The Trusted® TMR 24 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 onboard diagnostic testing,
provides comprehensive fault detection and tolerance.
The module provides onboard 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.
• Onboard Sequence of Events (SOE) reporting with 1 ms resolution.
• Module can be hot-replaced online 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.
