Honeywell DC-TDIL11 – 24V DC Digital Input IOTA Redundant Module | Experion PKS Series
Engineering Background
The DC-TDIL11 is a field-proven digital input IOTA (Input/Output Termination Assembly) designed for Honeywell’s Experion PKS (Process Knowledge System) distributed control architecture. As a redundant-capable termination module, it serves as the critical interface between field-level 24V DC discrete signals and the Experion C300 controller infrastructure, enabling high-availability process control in mission-critical industrial environments.
Product Positioning
Targeted at process engineers and automation procurement specialists managing DCS upgrades, spare-parts inventory, or greenfield installations, the DC-TDIL11 delivers OEM-grade reliability with the sourcing flexibility of an authorized secondary-market supplier. Konmask.com stocks verified units with full traceability documentation, supporting both emergency replacement and planned maintenance cycles.

Proven Application Environments
- Oil & Gas upstream/downstream process control (SCADA integration, wellhead automation)
- Petrochemical and refinery DCS infrastructure (Experion PKS C300 controller cabinets)

- Pharmaceutical batch process control systems requiring 21 CFR Part 11 compliance
- Pulp & paper and mining operations with high-availability redundancy requirements
- Water treatment and municipal utility SCADA/DCS hybrid architectures
Engineering Advantages
- Redundant IOTA Design: Supports hot-standby redundancy configurations, eliminating single points of failure at the field termination layer.
- 24V DC Compatibility: Directly interfaces with industry-standard 24V DC field devices — limit switches, proximity sensors, solenoid feedback contacts — without additional signal conditioning.
- Plug-and-Play Integration: Designed for seamless drop-in replacement within existing Experion PKS C300 I/O subsystems; no firmware changes required for like-for-like swap.
- High Channel Density: Maximizes cabinet space utilization, reducing overall footprint in marshalling enclosures.
- Robust Field Wiring Terminals: Screw-type terminals rated for industrial vibration and thermal cycling environments.
- Galvanic Isolation: Field-side isolation protects controller backplane from ground loops and transient surges.
System Architecture & Signal Flow
The DC-TDIL11 IOTA mounts within the Experion PKS I/O cabinet and connects directly to the C300 FIM (Field Interface Module) via the I/O Link bus. Field wiring terminates at the IOTA’s screw terminals, where 24V DC discrete signals are conditioned, isolated, and passed to the FIM for processing by the C300 controller. In redundant configurations, a secondary IOTA mirrors the primary, with automatic bumpless switchover managed by the Experion PKS redundancy manager — ensuring zero process interruption during module failure or maintenance.

Technical FAQ
Q: Is the DC-TDIL11 compatible with Experion PKS R500 and later releases?
A: Yes. The DC-TDIL11 IOTA is hardware-compatible across Experion PKS R400–R520 releases. Confirm FIM firmware revision with your system integrator for R530+ environments.
Q: Can this IOTA be used in a non-redundant (simplex) configuration?
A: Yes. The DC-TDIL11 supports both simplex and redundant IOTA configurations; redundancy is enabled via software parameter in the Experion Control Builder.
Q: What is the maximum cable length for field wiring to this IOTA?
A: Honeywell specifies a maximum of 300 m (1,000 ft) for 24V DC digital input wiring under standard installation conditions. Consult the Experion PKS I/O Installation Guide (Doc# EP-DS-0001) for derating in high-noise environments.
Q: Do you provide a Certificate of Conformance (CoC)?
A: Yes. A CoC is available upon request for all units. Please specify at time of order.
Q: What is the return policy?
A: 30-day return window for units in original, uninstalled condition. DOA (Dead on Arrival) units are replaced at no charge within 7 days of receipt.
