Product details

Overview

5B37-B-06 from Analog Devices is a single-channel isolated thermocouple input signal conditioner for Type B thermocouples (0°C to +1800°C), delivering a precision 0 V to +5 V isolated output with ±0.05% span accuracy, 1500 V_rms continuous isolation, and integrated cold-junction compensation. It is used in industrial temperature monitoring systems where high-temperature measurement, field-side overvoltage protection, and hot-swappable modularity are required.

For engineers reviewing the 5B37-B-06 datasheet, 5B37-B-06 pinout, 5B37-B-06 application, or 5B37-B-06 equivalent, key selection considerations include its Type B thermocouple range, 4 Hz bandwidth, chopper-stabilized amplifier drift (±1 µV/°C), 240 V_rms input terminal withstand rating, and compatibility with FM/CSA Class 1 Division 2 hazardous locations.

Technical Context

The 5B37-B-06 implements transformer-based galvanic isolation with proprietary modulation for linear signal recovery, featuring a fully floating differential input stage eliminating input grounding requirements. Its chopper-stabilized amplifier provides low-drift gain and laser-trimmed zero-scale offset subtraction for expanded-scale measurements.

Internal multi-pole low-pass filtering delivers 4 Hz –3 dB bandwidth, achieving 60 dB normal-mode rejection at 60 Hz and 160 dB common-mode rejection with 1 kΩ source imbalance. Cold-junction compensation uses an on-board sensor with ±0.25°C initial accuracy at +25°C and supports open-thermocouple detection via upscale output response.

Equivalent & Alternatives

The following parts are listed as comparable options for similar thermocouple signal conditioning applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADAM-4018-B	8-channel Ethernet-based module with built-in ADC; no transformer isolation; 1500 V_DC isolation via optocouplers only	Designed for networked distributed I/O; requires external power and Ethernet infrastructure	Select when remote monitoring over LAN is needed and transformer-level isolation is not mandatory
SCXI-1122	NI SCXI module with 16-bit resolution, software-configurable thermocouple types, but no field-side screw terminals or FM/CSA certification	Requires SCXI chassis and host PC; intended for lab/test environments, not industrial hazardous locations	Select for high-resolution benchtop validation where certification and rugged field terminals are unnecessary

Compared with ADAM-4018-B and SCXI-1122, the 5B37-B-06 uniquely combines certified hazardous-area suitability, transformer-based 1500 V_rms isolation, screw-terminal field wiring, and hot-swappable modularity-making it optimal for fixed industrial control cabinets requiring long-term reliability and compliance.

FAQ

What thermocouple type does the 5B37-B-06 support?

The 5B37-B-06 is factory-configured exclusively for Type B thermocouples, covering an input range of 0°C to +1800°C. It performs cold-junction compensation and linearization specific to Type B characteristics, and cannot be reconfigured for other thermocouple types without hardware modification or replacement.

Does the 5B37-B-06 require an external cold-junction sensor?

No-the 5B37-B-06 relies on internal cold-junction compensation when installed in a 5B Series backplane equipped with the AC1361 sensor (standard on all channels). No external CJC sensor is needed unless used standalone without a certified backplane, in which case accuracy degrades beyond ±0.75°C.

What is the maximum continuous voltage the 5B37-B-06 can withstand at its input terminals?

The 5B37-B-06 input screw terminals are rated for continuous operation at up to 240 V_rms without damage or performance degradation. This rating applies under normal operating conditions and ensures protection against common industrial overvoltage faults on the field side.

Can the 5B37-B-06 be hot-swapped in a live 5B Series backplane?

Yes-the 5B37-B-06 is fully hot-swappable per 5B Series specifications. It may be inserted or removed from any powered 5B backplane without interrupting field wiring, system power, or adjacent modules' operation, maintaining signal integrity and safety during maintenance.

What certifications apply to the 5B37-B-06 for hazardous locations?

The 5B37-B-06 carries Factory Mutual (FM) and Canadian Standards Association (CSA) approvals for Class 1, Division 2, Groups A, B, C, and D-certifying it as nonincendive for use where flammable gases may exist only under fault conditions, without requiring explosion-proof enclosures.
