OVERVIEW

Emerson has developed a DIN-rail mounted power supply that includes four modular fanless power systems to provide reliable and stable power to Ovation™ controllers and I/O modules.

The Ovation controller power supply systems are configured in redundant configurations, each with a separate external wide-range AC and/or DC input feed.

Dual diode auction 24 VDC outputs are used to power each controller chassis and associated I/O modules, as well as to power loop and contact wetting for the I/O modules.

A 48 VDC auxiliary power supply is available for loop and contact wetting if required.

Two separate output schemes are available:

24 VDC / 10 A / 240 W main power and 24 VDC / 10 A / 240 W auxiliary power.

24 VDC / 20 A / 480 W main power supply and 24 VDC / 20 A / 480 W auxiliary power supply.

Benefits

Benefits of Ovation power solutions include

Separate primary and auxiliary power supplies are easy to replace

No cooling fan required, greatly reducing the risk of failure

Diode auction feed ensures continuous power

New design improves efficiency, reduces heat generation and extends equipment life expectancy

Dual input (AC and DC) capability reduces spare parts

Hot-swappable power supplies enable in-line replacement

10 Amp Power Solutions

10 Amp power supply options include

Redundant Power Configuration (Primary and Auxiliary) includes separate 10 Amp Primary and Auxiliary power supplies supporting multiple input voltages (85-264 VAC @ 43-67 Hz or 90-375 VDC) with 240 W output power.

Features and Applications

The Model 1066 Fieldbus Transmitter supports continuous measurement of one liquid analysis input.

It is designed for easy internal access and wiring connections.

Analytical inputs: pH and ORP sensors with dcs-sis.com or without Rosemount Analytical preamplifiers, and Rosemount Analytical smart pH sensors.

Large Display: High-contrast LCD displays real-time measurement readings in large numbers and up to four additional variables or diagnostic parameters.

Digital Communications: Fieldbus ITK 6 Menus: Menu screens for calibration and programming are simple and intuitive. Plain language prompts and “help” screens guide the user through the steps.

All menu screens are available in eight languages. Real-time process values are displayed during programming and calibration.

Troubleshooting and Warning Help Screens: Troubleshooting and warning information is included in the Help screens to provide the user with helpful troubleshooting tips. These screen instructions are intuitive and easy to use.

Diagnostics: The transmitter continuously monitors itself and the sensors for problems. On-screen display banners alert technicians to faults and/or warning conditions.

Languages: Emerson extends its global reach by offering eight languages: English, French, German, Italian, Spanish, Portuguese, Chinese, and Russian.

Input Damping: Automatically enabled to suppress noisy process readings.

Smart Enable pH: Rosemount Analytical SMART pH feature eliminates the need for field calibration of pH probes by automatically uploading calibration data and history.

Automatic Temperature Compensation: pH measurements require temperature compensation. the 1066 will automatically recognize the sensor’s built-in Pt100 or Pt1000 RTD, or the temperature of an on-bus temperature measurement can be linked to the 1066 and used for temperature compensation.

Sensor Wiring

Overview

Connect the correct sensor leads to the main board according to the lead locations labeled directly on the main board.

Rosemount Analytical SMART pH sensors can be connected to the 1066 using either the integrated cable SMART sensor or a compatible VP8 pH cable.

After completing the wiring of the sensor leads, carefully route the excess sensor cable through the cable gland.

Separate the sensor and output signal wiring from the loop power wiring. Do not place the sensor and power wires in the same conduit or near a cable bridge.

VersaPoint I/O

The VersaPoint™ Distributed I/O System offers optimal compactness and flexibility while allowing users to install the right amount of I/O for each application.

Allows users to install the right amount of I/O for each application.

VersaPoint adheres to open communication standards, including Ethernet, Profibus-DP™, and DeviceNet™, for easy connection to a wide range of PLCs, DCSs, and PC-based control systems.

It is suitable for packaging and material handling applications as well as monitoring and data acquisition.

Superior Flexibility

VersaPoint’s modular structure allows it to be easily adapted to a wide range of applications. It accommodates a range of discrete and analog I/O modules, from 1-point to 16-point densities.

VersaPoint also supports a wide range of specialized modules, from RTD and thermocouple inputs to positioning and counting modules, virtually combining intelligent automation with the simplicity of endpoint technology.

Compact size

VersaPoint saves valuable control panel space by eliminating the need to plug in terminals.

Its compact and versatile design saves up to 50% of space compared to conventional systems.

Reduced Installation Time

Installing VersaPoint couldn’t be quicker: I/O modules can be quickly and securely fastened to the DIN rail.

Thanks to the integrated I/O terminals and internal power bus, VersaPoint reduces wiring by up to 80%.

Cost-effective solution

Fast installation, reduced cabling, and more efficient use of cabinet space all make VersaPoint a great value.

Cost savings continue during operation. Extensive built-in diagnostics make identifying faults routine, maximizing uptime.

The Traditional I/O subsystem includes:

I/O interface carrier (a DIN rail surface mounted) on which all I/O related components are installed.

Bulk AC to 24V DC power supply for field devices.

An I/O interface consisting of an I/O card and an I/O terminal block.

A variety of analog and discrete I/O cards enclosed  in a common form factor that easily plugs into the  I/O interface carrier.

A variety of I/O terminal blocks mounted on the I/O interface carrier that can be pre-wired before I/O card installation.

I/O Cards

A variety of analog and discrete I/O cards are available to meet your specific requirements.

The following cards support simplex or redundant installation:

AI 4-20 mA HART 8 channels

AO-4-20 mA HART 8 channels

DI, 24V DC Dry Contact, 8 channels

DO 24V DC High-Side, 8 channels

AI (Plus) 4-20 mA HART, 16 channels

AO (Plus) 4-20 mA HART, 16 channels

DI (Plus) 24V DC, Dry Contact, 32 channels

DO (Plus) 24V DC, High-Side, 32 channels

Decreases capital equipment costs

Full system modularity: The Traditional I/O subsystem was designed with your investment in mind. All components are fully modular and may be installable under power. You add I/O interface carriers and I/O interfaces in groups of 4. 8. 16.or 32 channels as you need them. The modular design enables you to purchase the exact amount of I/O cards, 8-wide or 4-wide carriers, power/ controllers, and 2-wide carriers you need and add more DeltaV I/O as your system grows.

Reduced system footprint: The DeltaV system’s state-of-the- art form factor design of the I/O components enables you to mount the I/O interface carrier in a junction box in the field  so you significantly reduce the footprint of your equipment  and increase valuable control room space for other uses.

Installation: Save on wiring expenses by installing Classic Instrumentation in the field, near the actual field devices.

Mounting the controller with the I/O further reduces your wiring expenditures by eliminating the need for long runs  of multi-cores. The integrated design of the Traditional I/O subsystem can eliminate the need for marshalling panels.

This saves you even more in your total capital costs.

The provision of in-line fuses and bussed power saves  on installation costs compared with external fuses and  power distribution.
