Features:

  • Supports both RTD sensors (Pt100, Pt1000, Ni100) in 2/3/4-wire configurations and thermocouple types B, E, J, K, L, N, R, S, T, covering virtually all industrial temperature measurement needs.
  • Each of the 4 input channels is independently isolated, preventing electrical faults, ground loops, or noise on one channel from affecting other channels or the system backplane, ensuring measurement integrity.
  • Part of ABB's 800xA DCS ecosystem with RoHS compliance and no batteries for simplified maintenance.
The AI950N 3KDE175523L9500 is designed to accommodate the full range of industrial temperature sensors, making it a versatile solution for process measurement. For Resistance Temperature Detectors (RTDs), it supports Pt100 (the most common industrial standard), Pt1000 (higher resistance for lower lead wire error), and Ni100 (nickel-based for specific applications). The module accepts 2-wire (simplest but with lead resistance error), 3-wire (cancels lead resistance, most common in industry), and 4-wire (highest accuracy for laboratory-grade measurements) connection technologies.

The AI950N 3KDE175523L9500 features independent galvanic isolation on each of its four input channels. In industrial environments, temperature sensors are often located hundreds of meters from the control system, running through conduit trays alongside high-voltage power cables, motor leads, and variable frequency drive wiring. These conditions can induce ground loops, common-mode voltages, and electrical noise that corrupt low-level temperature signals—particularly from thermocouples which produce only microvolt-level signals. Channel-by-channel isolation means that a short circuit or voltage spike on one sensor input will not propagate to other channels or, more critically, to the system backplane where it could damage the controller.

The AI950N 3KDE175523L9500 is designed for high-density installation within ABB's S900 I/O system. With dimensions of just 104mm width, 20mm height, and 104mm depth, and weighing only 0.13 kg, this module occupies minimal space in control cabinets. The 20mm height (approximately 0.8 inches) is particularly noteworthy—traditional I/O modules are often 100mm or taller. This slim profile allows the S900 system to pack more I/O channels per rack, reducing overall cabinet size and footprint. For large distributed control systems with thousands of I/O points, this space savings translates directly to lower enclosure costs, reduced floor space requirements, and simpler installation.

The AI950N 3KDE175523L9500 ABB I/O Temperature Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Oil & Gas: Temperature data acquisition in non-explosive control rooms or auxiliary utilities (e.g., cooling water and lube oil systems).
  • Chemical & Pharmaceutical: High-precision monitoring of reaction vessels (safe zones), storage tanks, heated jackets, and blending systems.
  • Power Generation: Tracking critical temperatures in generator bearings, boiler peripherals, and transformer cooling systems.
  • Metal & Cement Processing: Monitoring ambient and auxiliary processing temperatures near high-temperature blast furnaces and rotary kilns.
  • Galvanic Isolation: Complete electrical isolation between channels, and between the channels and the internal system bus. This prevents ground loops and safeguards core electronics from field surges.
  • Overvoltage & Reverse Polarity Protection: Input circuits are hardened to survive minor wiring faults and voltage spikes coming from the field.
  • Short Circuit Monitoring: Detects shorted field lines, protects internal circuitry, and transmits an error code to the controller.
  • Zone Restrictions: Must be mounted strictly within a Safe Area. If your sensors are located in hazardous zones (Zone 1 or Zone 2), you must use the intrinsically safe variant (AI950S) or utilize external safety barriers.
  • Hot Swapping Capability: The S900 system fully supports hot swapping. The termination unit (terminal block) features an integrated disconnect mechanism. You can pull or plug the AI950N module under power without interrupting the operations of adjacent modules on the same rack.
  • Field Wiring: Follow standard 2-wire, 3-wire, or 4-wire RTD configurations as specified in the ABB S900 Technical Documentation to ensure proper lead-wire resistance compensation. Ensure cable shields are grounded correctly to block high-frequency electromagnetic interference.
