MODEL CTD - DC CURRENT TRANSDUCER
 THREE JUMPER SELECTABLE INPUT RANGES
 OUTPUT IS MAGNETICALLY ISOLATED FROM THE INPUT
 INTERNAL POWER REGULATION
 SPLIT-CORE CASE FOR EASY INSTALLATION

GENERAL DESCRIPTION

CTD transducer combines a Hall Effect sensor and a signal conditioner into a
single package. This provides higher accuracy, lower wiring costs, easier
Installation and saves valuable panel space. The CTD has jumper selectable
current input ranges and industry standard 4-20 mA output with a split-core case.
CAUTION: Read complete
instructions prior to installation
and operation of the unit.
WARNING - EXPLOSION HAZARD - DISCONNECT POWER
AND ENSURE THE AREA IS KNOWN TO BE NON-HAZARDOUS
