Functions & Features
R: 24 V DC
• Providing a DC output proportional to a potentiometer or
slidewire position input
(Operational voltage range 24 V ±10 %, ripple 10 %p-p max.)
• 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

ORDERING INFORMATION
• Code number: HJM-1[1]-R[2]
Housing material: Flame-resistant resin (black)
Isolation: Input to output to power
Specify a code from below for each of [1] and [2].
(e.g. HJM-1A-R/Q)
Linearization: 16 points max. within the range of -15.00 –
+115.00 % input or output; represented as percentage of
full-scale
• 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)
