Trusted TMR 120 Vac Digital Input Module 40
Channel
Product Overview
The Trusted® TMR 120 Vac Digital Input 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 field voltage signal is digitally processed to compute the alternating current (ac) amplitude,
which is compared to fixed threshold voltages to determine the reported field input state. The
triplicated voltage measurements, coupled with on-board diagnostic testing, provide
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 for each channel are determined by comparing the
input signal amplitude with fixed voltage thresholds on a per channel basis.
Features:
•40 Triple Modular Redundant (TMR) input channels per Module.
•Comprehensive, automatic diagnostics and self-test.
•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 Light Emitting Diodes (LEDs) for each channel indicate input status
and open inputs.
•Front Panel Module status LEDs indicate Module health and operational mode (Active,
Standby, Educated).

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
should be exercised with regard to the use of portable communications equipment
around such equipment. Signs should be posted in the vicinity of the equipment
cautioning against the use of portable communications equipment.
CAUTION:
The Module PCBs contains static sensitive components. Static handling precautions
must be observed. DO NOT touch exposed connector pins or attempt to dismantle a
Module.
