Red Lion CTD - Manual

z THREE JUMPER SELECTABLE INPUT RANGES
z OUTPUT IS MAGNETICALLY ISOLATED FROM THE INPUT
z INTERNAL POWER REGULATION
z 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.
