The F880 fieldbus power system is designed to provide redundant power for

eight Foundation™ fieldbus H1 segments when used with Yokogawa ALF111

fieldbus cards. The F880 module carrier has system connectors for direct

connection to two redundant pairs of fieldbus cards using Yokogawa AKB336

cables.

Power for the fieldbus segments is provided by two power modules – F801s

or F802s – operating in a redundant configuration (loadsharing).

Failure alarms, galvanic isolation, power conditioning and segment termination

are incorporated into each F80x module. In simplex applications, a single F80x

module may be used. Termination of the fieldbus segments is automatically

maintained when single or redundant F80x modules are fitted.

A separate physical layer diagnostics module may be installed on

the carrier to automatically collect and distribute additional diagnostic

information for each of the eight fieldbus segments. For more

information see the F809F product specification.

The F80x module provides galvanic isolation between the 24V DC

input power and the fieldbus segments, as required by the IEC61158

2 fieldbus standard and the Fieldbus Foundation™ FF-831 validation

test for power supplies. There is also galvanic isolation between the

fieldbus segments, thereby preventing multiple segment failures due

to ground faults on more than one segment. Each segment has its

own fieldbus power conditioner and current limitation.

Redundant 24V DC (nom.) input power is connected to the F890

carrier using two-part pluggable connectors. Field wiring connections

are available with either pluggable screw terminals (F890-PS), or

pluggable spring clamp terminals (F890-PC).

Each F80x module monitors the output of the eight fieldbus

segments and indicates an alarm by means of a built-in, normally closed

relay if any of the segments is shorted, or below the minimum output

voltage threshold. Failure of either of the bulk power input supplies

is also annunciated. The alarm contacts are volt-free and galvanically

isolated from other circuitry. Connections to the alarm relays are made

via terminals on the F890-CA carrier. A separate alarm module is not

required for this function. LED indicators also show the status of each

F80x module and the eight individual segments. In normal operation,

each segment LED is lit, showing that the segment is powered. If a

segment is shorted, this LED is extinguished, and the module Alarm

LED is lit.

The F890 fieldbus power system is designed to provide redundant

power for eight Foundation™ fieldbus H1 segments when used with

the Emerson DeltaV or another non-proprietary cabled fieldbus system.

Power for the fieldbus segments is provided by two power modules

– F801s or F802s – operating in redundant configuration (load sharing).

Failure alarms, galvanic isolation, power conditioning and segment

termination are incorporated into each F80x module. In simplex

applications, a single F80x module may be used. Termination of

the fieldbus segments is automatically maintained when single or

redundant F80x modules are fitted.

For extreme reliability, the module carrier has no components

and only provides interconnections between the power modules

and external connections. It is supported in a rigid metal frame that

protects the circuit board from mechanical damage. Secure DIN-rail

mounting is provided by integrated fixings.

DESCRIPTION

For maximum reliability, the module carrier contains no components and only provides

interconnections between the power modules and the external connections. The

carrier circuit board is supported in a rigid metal frame that protects it from mechanical

damage. Secure DIN-rail mounting is provided by integrated fixings. The F801 or

F802 module provides galvanic isolation between the 24V DC input power and the

fieldbus segments, as required by the IEC61158-2 fieldbus standard and the Fieldbus

FoundationTM FF-831 validation test for fieldbus power supplies. There is also galvanic

isolation between the fieldbus segments, thereby preventing cross-talk between

segments in the event of ground faults in the field wiring. Each segment has its own

current limitation and passive fieldbus power conditioner. Termination of the fieldbus

segment is automatically maintained when single or redundant F801 or F802 modules

are fitted. The F880-Cx carrier is equipped with connectors that will accept an F809F

diagnostic module. The module continuously monitors the performance of each of the

eight fieldbus segments, providing information on the network health.

Each Power Module has indicator LEDs to show both its status and that of the eight

segments under power. In normal operation, each green ‘Segment’ LED is lit, showing

that the segment is powered. If a segment is shorted, or its voltage is below the rated

output, its LED is extinguished, and the red ‘Alarm’ LED is lit. Redundant 24V DC (nom.)

input power is connected to the F880-Cx carrier using two-part pluggable connectors.

Field wiring connections are available with either pluggable screw terminals (F880-*S)

or pluggable spring clamp terminals (F880-*C).

The F880 redundant fieldbus power supply is designed to provide redundant power

for eight (8) Foundation fieldbusTM H1 segments. Connections are provided on the

F880-Cx Carrier for two redundant pairs of Yokogawa ALF111 fieldbus cards using

Yokogawa AKB336 cables. Power for the eight fieldbus segments is provided by two

F801 or F802 Power Modules mounted to the carrier and operating in a redundant

configuration. Failure alarms, galvanic isolation, power conditioning and segment

termination are incorporated into each Power Module. A single Power Module may

be used where redundancy is not required.

Three variants of carriers are available in the F880 family to be used in two different

types of installations. For large installations where multiple F880 systems will be

installed in a cabinet, there are Left (F880-CL) and Right hand (F880-CR) versions

that make cabinet wiring symmetrical – see Figure 2b. In smaller installations where

carriers are not installed side-by-side, the F880-CA carrier provides terminal numbering

and consistent connector polarity.

Directional Antennas

A directional antenna provides high gain in the forward direction, but lower gain in other directions. This type of

antenna may be used to compensate for coaxial cable loss for installations with marginal radio path. Directional

antennas can be any of the following:

• Yagi antenna with a main beam and orthogonal elements

• Directional radome, which is cylindrical in shape

• Parabolic antenna

Yagi antennas should be installed with the main beam horizontal, pointing in the forward direction. If the Yagi

antenna is transmitting to a vertically mounted omni-directional antenna, the Yagi elements should be vertical. If

the Yagi is transmitting to another Yagi, the elements at each end of the wireless link need to be in the same plane

(horizontal or vertical).

Directional radomes should be installed with the central beam horizontal, and must be pointed exactly in the

direction of transmission to benefit from the gain of the antenna.

Bench Test and Demo System Setup

Care must be taken with placement of antenna in relation to the radios and the other antennas. Strong radio signals

can saturate the receiver, hindering the overall radio communications. When setting up a bench test, demonstration,

or short range system, the following considerations should be taken into account for optimum radio performance

and reduced signal saturation.

• Reduce radio transmit power by adjusting the transmit power level on the Radio webpage (see “4.6 Radio

Configuration” on page 33).

• If using demo antennas on each end, fit a 20 dB 5W coaxial attenuator in-line with the coaxial cable.

• Antennas must be kept a suitable distance from each other. Check the receive signal strength on the

Connectivity page of the module and ensure that the level is not greater than –45 dB.
