Trusted@ TMR)24VDC/48VDC digital output module interfaces with 40 field devices. T8403C triple diagnostic test is performed in the whole module, including current measurement and voltage on each part of the voting output channel. Tests were also carried out for stuck and stuck faults. The intra-module architecture of each of the 40 fault-tolerant output channels is realized through TMR. Provide automatic line monitoring of field equipment. T8403C function enabling module is used to detect open circuit and short circuit faults in field wiring and load equipment. For a paired slot configuration, two adjacent slots in a trusted chassis are configured for the same module function. One slot is the main slot and the other is the only auxiliary (or spare) slot. Two slots are at the back of the trusted chassis, and T8403C has a double-width I/O interface cable to connect the two slots to the public field terminal. During normal operation, the main slot contains active modules, such as the activation indicator on the front panel of the module.

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
