ICS Rockwell T8451 Trusted TMR 24Vdc Digital Output Module

ICSTT-RM280N-EN-P (PD-T8451)

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.

• Front Panel output status Light Emitting Diodes (LEDs) for each point indicate output 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.

• Outputs are powered in isolated groups of eight. Each such group is a Power Group (PG).
