POTENTIOMETER TRANSMITTER
(field-programmable)

Functions & Features
• Providing 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 – 10kΩ without affecting accuracy
• 75 % zero/span adjustments with minimal interaction
• Linearization data programmable via hand-held programmer PU-2x
• Isolation up to 2000 V AC
• 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: JM–1[1]–[2][3]

ORDERING INFORMATION
• Code number: JM-1[1]-[2][3]
Specify a code from below for each of [1] through [3]. 
  (e.g. JM-1A-B/Q)
• Special output ranges (For codes Z & 0)
• 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)
