ORDERING INFORMATION
• Code number: 18JDL-A[1]66-R
RELATED PRODUCTS
• Programming Unit (model: PU-2x)
Specify a code from below for [1].
(e.g. 18JDL-A366-R)
• PC configurator software (model: JXCON)
Downloadable at M-System’s web site.
A dedicated cable is required to connect the module to the
PC. Please refer to the internet software download site or

specified.
No linearization data will be programmed if you don't
specify type of linearization and required data.
• Linearization data
Code 1 segment data: Use Ordering Information Sheet (No.
ESU-1669) to specify linearization data.
Code 3 T/C, Code 4 RTD: Specify input sensor type and
temperature range.
