Features All Series 8 components feature an innovative design that supports enhanced heat management. This unique look provides a significant reduction in overall size for the equivalent function. The unique features of 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 is supplied through the IOTA, with no need for extra power supplies and the associated craft wired marshalling. • Redundancy is accomplished directly on the IOTA without any external cabling or redundancy control devices, by simply adding a second IOM to an IOTA • For both IOM and IOTA, coated (module numbers starting with 8C) and uncoated (module numbers starting with 8U) options are provided. Conformal coating material is applied to electronic circuitry to act as protection against moisture, dust, chemicals, and temperature extremes. Coated IOM and IOTA are recommended when electronics must withstand harsh environments and added protection is necessary. The Series 8 inherits the innovative styling of Series C. This styling includes features to facilitate the effective use of control hardware in a systems environment. These features include: • Vertical mounting allows for more effective wiring since most field wiring applications require entry from the top or bottom of the systems cabinet. • An “information circle” allows for a quick visual cue to draw the Maintenance Technician’s eye to important status information.
