DC - DC ISOLATOR / CONVERTER
SEM1100
|
INTRODUCTION
The SEM1100
is an isolating converter that accepts most
common high level process signals (current and voltage), isolates them
electrically and physically, and converts them to another process
signal. It is also possible to have voltage and current outputs
simultaneously from a single input.
The isolator is available in AC and DC powered
versions, both generating loop excitation for input and output loops
at the same time.
Zero and span adjustment potentiometers are
conveniently situated on the front panel together with a power ON LED.
Configuration (factory set if specified) can easily be changed by
means of internal switches and the use of suitable equipment.
