The Trusted? TMR 24 Vdc Digital Input module interfaces to 40 field b devices. Fault tolerance is achieved through a Triple Modular Redundant
(TMR) architecture within the module for each of the 40 b channels.Each field b is triplicated and the b voltage is measured using a sigma-delta b circuit. The resulting field voltage measurement is compared to user configurable threshold voltages to determine the reported field b 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 b 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) b 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 b status LEDs for each channel indicate b status and field wiring faults.
? Front panel module status LEDs indicate module health and operational mode (Active, Standby, Educated).
? T?V Certified IEC 61508 SIL 3.
