INTRODUCTION

PURPOSE

The

TDO16AIN

16

-

channel

digital

output

termination

card

acts

as

an

interface

between

the

digital

output

circuits

of

an

SC300E

chassis

and

the

field

devices

which

they

control.

It provides:

• Screw

terminals

for

the

field

wiring

• Power

supply

inputs

for

the

field

devices

• Fuse

protection

for

the

field

loops

with

local

and

remote

indication

of

fuse

failure

•

Overvoltage protection

• Dummy

loads

for

unused

digital

output

channels

—

to

prevent

spurious

operation

of

latent

fault

detection

circuits

in

the

associated

digital

output

module.

(Dummy

loads

are

only

to

be

connected

to

outputs

which

are

not

used).

This

document

is

intended

to

provide

a general

understanding

of

the

function

of

the

TDO16AIN,

sufficient

to

enable

basic

maintenance

operations

to

be

effected

in

the

field.

Power

Has

four

separate

connectors

(FS1,

FS2,

FS3

and

FS4)

for

dc

power

supplies.

The

four

positive

supplies

feed

individual

sections

of

the

digital

outputs

via

common

buses.

The

buses

are

linked

together.

For

lightly

loaded

applications

(e.g.

6A)

all

the

required

power

can

be

supplied

via

one

connector.

For

highly

loaded

applications

(e.g.

16A)

use

multiple

power

connectors.

THEORY OF OPERATION

Figure

-

a circuit

diagram

of

a typical

digital

output

channel.

Power

supplies

for

the

termination

cards

are

normally

provided

by

a Power

Distribution

Panel

PDD24.

Power

for

th

e digital

output

channels

is

distributed

as

shown

in

Figure

2

-

3 . Soldered

links

LK1

to

LK4

are

normally

present,

and

in

low

load

applications,

external

power

can

be

connected

to

any

one

of

the

four

inputs

FS1

to

FS4.

For

high

load

applications,

or

where

t

he

channel

groups

require

different

supply

voltages,

cut

the

links

and

supply

FS1

to

FS4

individually.

Each

digital

output

channel

is

powered

from

a common

+ve

bus.

An

indicating

fuse

is

fitted

in

the

digital

output

signal

line

to

the

field

device.

The

‘fuse

failed’

output

from

each

fuse

is

connected

to

a common

alarm

bus.

If

any

fuse

fails,

local

indication

is

provided

by

the

illumination

of

the

Fuse

blown

LED

LD1.

A signal

to

operate

a remote

alarm

is

available

at

Alarm

output

PL1.

The

-

ve

bus

may

be

gr

ounded

via

TS1

if

required,

preventing

the

power

supplies

from

‘floating’

when

the

chassis

cable

is

disconnected.

all

-

passive

circuitry

that

is

extremely

robust.

Servicing

operations

will

therefore

not

extend

beyond

the

replacement

of

blown

fuses.

CAUTION

Before

replacing

a blown

fuse,

ascertain

the

cause

of

failure,

and

take

the

appropriate

remedial

action.

CONFIGURATION

Links

LK1

to

LK4

are

connected
