ABB SA167 (3BSE003390R1) – Signal Adapter/Interface Module for ABB DCS I/O Wiring

The ABB SA167, part number 3BSE003390R1, is a practical signal adapter used in ABB distributed control system cabinets to tidy up field wiring and link it reliably to the I/O side. From my experience, SA-series parts like this are often specified as drop-in replacements during preventive maintenance or when standardizing mixed cabinets. You might notice that the SA167 typically sits between field terminals and the I/O harness/backplane, keeping turnaround time short when you have to swap or add points under a tight outage window.

Our Order Process and Guarantees

• Warranty: 365 days
• Lead time: 1 week for in‑stock items; no more than one month at the latest
• Payment: 50% advance payment, full payment before delivery
• Express options: FedEx, UPS, DHL

Key Features

• Purpose-built interface: Designed to adapt field signals to the ABB I/O side with neat, serviceable termination.
• Drop-in replacement: In many cases, SA167 can be swapped during a live maintenance window with minimal rewiring.
• Robust industrial design: Mechanical layout and terminals are suited for cabinet environments subject to vibration and electrical noise.
• Consistent labeling: Clear marking typically reduces wiring errors and simplifies loop checks.
• Compatible with ABB DCS cabinets: Commonly applied in ABB Advant/800xA ecosystems where a dedicated signal adapter is required.
• Low upkeep: No firmware to manage; routine torque and visual checks are usually enough.

Technical Specifications

Application Fields

The SA167 is commonly used where ABB DCS cabinets require structured, documented signal handoff between field devices and the I/O side. Typical sites include:

• Oil & gas processing units and pipeline stations
• Chemical and petrochemical plants
• Power generation (thermal, combined cycle)
• Pulp & paper and wood products mills
• Metals, cement, and mining operations
• Water and wastewater treatment plants

One thing I appreciate is how these adapters help during brownfield upgrades—teams can migrate I/O in phases without tearing out proven field cabling. A maintenance supervisor told us the SA-style layout “kept loop checks predictable” during a weekend turnaround, which seems to be a common theme.

Advantages & Value

• Reliability: ABB-grade hardware intended for industrial cabinets and 24/7 duty.
• Compatibility: Aligns with ABB wiring practices, which typically shortens commissioning time.
• Cost control: Reduces rework on field wiring and helps avoid unscheduled downtime.
• Lifecycle support: Suitable as a direct spare, keeping installed bases standardized.
• Technical support: We can help verify cabinet drawings and part matching before you place the order.

Installation & Maintenance

• Cabinet environment: Mount in a clean, dry control cabinet with adequate ventilation; avoid conductive dust.
• Wiring: Follow the ABB wiring schedule; confirm terminal assignments and shield routing; torque terminals per ABB spec.
• ESD safety: Handle using ESD precautions; isolate power to adjacent I/O before working on terminations.
• Checks after installation: Perform continuity and polarity checks, then run loop verification with the DCS.
• Routine maintenance: Periodic visual inspection for loosened terminals; re-torque during scheduled outages.
• Documentation: Update cabinet drawings and I/O lists whenever channels are repurposed or added.

Quality & Certifications

• Manufactured under ABB quality systems (ISO 9001 at the manufacturing level)
• CE conformity typically applicable for cabinet components
• RoHS compliance according to ABB material declarations
• Manufacturer warranty policies apply; our supply carries a 365-day warranty

Tip: If you’re matching an existing cabinet, share photos of the current adapter and terminal layout along with the loop list. It usually speeds up verification and avoids mix-ups between similar SA-series parts.
