Rack-mounted DCS Signal Conditioners 18-RACK

LINEARIZER

(field-programmable)

Functions & Features

• Accepting non-linear input and providing two linearized

outputs, proportional to the process variables

• Micro-processor based

• On-site calibration up to 16 points using a hand-held

programmer PU-2x

• Field-programmable input range

• Second channel output available at the front terminals

and at the Standard Rack connector

Typical Applications

• V-notch weir

• Gas analyzer

• Irregular-shaped tank level input for volume calculation

MODEL: 18JFX–[1]66–R

ORDERING INFORMATION

• Code number: 18JFX-[1]66-R

Specify a code from below for [1].
