Trusted TMR 35 to 120 Vdc Digital Input Module –

40 Channel

Product Overview

The Trusted®TMR 120 Vdc Digital Input Module interfaces to 40 field input devices. Fault tolerance

is achieved through a Triple Modular Redundant (TMR) architecture within the Module for each of

the 40 input channels.

Each field input is triplicated and the input voltage is measured using a sigma-delta input circuit.

The resulting field voltage measurement is compared to user configurable threshold voltages to

determine the reported field input state. When a line-monitoring device is installed at the field

switch, the Module can detect open and short circuit field cables. Line monitoring functions are

independently configured for each input channel. The triplicated voltage measurement, coupled

with on-board diagnostic testing, provides comprehensive fault detection and tolerance.

The Module provides on-board Sequence of Events (SOE) reporting with a resolution of 1 ms. A

change of state triggers an SOE entry. States are determined by voltage thresholds that can be

configured on a per channel basis.

Features:

•40 Triple Modular Redundant (TMR) input channels per Module.

•Comprehensive, automatic diagnostics and self-test.

•Selectable line monitoring per channel to detect open circuit and short circuit field wiring

faults.

•2500 V impulse withstand opto/galvanic isolation barrier.

•On-board Sequence of Events (SOE) reporting with 1 ms resolution.

•Module can be hot-replaced on-line using dedicated Companion (adjacent) Slot or SmartSlot

(one spare slot for many modules) configurations.

•Front Panel input status LEDs for each channel indicate input status and field wiring faults.

•Front panel module status LEDs indicate module health and operational mode (Active,

Standby, Educated).

•TϋV Certified IEC 61508 SIL 3.

SCOPE

This manual specifies the maintenance requirements and describes the procedures to assist

troubleshooting and maintenance of a Trusted system.

WHO SHOULD USE THIS MANUAL

This manual is for plant maintenance personnel who are experienced in the operation and

maintenance of electronic equipment and are trained to work with safety systems.

SYMBOLS

In this manual we will use these notices to tell you about safety considerations.

SHOCK HAZARD: Identifies an electrical shock hazard. If a warning label is fitted, it

can be on or inside the equipment.

WARNING: Identifies information about practices or circumstances that can cause

an explosion in a hazardous environment, which can cause injury or death,

property damage or economic loss.

ATTENTION: Identifies information about practices or circumstances that can cause

injury or death.

CAUTION: Identifies information about practices or circumstances that can cause

property damage or economic loss.

BURN HAZARD: Identifies where a surface can reach dangerous temperatures. If a

warning label is fitted, it can be on or inside the equipment.

This symbol identifies items which must be thought about and put in place when

designing and assembling a Trusted controller for use in a Safety Instrumented

Function (SIF). It appears extensively in the Trusted Safety Manual.

IMPORTANT Identifies information that is critical for successful application and understanding of

the product.

NOTE Provides key information about the product or service.

TIP Tips give helpful information about using or setting up the equipment.

WARNINGS AND CAUTIONS

WARNING: EXPLOSION RISK

Do not connect or disconnect equipment while the circuit is live or unless the area is

known to be free of ignitable concentrations or equivalent

AVERTISSEMENT - RISQUE D’EXPLOSION

Ne pas connecter ou déconnecter l’équipement alors qu’il est sous tension, sauf si

l’environnement est exempt de concentrations inflammables ou équivalente

MAINTENANCE

Maintenance must be carried out only by qualified personnel. Failure to follow these

instructions may result in personal injury.

CAUTION: RADIO FREQUENCY INTERFERENCE

Most electronic equipment is influenced by Radio Frequency Interference. Caution
