Rockwell T8461 ICS Triplex PLC

100% Original New Rockwell ICS Triplex T8461 PLC For Automation In Stock
ICS Triplex T846

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.

Upgrade Options for Non-ICS Triplex Products

As a result of numerous requests from our customers, we have developed an upgrade path for GE Fanuc 90/70 and 90/30 systems using the Trusted® processor while retaining Genius Bus I/O modules and cabling.
This option is in response to a request for a solution to the declaration of obsolescence from GE for the GE 90/70 and 90/30 processors and I/O systems and enables us to replace a GE Fanuc processor with a Trusted or AADvance® Control
System (depending on I/O requirements), through an interface to the original Genius Bus I/O, while still using the original cabling.
This is currently seen as a viable solution to upgrade old GE Fanuc systems to current technology Trusted systems without the need for lengthy or costly system shutdowns.

T8461 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).
