Precautions When Using The Melsec-Ans Series Programmable Controller - Mitsubishi Electric MELSEC-Q Series User Manual

3.2.2 Precautions when using the MELSEC-AnS series
programmable controller
Module selection
(1) Power module
For a power module with rated input voltage of 100/200 VAC,
select a model in which the internal part between the first order and
second order is intensively insulated, because it generates
hazardous voltage (voltage of 42.4 V or more at the peak) area.
For a power module with 24 VDC rated input, a conventional model can
be used.
(2) I/O module
For I/O module with rated input voltage of 100/200 VAC, select a
model in which the internal area between the first order and
second order is intensively insulated, because it has hazardous
voltage area.
For I/O module with 24 VDC rated input, a conventional model can
be used.
(3) CPU module, memory card, base unit
Conventional models can be used for these modules, because
they only have a 5 VDC circuit inside.
(4) Special function module
Conventional models can be used for the special function modules
including analog module, network module, and positioning module,
because the rated voltage is 24 VDC or smaller.
(5) Display device
Use the CE marked product.
