Introduction
Classic I/O is a modular subsystem that offers
flexibility during installation. It’s designed to be
installed in the field, near your devices. Classic I/O is
equipped with function and field wiring protection
keys to ensure that the correct I/O card is always
plugged into the corresponding terminal block.
Modularity, protection keys, and plug and play
capabilities make DeltaV Classic I/O a smart choice
for your process control system.
The Classic I/O subsystem includes:
✔ I/O interface carrier (a DIN rail surface mounted)
on which all I/O related components are
installed.
✔ Bulk AC to 24 VDC power supply for field
devices.
✔ An I/O interface consisting of an I/O card and an
I/O terminal block.
✔ A variety of analog and discrete I/O cards
enclosed in a common form factor that easily
plugs into the I/O interface carrier.
✔ A variety of I/O terminal blocks mounted on the
I/O interface carrier that can be pre-wired before
I/O card installation.
