Product details
Overview
5B47-J-02-NI from Analog Devices is an isolated, linearized thermocouple input signal conditioner for Type J thermocouples with input range –100°C to +300°C, 0 V to +5 V isolated output, ±0.5°C accuracy, and 1500 Vrms continuous input-to-output isolation-used in industrial temperature monitoring systems requiring cold-junction compensation and field-side overvoltage protection.
For engineers reviewing the 5B47-J-02-NI datasheet, 5B47-J-02-NI pinout, 5B47-J-02-NI application, or 5B47-J-02-NI equivalent, key selection considerations include its chopper-stabilized amplifier (±1 µV/°C input offset drift), 4 Hz bandwidth, 240 Vrms input terminal withstand rating, open-thermocouple upscale detection, and hot-swappable 5B Series compatibility.
Technical Context
The 5B47-J-02-NI implements transformer-based galvanic isolation with proprietary modulation/demodulation for linear signal transfer, combined with internal cold-junction compensation using a factory-mounted CJC sensor. Its differential, fully floating input eliminates need for input grounding.
Signal conditioning includes multi-pole low-pass filtering (–3 dB at 4 Hz), chopper-stabilized amplification, laser-trimmed zero-scale offset subtraction, and series output switching controlled by active-low enable. Output common must remain within ±3 V of power common.

Equivalent & Alternatives
The following parts are listed as comparable options for similar thermocouple signal conditioning applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5B47-J-01 | Same package, pinout, and architecture; narrower input range (0°C to +760°C) and lower accuracy (±1.1°C) | Used where only positive-temperature measurement is needed and ±1.1°C error is acceptable | Select 5B47-J-01 only if extended low-end range (–100°C) and tighter ±0.5°C accuracy are not required. |
| 5B47-J-03 | Same package and architecture; input range 0°C to +500°C; accuracy ±0.6°C | Optimized for mid-range industrial furnaces where sub-zero operation is unnecessary | Choose 5B47-J-03 when operating above 0°C only and slightly relaxed accuracy vs. 5B47-J-02-NI is acceptable. |
Compared with 5B47-J-01 and 5B47-J-03, the 5B47-J-02-NI uniquely supports –100°C start point with ±0.5°C accuracy-critical for cryogenic or ambient-compensated low-temperature processes where the other variants cannot operate or meet spec.

FAQ
What is the input temperature range supported by the 5B47-J-02-NI?
The 5B47-J-02-NI supports a Type J thermocouple input range of –100°C to +300°C (–148°F to +572°F). This range is factory-configured and linearized internally; output scales proportionally from 0 V to +5 V across the full span. Accuracy is specified as ±0.5°C at +25°C ambient, including cold-junction compensation error.
Does the 5B47-J-02-NI require external cold-junction compensation hardware?
No, the 5B47-J-02-NI includes internal cold-junction compensation using the AC1361 sensor mounted on compatible 5B Series backplanes. It achieves ±0.25°C initial accuracy at +25°C ambient, eliminating need for external CJC circuitry. The module automatically corrects for parasitic thermocouples formed at the input screw terminals.
Can the 5B47-J-02-NI be used in hazardous locations?
Yes, the 5B47-J-02-NI is certified by Factory Mutual (FM) and CSA for Class 1, Division 2, Groups A, B, C, and D-meaning it is approved for use where flammable gases may exist only under fault conditions. Its nonincendive design requires no special enclosures, making it suitable for oil & gas, chemical, and pharmaceutical process environments.
What is the isolation rating and overvoltage protection capability of the 5B47-J-02-NI?
The 5B47-J-02-NI provides 1500 Vrms continuous galvanic isolation between input and output circuits. Its input screw terminals withstand 240 Vrms continuously without damage, protecting downstream data acquisition or control circuitry from field-side overvoltage faults-a critical feature in electrically noisy industrial plants.
How does the 5B47-J-02-NI indicate an open thermocouple fault?
The 5B47-J-02-NI generates an upscale output (>+5 V) within 10 seconds of detecting an open thermocouple circuit. This behavior is automatic and requires no external components. For downscale indication instead, a 20 MΩ, 0.25 W resistor must be connected across screw terminals 1 (–EXC) and 3 (HI).
