Honeywell 8C-PDODAI – Digital Output Module | Experion PKS / TDC 3000 Platform
In process-critical environments where a single missed output signal can halt an entire production line, engineers specify hardware that has been proven across decades of continuous operation. The Honeywell 8C-PDODAI is a high-density digital output module engineered for the Experion PKS and TDC 3000 Distributed Control System platforms — Honeywell’s flagship process automation architectures deployed in refineries, chemical plants, power generation facilities, and pharmaceutical manufacturing worldwide.
At Konmask.com, we source, inspect, and supply the 8C-PDODAI to procurement engineers who require verified, traceable components with fast lead times and reliable technical support.

- Long Product Lifecycle: Honeywell’s extended support commitment for TDC 3000 and Experion PKS ensures long-term spare parts availability
System Architecture & Signal Flow
The 8C-PDODAI slots into the Honeywell PMIO I/O chassis and communicates with the C300 Controller or equivalent via the Fault-Tolerant Ethernet (FTE) backplane bus. Each of the 8 output channels drives a field device (solenoid valve, relay coil, motor starter, indicator lamp) through a dedicated termination assembly. The module’s onboard diagnostics continuously monitor output driver health and report status to the Experion PKS server, enabling predictive maintenance scheduling without process interruption.
Signal path: Experion PKS Server → C300 Controller → FTE Backplane → 8C-PDODAI → Termination Assembly → Field Device

Technical FAQ
Q: Is the 8C-PDODAI compatible with Experion PKS R500 and later releases?
A: Yes. The module is backward-compatible with Experion PKS R400 through current releases. Confirm firmware revision with your Honeywell system integrator for R500+ deployments.
Q: Can this module replace an older TDC 3000 digital output card?
A: The 8C-PDODAI is designed for the PMIO chassis used in Experion PKS migrations from TDC 3000. Consult Honeywell’s migration guide (document EP-DS-8C-PMIO) for slot-for-slot compatibility mapping.
Q: What termination assembly is required?
A: The 8C-PDODAI pairs with Honeywell’s standard PMIO termination assemblies. Contact Konmask.com to source the matching TA as a bundle.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes. A CoC and inspection report are available for all units upon request at time of order.
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 1 unit. Volume pricing is available for orders of 5 units or more.
