PRODUCT: ROCKWELL AUTOMATION ICS Triplex T8461 Trusted TMR 24V DC/48V DC Output Module - 40 Channel
Product Overview:
The Trusted® Triple Modular Redundant (TMR) 24 Vdc / 48 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 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 TMR output channels per Module.
• Comprehensive, automatic diagnostics and self-test.
• Automatic line monitoring per channel 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
channel 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).
