ABB DSTXW110 57160001-AAP – High-Performance Temperature Transmitter for Industrial Process Control

If you’re working on a process automation setup where precise temperature signal conditioning matters—especially in oil & gas, chemical, or power generation—one thing I appreciate about the ABB DSTXW110 is how consistently it handles RTD and thermocouple inputs without breaking a sweat. It’s not flashy, but in environments where signal drift or noise can throw off entire batches, this transmitter typically delivers stable, accurate outputs over long cable runs.

Key Features

• Universal input support: Handles RTDs (Pt100, Ni100) and multiple thermocouple types (J, K, T, etc.), which simplifies inventory if you’re managing varied sensor types across plants.
• Two-wire loop-powered design: Draws power from the 4–20 mA loop, so you don’t need a separate power supply—helps reduce wiring complexity in retrofit installations.
• HART 7 communication: Allows remote configuration and diagnostics via HART protocol, which in many cases reduces downtime during calibration checks.
• High EMC immunity: Performs reliably even in electrically noisy environments like near VFDs or high-voltage switchgear.
• DIN rail mounting with spring clamp: Tool-free installation and removal, making field replacement faster than screw-terminal alternatives.

Technical Specifications

Application Fields

This transmitter seems to be most commonly deployed in continuous process industries. From my experience, it’s frequently found in reactor temperature monitoring in chemical plants, boiler feedwater control in power stations, and custody transfer heating systems in upstream oil & gas. One customer mentioned using it in a biogas facility where ambient temps swing wildly—it held calibration through seasonal changes without issue. Its compact size also makes it suitable for tight junction boxes or local instrument panels near the sensor.

Advantages & Value

Procurement teams tend to favor this model because it balances performance with longevity. While there are cheaper transmitters out there, the ABB build quality usually means fewer field failures and lower lifecycle costs. Compatibility with standard HART tools means your technicians likely won’t need extra training. And since ABB maintains strong backward compatibility across generations, upgrading individual units in older systems tends to go smoothly. In many cases, the time saved during commissioning alone justifies the slight premium.

Installation & Maintenance

You’ll want to mount this on a standard 35 mm DIN rail inside an IP-rated enclosure—especially if exposed to moisture or dust. Make sure the cabinet has adequate ventilation if ambient temps exceed 60 °C, though the unit itself is rated higher. Wiring is straightforward: use twisted-pair shielded cable for the sensor leads, and ground the shield at one end only to avoid ground loops. For maintenance, we typically recommend checking zero/span every 12 months using a HART communicator, and inspecting terminals for corrosion in humid environments. Firmware updates are rare but possible via HART interface if needed.

Quality & Certifications

The DSTXW110 carries CE, UL, and ATEX/IECEx certifications for use in hazardous areas (check specific variant markings). It’s RoHS compliant and designed to meet IEC 61326-1 for electromagnetic compatibility. ABB backs it with a standard 365-day warranty against manufacturing defects. We’ve seen these operate reliably for 10+ years in well-maintained systems, though extreme thermal cycling may affect long-term stability.
