HONEYWELL 8C-PCNT02

Description

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 eyes to important
status information.
• “Tilted” design allows for effective heat management within the cabinet enclosure. Since Series 8 allows for
a significant increase in cabinet density, an effective heat management system is critical for high system
availability.
• Input and output circuits are protected from shorts to alleviate the need for in- line fusing, reducing installation
and maintenance costs
Series 8 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 through cables from header board.
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 traditional rack based systems. 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 can be found in the Model Number Table.
I/O Module Functions
• TC/RTD (16pt) – Provides thermocouple (TC) and resistance temperature device (RTD) inputs.
• Analog Input – Single Ended (16pt) – The Analog Input Module supports analog inputs which are typically
4-20mA DC inputs for traditional devices, such as transmitters.
• Analog Input with HART – Single Ended (16pt) – The Analog
Input Module supports both 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.
• Analog Input with HART – Differential (16pt) – The Analog Input
Module supports Single Ended or Differential analog inputs, and
HART inputs.
• Analog Output (16pt) – The Analog Output Module supports
standard 4-20mA DC outputs.
• Analog Output with HART (16pt) – The Analog Output Module
supports both standard 4-20mA DC outputs and HART outputs.

Series 8 Controller and I/O Specification, S803-150-110 5
• Digital Input Sequence of Events (32pt) – Accepts 24VDC discrete signals as discrete inputs. The inputs
can be time tagged to support 1ms resolution Sequence of Events.
• Digital Input 24 VDC (32pt) – Digital input sensing for 24V signals
• Digital Input Pulse Accumulation (32pt) – Accepts 24VDC discrete signals as discrete inputs. The first
16 channels can be configured as Pulse accumulation to support Pulse Accumulation and frequency
measurement on per channel basis. Channels 17 – 32 can be configured as DI.
• Digital Output 24 VDC (32 pt) – Current sinking digital outputs. Outputs are electronically short-circuited
protected.
• DO Relay Extension Board (32 pt) – Digital output with NO or NC dry contacts. It can be used for low power
or high power applications.
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 mm2
stranded wire.
IOTA 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.
