HONEYWELL CC-MCAR02

Description

HONEYWELL CC-MCAR02Features
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.
Experion Series-C I/O Specification, EP03-490-520 5
Version 1.5 Honeywell Proprietary Dec 2021
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.
3. 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.
3.1. 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.
• Digital Input 24 VDC (32pt) – Digital input sensing for 24V signals. Two versions are available.
• Digital Input High Voltage (32pt) – Digital input sensing for 110 VAC, 220 VAC, 125VDC.
• Digital Output 24 VDC (32 pt) – Current sourcing digital outputs. Outputs are electronically short-circuit protected.
Two versions are available.
• Relay Digital Output (32 pt) – Digital output with NO or NC dry contacts. Can be used for low power or high power
applications.
• Temperature Multiplexer (64 pt) – Provides thermocouple (TC) and resistance temperature device (RTD) inputs.
The Multiplexer supports up to four, field proven PMIO FTAs.
• Temperature Multiplexer (64 pt) – Provides thermocouple (TC) and resistance temperature device (RTD) inputs.
The Multiplexer supports up to four, field proven PMIO FTAs
• Pulse Input (8pt) – Provide linear counting, PV generation, and Quaduature Input for Custody Transfer
• Universal Input Output (32 pt) – Supports 32 channels of user configurable IO. Choices available – analog input,
analog output, digital input, and digital output.
