TMR 35 – 120 Vdc Digital Input
Module – 40 Channel
Introduction
The Trusted
TM
TMR 120V dc 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 1ms. 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.
2500V dc optical isolation barrier.
On-board Sequence of Events (SOE) reporting with 1ms 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)
