(field-programmable)
• 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
the users manual for the PC configurator for applicable
cable types.
Functions & Features
• Segment linearization characteristics are freely
configurable via programming unit
• Module can be retracted without removing wiring for an
insulation test
• Optional power switch

ORDERING INFORMATION
• Code number: 18KJM-166-R[1]
Isolation: Input to output 1 to output 2 to power
Linearization: 16 points max. within the range of -15.00 –
+115.00 % input or output; represented as percentage of
full-scale
Specify a code from below for [1].
(e.g. 18KJM-166-R/S)
• Linearization data (max. 16 points)
Use Ordering Information Sheet (No. ESU-1669) to specify
linearization data when the I/O signals are non-linear.
Adjustments: Programming Unit (model: PU-2x);
linearization data (Unused resistance of the potentiometer's
total resistance can be programmed with the linearization
table.), zero and span, simulating output, etc.
(Refer to the users manual of JXCON for the adjustments
configurable with JXCON.)
