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.

SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in the 

literature or on equipment must be observed to ensure personal safety and to 

prevent damage to either the instrument or equipment connected to it. If 

equipment is used in a manner not specified by the manufacturer, the protection 

provided by the equipment may be impaired.

Do not use this unit to directly command motors, valves, or other actuators
