System Architecture & Signal Flow
The KJ3241X1-BA1 installs directly into a DeltaV I/O carrier slot. Field serial devices connect to the module’s terminal block via shielded twisted-pair cable. The module converts serial data frames to DeltaV’s internal I/O bus protocol, making device parameters available as standard DeltaV parameters accessible from any DeltaV controller or workstation on the network. Signal isolation is maintained between the field-side serial interface and the DeltaV backplane bus, protecting system integrity.
