General Information
The ESB Bus Coupler Module is a communication module designed to connect the Field Control Unit and the Node Unit for ESB Bus via the ESB bus. This module is compatible with the Field Control Unit for FIO (AFV30S, AFV30D, AFV40S, AFV40D, A2FV50S, A2FV50D, A2FV70S, A2FV70D).
By installing two modules in the Field Control Unit for FIO, a dual-redundant ESB bus can be configured. The EC402 features two ESB bus connector ports on the front and accommodates more connected nodes than the EC401, offering a longer transmission distance.
