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

MODEL: WJM–1[1][2]–[3][4]
ORDERING INFORMATION
•Code number: WJM-1[1][2]-[3][4]
Same range availability as Output 1
Specify a code from below for each of [1] through [4].
(e.g. WJM-1A6-B/Q)
[3] POWER INPUT
AC Power
•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)
B: 100 V AC
C: 110 V AC
D: 115 V AC
F: 120 V AC
G: 200 V AC
H: 220 V AC
J: 240 V AC
Note: When the user requires a current and a voltage
output, specify the current to be the Output 1 which allows
a greater load.
DC Power
S: 12 V DC
R: 24 V DC
V: 48 V DC
