Industrial Control Solution – Honeywell DO-1224 | Digital Output Module
Where This Product Is Used
The Honeywell DO-1224 is a 24-channel digital output module engineered for deployment in distributed control systems (DCS) across the most demanding industrial environments. Engineers specify this module in:
- Oil & Gas Processing Plants – Controlling solenoid valves, motor starters, and shutdown actuators in upstream/downstream facilities
- Chemical & Petrochemical Plants – Driving discrete field devices in safety-critical process loops
- Power Generation Facilities – Managing turbine auxiliary systems, breaker control, and alarm annunciators
- Pulp & Paper Mills – Coordinating conveyor drives, pump starters, and valve actuators
- Water & Wastewater Treatment – Activating pumps, blowers, and dosing systems via DCS command
- Pharmaceutical Manufacturing – Controlling cleanroom HVAC dampers and process isolation valves under GMP conditions

Why Engineers Specify This Model
The DO-1224 is a proven workhorse in Honeywell DCS architectures. Key reasons it remains the preferred choice for control engineers:
- High Channel Density: 24 discrete outputs per card minimizes chassis slots and reduces total system footprint
- Direct Backplane Integration: Plug-and-play compatibility with Honeywell TDC 3000, TPS, and Experion PKS platforms — no additional interface hardware required
- Optical Isolation: Protects the controller backplane from field-side voltage transients and ground loops
- Proven Field Reliability: Widely deployed in brownfield plants with 10–20+ year operational histories
- Hot-Swap Capable: Supports live replacement in redundant DCS configurations to minimize process downtime
- Diagnostic Support: On-card LED status indicators for rapid field troubleshooting without test equipment

Application-Specific FAQ
Q: Is the DO-1224 compatible with Experion PKS?
A: The DO-1224 is a legacy Honeywell I/O card designed for TDC 3000 / TPS platforms. Compatibility with Experion PKS depends on the I/O chassis and FTA configuration — contact us to confirm your system revision.
Q: Can this module be used in a Safety Instrumented System (SIS)?
A: The DO-1224 is a standard process I/O card. For SIL-rated SIS applications, Honeywell’s Safety Manager platform with certified I/O modules is recommended. Consult your functional safety engineer.
Q: What is the difference between DO-1224 and DO-1216?
A: The DO-1224 provides 24 output channels versus 16 on the DO-1216, offering higher density for applications with more discrete field devices per chassis slot.
Q: Do you supply the matching Field Termination Assembly (FTA)?
A: Yes. Contact us with your DO-1224 revision and we will identify the correct FTA part number for your installation.
Q: What warranty applies to this module?
A: We offer a standard 90-day functional warranty on all modules. Extended warranty options are available — inquire at time of order.
