Power Supply for Analog I/O Modules
Wiring Analog I/O Lines
When supplying power to the analog I/O modules, take the following considerations.
•
Use separate power supplies for the MicroSmart CPU module and END refresh type analog I/O modules. Power up the
analog I/O modules at least 1 second earlier than the CPU module. This is recommended to ensure correct operation of the
analog I/O control.
•
Use the same power supply for the MicroSmart CPU module and ladder refresh type analog I/O modules to suppress the
influence of noises.
After the CPU module has started to run, ladder refresh type analog input modules perform initialization for a maximum
of 5 seconds. During this period, the analog input data have an indefinite value. Design the user program to make sure that
the analog input data are read to the CPU module after the analog input operating status has changed to 0 (normal opera-
tion). For the analog input operating status, see page 4-13.
Separate the analog I/O lines, particularly resistance thermometer inputs, from motor lines as much as possible to suppress
the influence of noises.
