Overview
Isolated Voltage Input 7B31 FEATURES Interfaces, amplifies, and filters unipolar and bipolar voltage inputs.
Module provides a precision output of either +1 V to +5 V or 0 V to +10 V, linear with temperature.
Rated to operate with a nominal +24 VDC supply.
All 7B31 series modules are mix-and-match and Hot Swappable.
