MODEL: WJPA–[1][2][3]–[4][5]
ORDERING INFORMATION
• Code number: WJPA-[1][2][3]-[4][5]
Specify a code from below for each of [1] through [5].
(e.g. WJPA-2AA-B/Q)
• Frequency range (e.g. 0 – 152.3 Hz)
Same range availability as Output 1
• Special output ranges (For codes Z & 0)
• Linearization data (max. 16 points)
Use Ordering Information Sheet (No. ESU-1673) to specify
linearization data when the I/O signals are non-linear.
• Specify the specification for option code /Q
(e.g. /C01/S01)
Note 1: When the user requires a current and a voltage
output, specify the current to be the Output 1 which allows
a greater load.
Note 2: Consult factory on applications with a sensor
handling periodically (& quickly) changing frequency (e.g.
