Analog Devices 5B37-S-05 Isolated Input Module

Analog Devices 5B37-S-05 Isolated Thermocouple Input Module is a single‑channel plug‑in signal conditioner that accepts S‑type thermocouple inputs and delivers an isolated 0–5 V output. As part of the 5B Series, it provides 1500 V rms continuous CMV isolation between the sensor side and the output, enabling galvanic isolation for temperature measurement in industrial control and data acquisition systems. The input stage is protected to 240 V rms at the screw terminals, offering resilience against wiring transients. The module interfaces, amplifies, and filters the thermocouple signal, achieving a calibrated accuracy of ±0.05% and a bandwidth suitable for typical thermocouple applications. The 5B37 family is designed to be hot‑swappable and mix‑and‑match with other 5B modules, allowing compact, modular I/O integration. The S‑05 designation indicates the S‑type thermocouple input with a 0–5 V isolated output, which can be read by voltage‑input DAQs or PLC analog inputs. Typical uses include high‑temperature process monitoring, laboratory temperature measurement, and industrial control where precise isolated sensing of Type S thermocouples is required. By consolidating sensing, isolation, and protective features in a single plug‑in unit, the 5B37‑S‑05 simplifies system design and reduces external component counts.
