Honeywell Experion Series-C I/O Specification EP03-490-520

Product Introduction Summary 1.1. Overview This document provides technical information to configure the Experion® Series C I/O and the C300 Controller, released starting with Experion R300. 1.2. Scope The following Series C I/O items are included in this document. 

 • Digital Input 24 VDC   

• Digital Input 110 VAC / 125VDC 

 • Digital Input 220 VAC 

 • Digital Output (24 VDC bussed)   

• Digital Output Relay 

 • High Level Analog Input with HART   

• High Level Analog Input without HART 1.3. Definitions 

 • Analog Output with HART   

• Analog Output without HART 

 • Low Level Multiplexer – RTD & TC 

 • Low Level Input – RTD & TC 

 • Pulse Input 

 • Universal Input Output 

 • Input Output Termination Assembly (IOTA): An assembly that holds the IOM and the connections for field wiring,   

• Input Output Module (IOM): A device that contains most of the electronics required to perform a specific I/O function. The IOM plugs onto the IOTA. 2. Features 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.

Series C I/O Sizing 

In virtually all configurations, the C300 controller and Series C I/O provides useful, maintainable process equipment connections in a smaller footprint than existing competitors and Honeywell equivalent products. Installing Series C 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.

I/O Module Functions 

 • High Level Analog Input /HART Input Module (16pt) – The High Level Analog Input Module supports both high level analog and HART inputs. Analog inputs are typically 4-20mA DC for both traditional and HART devices. HART data can be used for status and configuration. HART data, such as the secondary and tertiary variables, can also be used as process control variables. Two versions are available. • High Level Analog Input w/o HART (16pt) - The High Level Analog Input Module supports high level analog inputs Analog inputs are typically 4-20mA DC for traditional devices. 

 • Analog Output/HART Output Module (16pt) – The Analog Output Module supports both standard 4-20mA DC outputs and HART transmitter outputs. Two versions are available. 

 • Analog Output w/o HART (16pt) – The Analog Output Module supports standard 4-20mA DC outputs.
