DESCRIPTION

The Trusted

TMR Analogue Output

module interfaces to 40 field output

devices. Outputs are arranged in five

groups of eight outputs. All outputs in

a group share a common power

source and return. Fault tolerance is

achieved through Triple Modular

Redundancy (TMR) within the same

module for each of the 40 output

channels.

The module provides on-board

Sequence of Events (SOE) reporting

with a resolution of 1ms. The “event”

is the actual sensing of the field

device loop current. Each triplicated

section (slice) of the module receives

output data from the Trusted

TMR

Processor and sends its data to an

internal safety layer hardware voter.

Each slice uses the voted data to

control the outputs. Every output

channel consists of a six-element

voted array. The output switch array

provides fault tolerant, uninterrupted

control under an output switch failure

condition. Output switching and fault

diagnostics comply with the

demanding requirements of IEC-

61508 SIL-3 for First Fault - Fault

Tolerant, and Second Fault - Fail

Safe outputs.

When a module fault is detected, the

Trusted

TMR Processor will flag the

unhealthy condition, indicating the

need to replace the module. Control

continues until a replacement

(healthy) module is available.

Replacement modules can be located

in a standby slot next to the module

or in a designated SmartSlot with a

temporary connection to the same

Trusted

Termination Assembly.

Each output is user configurable to

perform line monitoring of the

connected field devices to detect field

wiring and load failures. Automatic

over-current protection is inherent in

every output circuit which eliminates

the need for fuses.

Modules may be placed in any I/O

module slot in a Trusted

Processor

Chassis or Expander chassis. Once

the I/O module configuration is set,

mechanical keying is available on all

I/O modules to prevent inserting a

module into an incorrect slot.

Configuration of the module is carried

out using the Trusted

Toolset

running on an Engineering

Workstation. Once configured and

loaded into the Trusted

Controller,

replacement modules are on-line

educated by the TMR Processor.
