3B47 - Isolated / Linearized / Thermocouple Input

Datasheet Summary

Description

The 3B47 is a single-channel isolated thermocouple signalconditioning module which interfaces, amplifies, isolates, protects, linearizes and filters analog input voltages from a J, K, T, E, R, S or B-type thermocouple.

Features

Interfaces, amplifies, filters, isolates, & linearizes analog input voltages from a J, K, T, E, R, S or B-type thermocouple Thermocouple input signal is internally linearized High accuracy internal cold junction compensation. Module provides +1500 V peak of galvanic transformerbased isolation with a common mode rejection (CMR) of 160 dB @ 50/60 Hz and a normal mode rejection (NMR) of 60 dB @ 50/60 Hz. All 3B47 series modules are mix-and-match and Hot Swappable.
