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).

• TϋV Certified IEC 61508 SIL 3.

The Trusted® TMR 24 Vdc Digital Input Module is a member of the Trusted

range of Input/Output (I/O) modules. All Trusted I/O Modules share common

functionality and form. At the most general level, all I/O Modules interface to

the Inter-Module Bus (IMB) which provides power and allows communication

with the Trusted TMR Processor. In addition, all Modules have a field interface

that is used to connect to module specific signals in the field. All Modules are

Triple Modular Redundant (TMR).
