Features

Series 8 features an innovative design that supports enhanced heat management. This unique look provides a significant
reduction in overall size for the equivalent function.
Both Series 8 IOM and IOTA are available in Coated and Uncoated variants. The term 'Coated' stands for hardware with
conformal coating material applied to electronic circuitry for protection against moisture, dust, chemicals, and temperature
extremes. Coated IOM and IOTA are recommended when electronics must withstand harsh environments and need to have
added protection.
For a quick reference, all the Series 8 Honeywell models starting with 8C denotes 'with Conformal Coating' and the models
starting with '8U' denotes non-conformal coated hardware.
The unique features of the Series 8 I/O include:

I/O Module and field terminations are combined in the same area. The I/O Module is plugged into
the IOTA to eliminate the need for a separate chassis to hold the electronics assemblies

Two level "detachable" terminals for landing the field wiring in the enclosure, providing easier plant
installation and maintenance

Field power can be supplied through the IOTA, with no need for extra power supplies and the
associated craft wired marshalling

Redundancy is available directly on the IOTA without any external cabling or redundancy control
devices, by simply adding a second IOM to an IOTA

The innovative styling is one of its unique features. This styling includes features to facilitate the
effective use of control hardware in a systems environment. These features include:
