Power Supply for PID Modules
When supplying power to the PID modules, take the following into consideration.
Using the same power supply for the MicroSmart CPU and the PID module is recommended to suppress the
influence of noise. If the same power source is used for the PID module and MicroSmart CPU module, after the
MicroSmart CPU is started to run, the PID module performs initialization for a maximum of 5 seconds. During
this period, each parameter has an indefinite value. Design the user program to make sure that each parameter
is referred in the CPU module after the PID module operating status is changed to 0001h (Normal operation).
Wiring of Power Line and I/O Lines for the PID Module
Separate the I/O lines, particularly resistance thermometers, from the power line as much as possible to
suppress the influence of noise.
Fuse (50V-1.2A)
Separate the I/O lines
from the power line
as much as possible.
