CENTUM VP N-IO / FIOESB Bus Coupler Module
ONE-PORT ESB COUPLER · STANDARD NON-EX TYPE · ISA G3 OPTION
Yokogawa EC401-51 CENTUM VP One-Port ESB Bus Coupler Module
A one-port ESB bus coupler for Yokogawa N-IO and FIO hardware, configured as the standard non-explosion-protected type with the G3 option.
PRODUCT CONTEXT
Product Profile
EC401-51 is an EC401 one-port ESB bus coupler for N-IO and FIO. The -5 selection identifies the standard type without explosion protection, while the final 1 identifies the ISA Standard G3 environmental option.
The module sits in a defined ESB bus path. Coupled node hardware, cable, port allocation, style number and system engineering data therefore control replacement acceptance.

CUSTOMER QUESTIONS
FAQ
What should accompany an EC401-51 enquiry?
Provide the complete -51 label, style number, node model, slot, ESB cable path, SEM use and requested quantity.
Can EC401-50 replace EC401-51?
Do not assume so; the final 1 identifies the G3 option and must agree with the installed environmental requirement.
Why is the style number important for EC401-51?
Yokogawa specifies style 2 or later when EC401 is used with Sequence of Events Manager over Vnet/IP.
Does EC401-51 identify an explosion-protected execution?
No. The -5 selection is the standard type without explosion protection.
What proves EC401-51 is ready after service?
Normal module indications, stable ESB traffic and correct recognition of every configured N-IO or FIO component are required.
