Space-saving Plug-in Signal Conditioners F-UNIT

POTENTIOMETER TRANSMITTER

(field-programmable)

Functions & Features

• Providing a DC output proportional to a potentiometer or

slidewire position input

• Microprocessor based

• Constant voltage excitation allows use with pots with total

resistances from 100 Ω – 10 kΩ without affecting accuracy

• 75 % zero/span adjustments with minimal interaction

• Linearization data programmable via hand-held

programmer PU-2x

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

• High-density mounting

Typical Applications

• Tank levels

• Positions: Compensating non-linear signal from the linking

mechanism of a position detector

MODEL: FJM–1[1]–[2][3]

ORDERING INFORMATION

• Code number: FJM-1[1]-[2][3]

Specify a code from below for each of [1] through [3].

(e.g. FJM-1A-L/Q)

• Linearization data (max. 16 points)

Use Ordering Information Sheet (No. ESU-1669) to specify

linearization data when the I/O signals are non-linear.

• Specify the specification for option code /Q

(e.g. /C01/S01)
