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)
[3] POWER INPUT
AC Power
• Input range (e.g. 270°)
B: 100 V AC
• 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

* The output increases when the self-synch rotates clockwise. For changing
the operation to counterclockwise, replace the connection of the S2 and S3.
**Be sure that the polarity of the power input to the WJS matches to the self-
synch input polarity. When the connetion is reversed, the WJS output will be
shifted by 180°.
