abb Triguard SC300E 3BNP004720R101 TMR Safety Products

and validating that all configuration

data is correct, eg. correct I/O

module, on-line/off-line hot repair

functions.

All I/O modules can be programmed

for a hot repair facility. A wrong or

faulty module in an allocated hot

repair I/O slot will not be accepted.

Hot repair slots are selected to be

next to the system I/O resident

module.

There are three ways to replace an

on-line I/O module:

• Module with no additional hot

repair slot – single slot hot repair

• Module has an unpopulated hot

repair partner slot – manual hot

repair

• Module with a populated hot repair

partner slot – hot repair

Field Termination Cards

The types of termination cards

available:

• 16 channel – digital input

• 32 channel – digital input

• 16 channel – digital output

• 16 channel – analogue input

• 4 channel – analogue output

• 16 channel – digital output with line

monitoring

• 4 channel – pulse input

DIN rail mounted termination cards

for field wiring can be supplied as an

easy to fit method to route field cables

to the Triguard SC300E system I/O

modules, and distribute field wetting

current to each I/O point.

A termination card has an associated

system cable fitted with DIN

connectors to provide the plug and

socket arrangement. Cable lengths can

be specified to suit the application.

Alternative cables with Elco

connectors or free wires at the field

end are available for third party

marshalling systems.

Power and fusing for the field circuits

are standard. Options are available to

suit all field configurations.

System cables from the Triguard

SC300E are also available with free

wire ends so that the system may

connect to a separate cable

marshalling and power/fusing system.

Cabinet Layouts

Optional cabinets to house the

Triguard SC300E TMR control system

are industry standard 19” rack

mounted configurations with a width

of 600mm and a depth of 800mm. The

layouts shown are based on a standard

2000mm high cabinets, and provide

front and rear access. Front access

only configurations are available.

System Structure

A major benefit of the Triguard

SC300E system is that it can be as

small as one chassis or as large as 15,

giving a 9,500 total I/O capacity. The

TMR bus extender modules and cable

sets are used to size the system to suit

the application. Interfacing to remote

TMR I/O chassis or gateway modules

to connect to DCS networks, can

be provided to suit a combined

distributed safety and control strategy.

A customer who has a future

requirement to add to an existing

system will find the Triguard SC300E

easy and economical to extend.

Forward and backward compatibility

means that users can readily intermix

CS300 and Triguard SC300E systems

using the same programming tools.

Application logic written for a CS300

system will run with minimum

modification on the Triguard SC300E.

A fully distributed safety system,

using the Triguard SC300E, can be

configured by utilising a Safeway

8000 bus structure and the

Triguard peer to peer safety

approved protocol.
