Emerson PK0750R-B DeltaV PK750 Redundant Controller Assembly without Traditional Local I/O Overview

  • Redundant PK750 controller pair without traditional local I/O
  • 750-DST capacity in the active and standby architecture
  • Two blank covers instead of local-I/O power modules

PK0750R-B combines two controllers, one carrier, two IOPs, and two blank covers as the no-local-I/O redundant order.


The paired controllers provide active and standby roles while the project uses remote or Ethernet-connected signal paths.


Redundancy, cabinet power, and remote-I/O ownership must be engineered together because the B assembly omits traditional local-I/O power hardware.

Apter Power supports PK0750R-B assembly verification, technical documentation, and quotation coordination.

Important Notice: Confirm the redundant B-suffix assembly, remote-I/O design, and complete two-controller hardware scope before ordering.
  • DST envelope: PK0750R-B supports as many as 750 device signal tags.
  • Scheduled execution: Control modules can run from 25 ms to 60 seconds according to process need.
  • Ethernet device limit: P01 supports as many as 64 package-network devices.
  • OPC UA service: Native server access requires no separate license and consumes no DSTs.
  • Local-I/O boundary: Traditional local I/O is not included in the PK0750R-B assembly.
  • Controller pair: Two controllers and one carrier define the redundant order base.
  • Remote ownership: Both controller roles must recognize the same remote or Ethernet-connected I/O assignments.
  • Switchover readiness: Partner synchronization must be established before controlled process release.
  • Modbus TCP: Client and Server roles support package and supervisory devices.
  • EtherNet/IP: The Scanner role communicates with adapter devices through P01.
  • PROFINET: The Controller role uses the integrated PN1 interface.
  • DeltaV networks: Primary and secondary control-network paths support the paired controller architecture.
  • Remote-I/O process units: PK0750R-B supports redundant control without traditional local-I/O power hardware.
  • CHARM architectures: Electronic marshalling can connect field signals to the redundant project.
  • Ethernet package systems: Supported protocol roles link PLCs, drives, analyzers, and skid equipment.
  • Continuity-focused utilities: Active and standby control can be applied where remote I/O is the selected field architecture.
Description
The PK0750R-B is Emerson’s redundant PK750 assembly for DeltaV projects that use remote or Ethernet-connected I/O instead of traditional local I/O. Its ordered set includes two controllers, one carrier, two I/O ports, and two blank covers, with no local-I/O power modules.

The PK0750R-B provides paired controller hardware for active/standby operation while supporting up to 750 device signal tags and module execution rates from 25 milliseconds to 60 seconds. Both the redundancy plan and the no-local-I/O cabinet strategy must match the installed system before this order model is released.

Technical notes
PK0750R-B combines two decision boundaries: redundant controller operation and an assembly with no traditional local-I/O power modules. Confirm partner synchronization, controller roles, remote-I/O ownership, and cabinet power before release; stop commissioning if either controller cannot recognize its partner or the intended I/O path.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What hardware is included with PK0750R-B?
PK0750R-B includes two PK750 controllers, one carrier, two I/O ports, and two blank covers. It does not include power modules for traditional local I/O.
Can PK0750R-B be used where traditional local I/O carriers are installed?
Not without redesign. This assembly is ordered without local-I/O power hardware, so verify the complete field-I/O and cabinet-power strategy before substitution.
What must be verified for PK0750R-B redundancy?
Confirm both controllers are the correct order model, the active and standby roles are recognized, synchronization completes, network paths are healthy, and switchover behavior is tested.
How should PK0750R-B be identified in an RFQ?
State the exact PK0750R-B model, redundant architecture, no-local-I/O requirement, installed DeltaV release, and intended remote-I/O paths.
How many Ethernet devices can PK0750R-B manage on port P01?
Port P01 supports up to 64 Ethernet devices. Validate protocol roles, switch topology, addressing, update rates, and failover recovery for both controller states.
Does OPC UA Server use capacity on PK0750R-B?
Yes. OPC UA Server requires the applicable license and consumes device signal tag capacity. Include its load when sizing the 750-DST controller.
What should be tested after installing PK0750R-B?
Verify active/standby indication, synchronization, control-network health, remote-I/O ownership, alarms, interlocks, and a controlled switchover before returning the process to service.
