MODEL: WJS–1[1][2]–[3][4]
ORDERING INFORMATION
•Code number: WJS-1[1][2]-[3][4]
Specify a code from below for each of [1] through [4].
(e.g. WJS-1AA-B/Q)
• Input range (e.g. 270°)
• 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 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.
