Series 8 I/O Sizing; Series 8 Field Connections; I/O Module Sizes - Honeywell Experion 8 Series Technical Information

Series 8 Controller and I/O Specification, S803-150-500

Series 8 I/O Sizing

In virtually all configurations, the C300 controller and Series 8 I/O provides useful, maintainable process equipment
connections in a smaller footprint than existing competitors and Honeywell equivalent products. Installing Series 8 I/O
modules contributes to overall total installed cost savings.
IOTA sizes vary based on the application. In general, an analog module has 16 points and resides on a 6 inch
(152mm) IOTA for non-redundant applications and a 12 inch (304mm) IOTA for redundant applications. A discrete
module has 32 points and resides on a 9-inch (228mm) IOTA for non-redundant applications and a 12 inch (304mm)
IOTA for redundant applications. Specific information on the size of a particular module is described in the Model
Number Table.

Series 8 Field connections

Series 8 Field connections use a standard modular connector. The connector modularity allows for removal and insertion of
the field wiring. This significantly reduces installation and maintenance procedures and can assist in field check out. Series 8
field connectors accept up to 12 AWG / 2.5 mm

I/O Module Sizes

IOTA Sizing is nominal (6in = 152mm, 9in =228mm, 12in =304mm). I/O modules are associated with their respective IOTAs
in the table below. The I/O Module is supported by one or more IOTAs. Below section also provides an overview of various
available IO modules, IOTA, IOTA size and redundancy features for Coated and Uncoated modules under separate tables.
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.
As 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.
