Chapter 2
Selecting Your Hardware Components
2-1 Selecting I/O Module
To organize an ADAM-5000/TCP Series data acquisition & control
system, you need to select I/O modules to interface the main unit with
field de- vices or processes that you have previously determined. There
are sev- eral things should be considered when you select the I/O
modules. What type of I/O signal is applied in your system? How much
I/O is required to your system? How will you place the main unit for
concentrate the I/O points of an entire process.
How many ADAM-5000/TCP Series main units are required for
distributed I/O points arrangement.
What is the required voltage range for each I/O module? What
isolation environment is required for each I/O module? What are
the noise and distance limitations for each I/O module? Refer to
table 2-1 I/O as module selection guidelines
