You can find the technical specs in the PK Controller Product Data Sheet:
www.emerson.com/.../deltav-pk-controller-en-3583460.pdf

You need to contact Local Business Partner or Emerson Sales office for pricing because there are many factors that go into the cost - Standalone vs Connected to DeltaV, connecting to new or exisiting DeltaV system and PLC being connected to DeltaV, are a few examples of the factors for pricing.

We all know about the discount price politics of Emerson. But it were helpfull to get the list price of this controller for an imagine about.
It seems to be a very powerfull Ctrl, which I missed many times where we had to handle additional i.e. Packing machines etc. or other fast mechanical process with 100ms control module.
This is the right bridge between DCS and PLC and the offer as an stand alone System is the right for small plants with limited IO, similar to the Plantweb solutions. Hope - Emerson will be also generous with the price. I ask several Sales Guys international and no one could tell me the price up to now.
