CC-TAON11 C系列I/O模块

All Series C 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 C 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 available directly on the IOTA without any external cabling or redundancy control devices, by simply adding a second IOM to an IOTA.
• The Series C 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:
• Vertical mounting for more effective wiring since most field wiring applications require entry from the top or bottom of the systems cabinet.
• An “information circle” for a quick visual cue to draw the Maintenance Technician’s eye to important status information.
• “Tilted” design for effective heat management within the cabinet enclosure. Since Series C allows for a significant increase in cabinet density, an effective heat management system is critical for high systems availability.
• Input and output circuits are protected from shorts to alleviate the need for in-line fusing, reducing installation and maintenance costs.

Series C IOTAs combine multiple functions into a single piece of equipment:
• Single and redundant configurations.
• On-board termination of process signals.
• On-board signal conditioning.
• On-board connection to appropriate networks (FTE, I/O LINK).
• Field power distribution without external marshalling.
• IOM plugs into the IOTA and receives power from the IOTA.
• The IOTA receives its power from a 24 VDC bus that is part of the IOTA carrier – the IOTA is screwed into the bussed power.
