Rack-mounted DCS Signal Conditioners 18-RACK

CURRENT LOOP SUPPLY

(linearizing; field-programmable)

Functions & Features

• Powering a 4 – 20 mA DC current loop

• Microprocessor based

• Shortcircuit protection

• Applicable to smart transmitters

• Field-programmable linearization data

• Loop testing via hand-held programmer PU-2x

• Usable as Linearizer for 4 – 20 mA DC signals

• Second channel output available at the front terminals

and at the Standard Rack connector

Typical Applications

• Various 2-wire transmitters

• Providing isolation and linearization for a 2-wire

temperature transmitter

• Linearizing weir flowmeter output to provide a linear-to-

volume signal

MODEL: 18JDL–A[1]66–R

ORDERING INFORMATION

• Code number: 18JDL-A[1]66-R

Specify a code from below for [1].

(e.g. 18JDL-A366-R)

Default setting (table next) will be used if not otherwise

specified.

No linearization data will be programmed if you don't

specify type of linearization and required data.

• Linearization data

Code 1 segment data: Use Ordering Information Sheet (No.

ESU-1669) to specify linearization data.

Code 3 T/C, Code 4 RTD: Specify input sensor type and

temperature range.
