POWERED ISOLATING CONVERTOR SEM1100 10 YEAR WARRANTY HIGH ACCURACY 0.05 % POWERS BOTH LOOPS DRIVES CURRENT INTO 1K 3 PORT GALVANIC ISOLATION DIN RAIL OR SURFACE MOUNT SELECTABLE INPUT AND OUTPUT USER CONFIGURABLE INTRODUCTION The SEM1100 is a powered isolating converter that accepts most common high level process signals (current and voltage), isolates them electrically and physically, and converts them to any other 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.
