ICSTT-RM280N-EN-P (PD-T8451)
Trusted TMR 24 Vdc Digital Output Module – 40
Channel
Product Overview
The Trusted® TMR 24 Vdc Digital Output Module interfaces to 40 field devices. Triplicated
diagnostic tests are performed throughout the Module including measurements for current, and
voltage on each portion of the voted output channel. Tests are also performed for stuck on and
stuck off failures. Fault tolerance is achieved through a Triple Modular Redundant (TMR)
architecture within the Module for each of the 40 output channels.
Automatic line monitoring of the field device is provided. This feature enables the Module to detect
both open and short circuit failures in field wiring and load devices.
The Module provides on-board Sequence of Events (SOE) reporting with a resolution of 1 ms. An
output change of state triggers an SOE entry. Output states are automatically determined by
voltage and current measurements on-board the Module.
This Module is not approved for direct connection to hazardous areas and should be used in
conjunction with Intrinsic Safety Barrier devices.
Features
• 40 Triple Modular Redundant (TMR) output points per Module.
• Comprehensive, automatic diagnostics and self-test.
• Automatic line monitoring per point to detect open circuit and short circuit field wiring and
load faults.
• 2500 V impulse withstand opto/galvanic isolation barrier.
• Automatic over-current protection (per channel), no external fuses required.
• On-board Sequence of Events (SOE) reporting with 1 ms resolution.
• Module can be hot-replaced on-line using dedicated Companion (adjacent) Slot or SmartSlot
(one spare slot for many Modules) configurations.
