订购热线：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.
