The 7B37 is a thermocouple input module from Analog Devices. This model has small size, low cost and a wide output voltage range. It can be widely used in process control and factory-floor environments. The 7B module supports inputs from a range of transducers and is fully rated over the extended -40oC to +85oC industrial temperature range.
The 7B37 is a single‑channel, isolated signal‑conditioning module that accepts J, K, T, E, R, S or B‑type thermocouples and provides a precision voltage output of +1 V‑to‑+5 V or 0 V‑to‑+10 V. It offers high‑accuracy cold‑junction compensation, up to 1500 V rms isolation and a common‑mode rejection of 160 dB.
The module operates from a +14 VDC‑to‑+35 VDC supply (nominal +24 VDC), works in temperatures from –40 °C to +85 °C, and is hot‑swappable in a 19‑inch rack‑mount backplane. Mechanical dimensions are 1.663" × 2.11" × 0.563" and it weighs 60 g.
