操作模式（活動(dòng)、待機(jī)、教育）。

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).
