Isolated Process Current Input - Analog Devices
Description
Isolated Process Current Input with Loop Power 7B35
FEATURES
Single-channel signal conditioning current input module that interfaces with two-wire transmitters.
Module provides a precision output of either +1 V to +5 V or +2 V to +10 V, linear with temperature.
Features a isolated 24 VDC loop supply for driving the transmitter.
All 7B35 series modules are mix-and-match and Hot Swappable.
