Honeywell TC-OAV081 Replacement for Experion PKS C300

Product Overview

Honeywell TC-OAV081 Replacement for Experion PKS C300 – Smooth Migration from Legacy DCS

The Honeywell TC-OAV081 is an 8-channel analog output module engineered for the Experion PKS C300 DCS platform. As legacy Honeywell TDC 3000, PlantScape, and early Experion R100–R200 systems reach end-of-life, plant engineers and procurement teams are actively sourcing verified replacement units to sustain production continuity without committing to a full control-system overhaul. This listing provides a direct, wiring-compatible replacement for the TC-OAV081, backed by a 12-month warranty and pre-shipment functional testing.

The TC-OAV081 delivers 8 isolated 4–20 mA analog output channels, each configurable via the Experion PKS Control Builder environment. Output resolution is 12-bit, with a channel update rate compatible with the C300 controller’s standard scan cycle. The module seats directly into the Honeywell Series C I/O Link chassis — the same backplane used by companion modules such as the TC-IAH081 (8-ch AI HART) and TC-OAH081 (8-ch AO HART) — meaning no mechanical modification is required when swapping a failed or end-of-life unit.

Seamless Upgrade Solutions

A successful TC-OAV081 migration rarely involves a single module swap. In practice, field engineers replacing aging Experion PKS I/O cards typically address the surrounding system architecture at the same time. The TC-OAV081 shares its Series C I/O Link backplane with the TC-IAH081 8-channel analog input HART module and the TC-OAH081 HART-enabled analog output module — both of which are common co-replacements when an entire I/O cluster is being refreshed.

On the digital side, plants migrating from legacy HPM or ACE nodes often simultaneously upgrade TC-IDV161 16-channel digital input modules and TC-ODV161 digital output modules housed in the same control cabinet. Coordinating these replacements in a single maintenance window minimizes repeated shutdowns and reduces overall migration risk.

Communication infrastructure is equally critical. The C300 controller communicates over Fault-Tolerant Ethernet (FTE) — a redundant 100 Mbps switched Ethernet backbone. If your migration involves upgrading the controller itself, the C300 Controller Module (CC-PCNT01) and its associated IOTA (CC-TCNT01) termination assembly are the natural pairing. For plants still running legacy ControlNet or Modbus RTU segments, a Series C Communication Interface Module may be required to bridge legacy field devices to the updated Experion backbone.

Power distribution within the control cabinet should also be reviewed. The Series C I/O chassis draws regulated 24 VDC from a dedicated Honeywell PS-24VDC power supply module. Aging PSUs in legacy cabinets are a common failure point; replacing the PSU alongside the I/O modules eliminates a latent risk that could otherwise cause nuisance trips post-migration.

For field device connectivity, the TC-OAV081 interfaces to field instruments via a Field Termination Assembly (FTA) — typically the FC-FTAM-0002 or equivalent marshalling panel. Verifying FTA compatibility before ordering ensures the replacement module drops in without rewiring. Signal isolators or barriers may be required if intrinsically safe (IS) loops are present in the same cabinet.

Finally, commissioning a replacement AO module in an Experion PKS environment requires a licensed copy of Experion PKS Control Builder and a standard Ethernet programming connection to the C300 controller. No proprietary programming cable is needed — a standard CAT5e/CAT6 patch cable to the FTE switch is sufficient, which simplifies on-site commissioning compared to older TDC 3000 workflows that required dedicated HW programmer cables.

Retrofit Guidance FAQ

Q: Can I swap the TC-OAV081 directly without rewiring field cables?
A: In most C300 installations, yes — provided the existing FTA model matches the TC-OAV081’s pinout. Confirm the FTA part number before ordering. If the legacy FTA was designed for a different I/O card family, a replacement FTA may be required, but field wiring to the marshalling panel typically remains unchanged.

Q: Do I need to modify my Control Builder configuration after swapping the module?
A: No. The TC-OAV081 is recognized automatically by the C300 controller via the Series C I/O Link. Existing channel assignments, scaling parameters, and HART pass-through configurations are retained in the controller database and do not require re-entry after a hot-swap or cold-swap replacement.

Q: Is the TC-OAV081 compatible with HART field instruments?
A: The TC-OAV081 is a standard (non-HART) analog output module. If HART communication to field devices is required, the TC-OAH081 is the HART-enabled equivalent and should be specified instead.

Q: What communication protocol does the module use on the system side?
A: The module communicates with the C300 controller via the proprietary Series C I/O Link — a deterministic, fault-tolerant backplane bus. No additional protocol configuration is required at the module level.

Q: How much cabinet space does the TC-OAV081 require?
A: The module occupies a single slot in the standard Honeywell Series C I/O chassis. No additional DIN rail space or external termination block is needed beyond the existing FTA footprint.

Q: Can this module be used in a redundant I/O configuration?
A: The TC-OAV081 supports Experion PKS I/O redundancy when paired with a redundant C300 controller and the appropriate redundancy IOTA. Consult your Experion PKS system design documentation to confirm the redundancy topology before ordering.

Warranty Assurance

Every TC-OAV081 unit shipped from TOPNLMS undergoes a pre-shipment functional test covering channel output accuracy, backplane communication handshake, and power rail integrity. Units are shipped in anti-static packaging with individual test records available upon request.

12-Month Warranty Coverage: All units carry a full 12-month warranty from the date of shipment. Warranty coverage includes free replacement or full refund for any unit that fails under normal operating conditions. DOA (Dead on Arrival) claims are processed within 48 hours of receipt confirmation.

Procurement Assurance: Stock is maintained in Xiamen, China, with typical lead times of 3–7 business days for standard international shipments. Express DHL/FedEx options are available for urgent plant shutdowns. A proforma invoice, packing list, and certificate of conformance are provided with every order. For volume procurement or blanket purchase orders, contact our sales team directly.

After-Sales Support: Our technical team is available to assist with compatibility verification, FTA cross-referencing, and commissioning guidance. We support customers through the full replacement lifecycle — from pre-order compatibility checks to post-installation troubleshooting.
