T9801 Trusted®TMR 24 Vdc digital input module

T9801  Trusted®TMR 24 Vdc digital input module

Features:

• 40 three-mode redundant (TMR) input channels per module.
• Comprehensive, automated diagnostics and self-tests.
• Line monitoring is optional for each channel to detect open and short field connection faults.
• 2500V pulse resistant photoelectric isolation barrier.
• On-board Event Sequence (SOE) reporting at 1ms resolution.
• Can be configured with 50/60 Hz digital filtering to eliminate field noise.
• Online hot replacement modules can be used with dedicated matching (adjacent) slots or smart slots

For each of the 40 input channels, this is achieved through a three-mode redundancy (TMR) architecture within the module.
Each field input is tripled, and a Sigma Delta input circuit is used to measure the input voltage.
The resulting field voltage measurement is compared with a user-configurable threshold voltage to determine the reported field input status. When installing line monitoring devices on site
Switch, this module can detect open and short circuits in field cables. The line monitoring function is configured independently for each input channel. Triple voltage measurement, coupling
Comprehensive fault detection and fault tolerance through on-board diagnostic testing.
The module provides on-board Event sequence (SOE) reporting with a resolution of 1ms.
A change in state triggers an SOE entry. The state is determined by a voltage threshold that can be configured on a per-channel basis.
