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.
