal downtime during maintenance operations.
Installation Considerations
Mount the unit on standard 35mm DIN rail with proper spacing for heat dissipation. Ensure ESB cable shielding is properly grounded at one end only to prevent ground loops. Maximum cable run between nodes should not exceed 100 meters without repeaters.
