Product Short Description
Product Name: ER Bus Interface Master Module
Product Introduction: The EB401-10 is an ER Bus Interface Master Module designed for Yokogawa CENTUM distributed control systems. It establishes deterministic communication between local control units and remote ER bus nodes. The module is engineered for Yokogawa proprietary ER bus architecture and is not intended for general Ethernet networking.
Description
Technical Specifications:
- Function: ER bus interface function
- Physical Layer: IEEE 802.3 10BASE-2 (1 port)
- Connector: BNC
- Communication Speed: 10 Mbps
- Transmission Distance: Max. 185 m (using YCB141 cable)
- Current Consumption: 0.7 A
- Dimensions: 32.8 × 144.65 × 125.5 mm
- Weight: 0.3 kg
- Certifications: CE, RoHS
- Model Suffix Options:
- -5: Standard type with no explosion protection
- -E: Standard type with explosion protection
- -1: With ISA Standard G3 option
System Compatibility: Integrates with ESB Bus Node Units (ANB10S/D) and Compact Field Control Units (AFF50S/D, AFV10S/D).
Structural Features: ER bus can be branched from FCU up to 4 segments. For single configuration, EB401 must be installed in an odd-number slot of ANB10 or AFF50, and must be covered with dummy module (ADCV01) on the right side.
Application Scenarios: Expansion of ER bus networks in CENTUM-based systems, remote I/O communication in process plants, redundant control architectures, chemical, oil & gas, power generation, and heavy industry facilities.
Installation & Usage Notes: Must be installed in an odd-numbered slot of the compatible control unit; requires an adjacent dummy module (ADCV01) on the right side for single configuration. Use Yokogawa YCB141 coaxial cable to ensure signal integrity and maximum transmission distance. Dual-module installation allows ER bus redundancy. Recommended cable: Yokogawa YCB141 coaxial cable.
