Isolated, Linearized Thermocouple Input 7B47
FEATURES
Interfaces, amplifies and filters input
voltages from a J, K, T, E, R, S, B or N-type thermocouple. Module provides a precision output of either +1 V to +5 V or 0 V to +10 V, linear with input temperature. All 7B47 series modules are mix-and-match and Hot Swappable.

PRODUCT OVERVIEW
The 7B Series of signal conditioners feature small size, low cost and a wide output
voltage range for a variety of applications including process control and factory-floor environments. The single-channel 7B modules accept inputs from a range of transducers and are fully rated over the extended -40oC to +85oC industrial temperature range. All 7B Series modules are rated for a nominal power supply input of +24 VDC; and, for maximum flexibility, they will accept supply
voltages in the +14 VDC to +35 VDC range. The input modules, with the exception of the 7B21, provide a high-level output
voltage that is factory configured for either the +1 V to +5 V or 0 V to +10 V range. The 7B21 is a unity gain, isolated input module with an input/output range of +10V. Output modules are available that provide either isolated process current or isolated bipolar
voltage output. Model 7B39 converts either a +1 V to +5 V input to a 4 to 20 mA output or a 0 V to +10 V input to a ...
