Product details
Overview
5B47-J-01-MB from Analog Devices is a single-channel, isolated, linearized thermocouple input signal conditioner for Type J thermocouples (0°C to +760°C), delivering a precision 0 V to +5 V output with ±1.1°C accuracy, 1500 Vrms input-to-output isolation, and 4 Hz bandwidth. It performs cold-junction compensation, chopper-stabilized amplification, multi-pole filtering, and open-thermocouple detection in industrial measurement systems.
For engineers reviewing the 5B47-J-01-MB datasheet, 5B47-J-01-MB pinout, 5B47-J-01-MB application, or 5B47-J-01-MB equivalent, key selection criteria include thermocouple type support, linearization accuracy, isolation rating, CJC performance, and hot-swappable 5B-series compatibility with standard backplanes.
Technical Context
The 5B47-J-01-MB implements transformer-based signal isolation with proprietary modulation for stable linear transfer, paired with chopper-stabilized input amplification (±1 µV/°C input offset drift) and internal cold-junction compensation using an on-board sensor. Its differential field-side input is fully floating, eliminating ground-loop constraints.
It integrates 4 Hz multi-pole low-pass filtering (60 dB normal-mode rejection at 60 Hz), 160 dB common-mode rejection at 50/60 Hz with 1 kΩ source imbalance, and active open-thermocouple detection with upscale fail-safe response (10 s timeout). Output enable control accepts TTL-compatible logic levels and drives a 50 Ω buffered voltage source.

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-02 | Narrower input range (–100°C to +300°C); higher accuracy (±0.5°C) | Better suited for low-temperature precision applications (e.g., environmental chambers) | Select when tighter accuracy over limited range outweighs extended high-temp coverage |

FAQ
What thermocouple types does the 5B47-J-01-MB support?
The 5B47-J-01-MB is configured exclusively for Type J thermocouples, covering the 0°C to +760°C range. It performs internal linearization and cold-junction compensation optimized for Type J characteristics. Other thermocouple types (e.g., K, T, S) require distinct models such as 5B47-K-05 or 5B47-S-10 - the 5B47-J-01-MB does not support them.
Does the 5B47-J-01-MB require external cold-junction compensation?
No. The 5B47-J-01-MB includes an integrated cold-junction compensation (CJC) sensor with ±0.25°C accuracy at +25°C ambient. It uses the AC1361 CJC sensor built into compatible 5B-series backplanes, eliminating need for external hardware or software compensation - the 5B47-J-01-MB delivers fully compensated output directly.
What is the isolation rating and safety certification of the 5B47-J-01-MB?
The 5B47-J-01-MB provides 1500 Vrms continuous input-to-output isolation and is certified by Factory Mutual (FM) and CSA for Class 1, Division 2, Groups A, B, C, and D hazardous locations. It meets ANSI/IEEE C37.90.1 transient immunity and EN50082-1 EMC standards - no additional barriers or enclosures are required for compliant installation.
Can the 5B47-J-01-MB be hot-swapped in a live 5B-series backplane?
Yes. The 5B47-J-01-MB is fully hot-swappable: it can be inserted or removed from any powered 5B-series backplane without disrupting field wiring, system power, or adjacent modules. This capability relies on its standardized pin-out, zero-insertion-force design, and internal protection circuitry - confirmed in the 5B47-J-01-MB functional description and user manual.
What output voltage range and load drive capability does the 5B47-J-01-MB provide?
The 5B47-J-01-MB delivers a precision 0 V to +5 V output into loads ≥50 kΩ, with a 50 Ω output impedance and short-circuit protection. Its buffered output maintains linearity and low noise even with capacitive loads up to 2000 pF, and output selection time is 6 µs - ensuring compatibility with fast-scanning DAQ systems and PLC analog inputs.
