Channel-to-Channel Isolation and DCS Signal Distribution

Within the CENTUM architecture, the ANB10D node unit functions as a communication and power distribution platform for connected I/O modules. Field signals are processed through installed I/O modules while ESB bus communication transfers operational data between the node and the associated Field Control Station. The hardware supports redundant communication paths and redundant power inputs to maintain node availability during maintenance or component replacement activities.
