HONEYWELL Series 8 I/O Hardware

HONEYWELL Series 8 I/O Hardware

DESCRIPTION

Series 8 features an innovative design that supports enhanced heat management. This unique look provides a significant reduction in overall size for the equivalent function. Both Series 8 IOM and IOTA are available with Conformal Coated feature. The term ‘Coated’ stands for hardware with conformal coating material applied to electronic circuitry for protection against moisture, dust, chemicals, and temperature extremes. Coated IOM and IOTA are recommended when electronics must withstand harsh environments and need to have added protection.

FEATURES

The unique features of the 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 can be 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 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: 

o Vertical mounting for more effective wiring since most field wiring applications require entry from the top or bottom of the systems cabinet 

o An “information circle” for a quick visual cue to draw the Maintenance Technician’s eye to important status information 

o “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 

o 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:

o Single and redundant configurations 

o On-board termination of process signals 

o On-board signal conditioning 

o On-board connection to appropriate networks (FTE, I/O LINK) 

o Field power distribution without external marshalling 

o IOM plugs into the IOTA and receives power from the IOTA 

o The IOTA receives its power through cables from header board

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 Single ended and Differential type 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. 

• 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 

• 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 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 (32pt) – Current sinking digital outputs. Outputs are electronically short-circuit protected. 

• DO Relay Extension Board (32pt) – Digital output with NO or NC dry contacts. It can be used for low power or high power applications. 

• Low Level Analog Input – RTD & TC (16pt) – Provides thermocouple (TC) and resistance temperature device (RTD) inputs.
