GENERAL
The Yokogawa EC401-11 ESB Bus Coupler Module is a communication module designed to connect the Field Control Unit and the Node Unit via the ESB Bus.
This module can be installed in various Field Control Units, including AFV30S, AFV30D, AFV40S, AFV40D, A2FV50S, A2FV50D, A2FV70S, and A2FV70D.
Dual-redundant ESB Bus configurations can be achieved by installing two modules in the Field Control Unit for FIO.
STANDARD SPECIFICATIONS
- Function: ESB bus interface function
- Number of connectable units: Maximum 9 units (*1)
- Transmission speed: 128 Mbps (I/O module data transmission)
- Transmission distance: Maximum 10 meters
- Current consumption: 0.5 A
- Weight: Approximately 0.24 kg
(*1: The number of ANB10S, ANB10D, ANT401, ANT411, and ANT421 units that can be connected to EC401 is up to 9.)
If the ESB bus is non-redundant, the ESB Bus Coupler Module must be installed in the 7th slot of compatible units such as AFV30S, AFV30D, AFV40S, AFV40D, A2FV50S, A2FV50D, A2FV70S, and A2FV70D. Slot 8 must be covered with a dummy module.
For dual-redundant ESB bus configurations, modules need to be installed in both the 7th and 8th slots.
Only the style code S3 or later of EC401 can be combined with the processor module CP471.
REQUIREMENTS FOR USING SEM (Sequence of Events Manager)
