Woodward 505DR Dual Redundant Turbine Controller

Description

Like the MicroNet Plus, the 505XT system designates one controller

as the System Controller (Syscon), actively controlling the fan.

The second device is configured as a backup.

The system automatically evaluates the health of the Syscon and initiates a fast switchover in the

event of a failure.

Switchover can also be initiated manually. The system closely synchronises

the Syscon’s software status and memory with the backup,

ensuring that the control output remains stable and does not affect turbine operation (a true ‘bufferless’

switchover).

If the optional HMI version is selected, the display and keypad are redundant

(input from either keypad will command Syscon, and the display can be independently selected to show

different screens.

For example, one screen can display speed and speed settings, and another can display a steam map.

Woodward’s optional RemoteView programme allows remote monitoring from any networked PC.

The programme can be used either with the rear panel mounted version (as the main HMI)

or as an additional remote monitor to the HMI version.

The optional FTM (Field Terminal Module) allows easy multiplexing of

redundant signals and facilitates fast installation and commissioning.

Emerson M-Series Plug and Play Components

Plug and Play Components. The system power supply assembly fits into any

power slot of any DeltaV power supply/controller carrier.

This not only simplifies system design, but also reduces spare parts inventory through interchangeability.

DIN-Rail Mounting. Power supply installation is simple.

Mount the power supply/controller carrier on the T-shaped DIN rail.

Then plug the system power supply into the carrier.

Internal Power Bus. The power supply/controller carrier contains an internal power bus.

You do not need to use external cables to connect the system power supply

to the DeltaV controller and I/O interface carriers.

Modular power supplies. You know the power requirements for today,

but what about the future? Build a solid foundation now and build on it later.

Modular power architecture allows you to install additional power supplies for controllers and I/O

subsystems.

Precision outputs. System power supplies accept a wide range of power

inputs and convert the inputs into precise power outputs.

Power Redundancy: DeltaV system power supplies can be redundant on a 1-to-N basis, while other

systems are 1-to-1.

This provides an economical solution for creating system redundancy.

Fault Detection. Undervoltage and overvoltage conditions are detected and logged to protect

the controller and I/O subsystems and to automatically cold-start the controller in the event of a high-

capacity power failure.

Standards compliance. The power supply is EMC and CSA compliant.

It is designed to comply with European ‘Power Factor Correction’ standards.

Immediate notification of power failure. The internal relay outputs change state and alert

the user if the input voltage fails or the system power fails.

In addition, an LED on the power supply housing displays the status of the power supply.

System and Field Power Isolation. The system power supply provides isolation

between the system power supply and the field power supply when the system

power supply and the field power supply are powered by the same 24-volt DC bulk power system.

Power Supply Removal. The system power supply is easy to remove/replace.

The bulk power cord connects to an easy-to-install connector instead of screw terminals.

Emerson M-Series DC to DC System Power Supplies

Product Description

The DC/DC System Power Supply is used to power DeltaV controllers and I/O interfaces

from a 12 or 24V DC bulk power supply that can be mounted next to the controller

in the power supply/controller carrier and provides the 5 and 3.3V DC power required by the controller.

It provides 5V and 3.3V DC power for the controller.

It also provides 12 VDC power for the I/O interfaces and up to 8 amps when powered from a 24 VDC bulk

power supply.

power slot of any DeltaV power supply/controller carrier.

ABB M4M Profibus network characteristics

Profibus network characteristics

The Profibus network extension by means of signal segmentation and regeneration

is limited to a maximum of 32 nodes/partners (master/slave) per segment;

On the other hand, the entire network can have up to 126 nodes/partners.

If you need to increase the length of the bus or use more than 32 stations, you must use repeaters.

Any repeater is a ‘load’ on the bus. Each new segment introduced 

must be terminated at both ends of the segment, the maximum length

of which depends on the baud rate; however, standard procedure is to connect up to 30 loads per

segment.

The transmission method for Profibus DP is the RS485 interface

(according to the EIA standard) using shielded twisted-pair cables.

The simple RS485 twisted-pair transmission method is ideally

suited for linear/tree networks with high transmission speeds.

The Profibus must always be terminated with two terminals.

As shown in the figure below, either terminal must consist of three resistors;

The terminals must be fed with a voltage of 0 to 5 volts DC,

otherwise their resistance is not equal to the characteristic impedance of the cable.

With this structure, the voltage on the bus is fixed when there are no active devices.

ABB M4M Network Analyser Transmission method

According to the IEC 61158/EN 50170 standard, Profibus DP (decentralised periphery)

is typically used to connect decentralised peripheral devices with fast response times.

The standard specifies node distances of up to 300 metres with bit rates

ranging from 9.6 kbps to 12 Mbps, using standard cables and maintaining maximum operating speed.

MOOG The G123-814 emits emissions well below the levels required for CE marking testing

Electromagnetic compatibility

The G123-814 emits emissions well below the levels required for CE marking testing.

However, the cable connecting the valve coil should be shielded to ensure that no interfering radiation is

emitted.

Connect both ends of the shielded cable to chassis earth. Use terminals 10 and 14 on G123-814.

Immunity to external interference radiation depends on careful wiring techniques.

The recognised method is to use shielded cables for all connections, the

The accepted method is to use shielded cable for all connections and to radially terminate

the cable shield with a suitable grounded cable gland where it enters the industrial steel enclosure.

If this is not possible, chassis ground screw terminals are available on the G123-814.

The length of bare wire should be minimised. Connect the shield at each end of the cable to chassis

ground.

Allow sufficient length of cable

so that the wires remain connected when the circuit card is removed from the housing. 

This allows the circuitry to be checked while the circuit card is still connected and operational.

For cables connected to the outside of the housing as well as for

cables connected to the adjacent DIN rail unit, an additional 100 mm is sufficient.

The cable to the valve coil carries 1 Amp and should be sized accordingly.

Cables with a conductor size of 0.2 mm2 are normally rated at 1 Amp and are suitable for cable lengths

up to 5 metres.
