Product overview
The Trusted® dual 24 Vdc digital input module interfaces to 60 field input devices. Fault tolerant
This is achieved through the "one out, two D" (102d) voting architecture within the module
60 input channels.
Each field input is repeated and the input voltage is measured using the σ-δ input circuit.
The generated field voltage measurement is compared to a user-configurable threshold voltage
Determine the field input status for the report. When line monitoring devices are installed onsite
When switching, the module can detect field cable breaks and short circuits. Line monitoring functions are available
Individually configured for each input channel. Dual voltage measurements, coupled with board diagnostic tests, provide comprehensive fault detection and fault tolerance.
The module provides onboard event sequence (SOE) reports with a resolution of 1 millisecond. single
A change in state triggers the SOE entry. The state is determined by the voltage threshold
Configuration on a per-channel basis.
Features:
• 60 repeat input channels per module.
• Comprehensive, automated diagnostics and self-tests.
• Line monitoring is optional for each channel to detect open and short field wiring
The disadvantages.
•2500v pulses withstand optical/electrical isolation barriers.
• Onboard Event sequence (SOE) reports with a resolution of 1ms.
• 50/60 Hz digital filtering can be configured to reduce field-induced noise.
• Modules can be hot replaced online using dedicated companion (adjacent) slots or SmartSlot
(One standby slot for multiple modules) Configuration. Front panel module status indicator
Module health and run modes (active, standby, Run).
