Selecting I/O Module

To organize an ADAM-5550KW Series control system, you need to
select I/O modules to interface the main unit with field devices or
processes that you have previously determined. There are several
things should be considered when you select the I/O modules.
What type of I/O signal is applied in your system?
How many I/O is required to your system?
How will you place the controller for concentrate the I/O points of
an entire process?
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 discrete & analog I/O module selection guidelines as below.
Choose this type of
I/O module:
Discrete input
module and block
I/O module
Discrete output
module and block
I/O module
Analog input module
Analog output
module
Table 2-2 Discrete and Analog I/O Selection Guidelines
Advantech provides 20 types of ADAM-5000 I/O modules for various
applications so far. The Figure 2-1 and Table 2-3 will help you to select
the ADAM-5000 I/O modules quickly and easily.

For these types of field devices
or operations (examples):
Selector switches, push buttons,
photoelectric eyes, limit switches,
circuit breakers, proximity
switches, level switches, motor
starter contacts, relay contacts,
thumbwheel switches
Alarms, control relays, fans, lights,
horns, valves, motor starters,
solenoids
Thermocouple signals, RTD
signals, temperature transducers,
pressure transducers, load cell
transducers, humidity transducers,
flow transducers, potentiometers.
Analog valves, actuators, chart
recorders, electric motor drives,
analog meters
Explanation:
Input modules sense ON/OFF
or OPENED/CLOSED signals.
Discrete signals can be either
AC or DC.
Output module signals
interface with ON/OFF or
OPENED/CLOSED devices.
Discrete signals can be either
AC or DC.
Convert continuous analog
signals into input values
Interpret output value to
analog signals (generally
through transducers) for field
devices.
