Dielectric withstand voltage test and insulation resistance test
Perform dielectric withstand voltage test and insulation resistance test at the following voltages between each terminal and
the CPU module ground terminal.
■CPU module, I/O module
Between terminals
Between power supply terminal (AC
power supply) and ground terminal
Between power supply terminal (DC
power supply) and ground terminal
Between 24VDC service power supply
connected to input terminal (24VDC)
and ground terminal
Between input terminal (24VDC) and
ground terminal
Between output terminal (relay) and
ground terminal
Between output terminal (transistor) and
ground terminal
■Expansion board, expansion adapter
Between terminals
Between terminal of expansion board
and ground terminal
Between terminal of expansion adapter
and ground terminal
*1 Since the expansion board and CPU module are not insulated, it is not allowed to perform the dielectric withstand voltage test and
insulation resistance test between them.
For dielectric withstand voltage test and insulation resistance test of each product, refer to manuals of each product.
■Intelligent function module, FX5 safety extension module
For information concerning dielectric withstand voltage and insulation resistance of the following modules, refer to the user's
manuals of each module.
• Intelligent function module
• FX5 safety extension module
