Yokogawa EC402-50 ESB Bus Coupler Module (for AFV30/AFV40, 2-Port）

The ESB Bus Coupler Module is a communication module to connect the Field Control Unit and the Node Unit for ESB Bus via the ESB bus.

This module can be installed in the Field Control Unit for FIO (AFV30S, AFV30D, AFV40S, AFV40D).
By installing two modules in the Field Control Unit for FIO, dual-redundant ESB bus can be configured.
EC402 has two ESB bus connector ports on the front of the module and accommodates a larger number of
connected nodes than EC401, so it can offer a longer transmission distance.

STANDARD SPECIFICATIONS
Function: ESB bus master interface function
Number of connectable nodes (*1): Upper side : Max. 9 units, Lower side : Max 9 units, Total: Max. 13 units.
Transmission speed: 128 Mbps (I/O module data transmission)
Transmission distance: Upper side: Max. 10 m, Lower side: Max. 10 m, Total: Max. 20 m
Current consumption: 0.5 A
Weight: 0.24 kg
*1: This varies depending on the FCS database.

If ESB bus is non- redundant, the ESB Bus Coupler Module needs to be installed in the 7th slot of AFV30S, AFV30D,AFV40S, or AFV40D and slot 8th must be covered by a dummy module.
And when ESB bus is dual-redundant, the modules need to be installed in both the 7th and 8th slots.
