Analog Output DCS Solution – Honeywell DC-TAIL51 | TotalPlant Solution IOTA Series
Where This Product Is Used
The Honeywell DC-TAIL51 is a 24V DC Analog Output IOTA (I/O Termination Assembly) Module engineered for Honeywell’s TotalPlant Solution (TPS) Distributed Control System. It is deployed across process-critical industries where precise analog signal conditioning and field termination are essential:
- Oil & Gas Refineries – Control valve positioners, flow control loops, and pressure regulation in upstream/downstream processing units.
- Petrochemical & Chemical Plants – Analog output signals to modulating control valves in reactor temperature and feed-rate control systems.
- Power Generation – Turbine governor control, boiler feedwater regulation, and load dispatch analog output channels.
- Pulp & Paper Mills – Consistency control, headbox pressure, and stock flow analog output loops.
- Pharmaceutical Manufacturing – Bioreactor temperature and pH control via 4–20 mA analog output to field instruments.
- Water & Wastewater Treatment – Pump speed control via VFD analog reference signals and chemical dosing control.

Why Engineers Specify This Model
- Direct TPS Compatibility – Native termination assembly for Honeywell TPS/PlantScape HPM I/O subsystems; no adapter or signal converter required.
- 24V DC Field Power – Onboard 24V loop power supply simplifies field wiring for 2-wire transmitters and valve positioners.
- High Channel Density – Supports multiple analog output channels per IOTA board, reducing panel footprint and wiring complexity.
- Proven Field Reliability – Widely deployed in SIL-rated and non-SIL process control environments with documented MTBF performance.
- Hot-Swap Ready – Supports module replacement without full system shutdown when used with compatible HPM card file configurations.
- Backward Compatibility – Interoperable with legacy TPS and PlantScape installations, protecting existing capital investment.

Application-Specific FAQ
Q: Is the DC-TAIL51 compatible with Honeywell PlantScape as well as TPS?
A: Yes. The DC-TAIL51 IOTA is designed for use across both TotalPlant Solution (TPS) and PlantScape DCS platforms sharing the HPM I/O architecture.
Q: Can this module be used in a SIL 2 safety loop?
A: The DC-TAIL51 is a standard process control IOTA and is not independently SIL-certified. For safety-rated analog output, Honeywell’s FSC (Fail-Safe Controller) series should be specified.
Q: What is the difference between an IOTA and an FTA in Honeywell terminology?
A: IOTA (I/O Termination Assembly) is the Honeywell TPS-specific term for the field termination board connecting field wiring to the I/O card. FTA is the equivalent term used in newer Honeywell Experion PKS systems.
Q: Do you supply the mating I/O card (e.g., MC-TAOY22) as well?
A: Yes. Konmask.com stocks a broad range of complementary Honeywell TPS I/O cards and cables. Contact us with your full BOM for a consolidated quotation.
Q: Can I return a module if it does not match my system revision?
A: Yes. We accept returns within 30 days for unused modules in original packaging. Please confirm your HPM firmware and card file revision before ordering.
