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.

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
