DeltaV™ S-series Serial Interface
PDP_DeltaV S-series Serial Interface
The S-series Serial Interface provides a connection between the DeltaV™ system and devices that support a serial protocol, such as Modbus or Allen Bradley’s Data Highway Plus.
The S-series Serial Interface is supplied with Modbus software drivers pre-loaded. DeltaV Serial Interface can also be installed as a redundant pair for critical applications needing the highest availability.

  • Provides Seamless Information interface
  • Plug-and-play installation saves money
  • Extends the life of existing equipment
  • The interfaces automatically detect the presence of the redundant terminal block and are autosensed by the system as a redundant pair
  • The system automatically switches to the "standby" card without user intervention, should a primary Serial Interface card fail.
