Where This Product Is Used
The Honeywell 83957061-002 Digital Output Relay Module is engineered for mission-critical process automation environments where reliable discrete relay switching is essential. Typical deployment sites include:
- Oil & Gas Refineries – Actuating solenoid valves, motor starters, and shutdown relays in SCADA/DCS-integrated control loops
- Chemical & Petrochemical Plants – Driving on/off control of pumps, agitators, and safety interlock circuits
- Power Generation Facilities – Interfacing DCS logic outputs to field-level switchgear and breaker control panels
- Pulp & Paper Mills – Coordinating conveyor drives and process equipment via relay contact closure
- Pharmaceutical Manufacturing – Controlling cleanroom HVAC dampers and batch process actuators under cGMP conditions
- Water & Wastewater Treatment – Switching pump stations and valve actuators from centralized Honeywell TDC-3000 control rooms

Why Engineers Specify This Model
- Drop-in Replacement – Direct OEM-compatible replacement for aging TDC-3000 I/O racks without controller reconfiguration
- Relay Contact Isolation – Galvanically isolated relay outputs protect DCS backplane from field-side voltage transients
- Proven Field Reliability – Honeywell’s TDC-3000 platform has decades of proven uptime in tier-1 process industries worldwide
- Reduced Downtime Risk – Stocking this module as a spare eliminates extended lead times during unplanned outages
- Broad Field Compatibility – Relay contacts interface directly with 24 VDC and 120/240 VAC field devices without additional signal conditioning
Complete System Bill of Materials
For a fully operational Honeywell TDC-3000 digital output relay loop, engineers typically specify the following alongside the 83957061-002:
- Honeywell Field Termination Assembly (FTA) – DO Relay type (e.g., 51304485-100 or equivalent)
- Honeywell IOP Extender Cable (if remote mounting)
- Honeywell Universal Control Network (UCN) or Local Control Network (LCN) node card
- Marshalling cabinet with DIN rail terminal blocks (24 VDC or 120 VAC rated)
- Surge protection modules for field wiring (recommended for long cable runs)
- Spare fuses per FTA specification
Compliance & Industry Standards

Application-Specific FAQ
Q: Is the 83957061-002 compatible with both TDC-3000 and TPS (TotalPlant Solution) platforms?
A: Yes. The TPS platform is the evolved successor to TDC-3000 and maintains backward I/O compatibility. This module operates in both environments when paired with the correct FTA.
Q: Can this module be used in a Safety Instrumented System (SIS)?
A: The 83957061-002 is a standard process control I/O module. For SIL-rated SIS applications, Honeywell’s Safety Manager platform with certified I/O modules should be specified. Consult your functional safety engineer.
Q: What is the difference between -001 and -002 revision suffixes?
A: Honeywell uses dash-number suffixes to denote hardware revisions or configuration variants (e.g., channel count, contact rating, or firmware). Always cross-reference the OEM compatibility matrix or contact us to confirm interchangeability for your specific rack revision.
Q: Do you offer a warranty on surplus Honeywell modules?
A: Yes. Konmask provides a 12-month warranty covering defects in materials and workmanship. DOA (Dead on Arrival) units are replaced at no charge within 30 days of receipt.
Q: Can you supply multiple units for a plant-wide spare parts program?
A: Absolutely. We support bulk procurement and consignment stocking programs. Contact us with your BOM for a volume pricing proposal.
