Yokogawa EB401-50-S1 is an evidence-bounded EB401 ER Bus Interface Master Module requested style configuration. Yokogawa documents EB401 and its -5, 0 and 1 suffix codes; the public table does not separately decode the requested S1 style marking.
- Verified base model: EB401
- Product type: ER Bus Interface Master Module (for FIO)
- Requested -5 code: Standard type with no explosion protection
- Following 0 code: Always 0
System role: It connects an ESB Bus Node Unit or Compact Field Control Unit to ER Bus remote nodes over a 10BASE2 ER-bus interface. Only facts stated by the cited Yokogawa material are published; sibling, successor and third-party data are not transferred. Architecture boundary: Supported host units listed by Yokogawa are ANB10S, ANB10D, AFF50S, AFF50D, AFV10S and AFV10D; two modules can form a dual-redundant ER bus. Publish EB401-50 family facts only; verify the physical S1 style marking and exact project compatibility before replacement. Before installation or replacement, verify the complete physical label, host equipment, companion hardware, wiring and approved commissioning procedure. Origin and HS code remain unpublished unless an exact manufacturer record or the physical package label establishes them.
Important Notice: Verify the complete Yokogawa EB401-50-S1 physical label and installed-system documentation before use.
