Rack-mounted DCS Signal Conditioners 18K-RACK

CURRENT LOOP SUPPLY

(linearizing; field-programmable)

Functions & Features

• 2-wire transmitter circuit with short-circuit protection

• Applicable to smart transmitters

• Segment linearization, square root extraction and

temperature linearization are freely configurable via

programming unit (model: PU-2x)

• Can also be used as a 4 - 20 mA DC linearizer

• Module can be retracted without removing wiring for an

insulation test

• Optional power switch

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: 18KJDL–A[1]66–R[2]

ORDERING INFORMATION

• Code number: 18KJDL-A[1]66-R[2]

Specify a code from below for each [1] and [2].

(e.g. 18KJDL-A366-R/S)

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.
