MODEL: WJFX–[1][2][3]–[4][5]
ORDERING INFORMATION
• Code number: WJFX-[1][2][3]-[4][5]
Specify a code from below for each of [1] through [5].
(e.g. WJFX-6A6-B/Q)
• Special input and output ranges (For codes U1, U2, U3, Z & 0)
• Linearization data (max. 16 points)
Use Ordering Information Sheet (No. ESU-1669) to specify linearization data when the I/O signals are nonlinear.
• Specify the specification for option code /Q
(e.g. /C01/S01)
Note: When the user requires a current and a voltage output, specify the current to be the Output 1 which allows a greater load.
