Quantum I/O modules are electrical signal converters that convert signals to and from field devices to a signal level and format that can be processed by the CPU.
I/O modules are optically isolated to the bus. I/O modules are also software configurable.
Typical field devices include:
-
limit switches
-
proximity switches
-
temperature sensors
-
solenoids
-
valve actuators
