Dual Output Plug-in Signal Conditioners W-UNIT

FILTER/LAG TRANSMITTER

(field-programmable)

Functions & Features

• Providing various filter functions which eliminate

unnecessary elements in the input signals

• Microprocessor based

• On-site calibration via hand-held programmer PU-2x

• Field-programmable input range

• Isolation up to 2000 V AC

• High-density mounting

Typical Applications

• Level control; eliminating drifts in the input signal caused

by pumps

MODEL: WJFT[1]–[2][3][4]–[5][6]

ORDERING INFORMATION

• Code number: WJFT[1]-[2][3][4]-[5][6]

Specify a code from below for each of [1] through [6].

(e.g. WJFT1-6A6-B/Q)

• Special input and output ranges (For codes U1, U2, U3, Z

& 0)

• Parameters (See "Functions" section)

Default setting will be used if not otherwise specified.

Use Ordering Information Sheet (No. ESU-1679) to specify

parameters.

• Specify the specification for option code /Q

(e.g. /C01/S01)

Note: When the user requires a current and a voltage

output, specify the current to be the Output 1 which allows

a greater load.
