ICS Triplex T8461
The Trusted® Triple Modular Redundant (TMR) 24V DC / 48V DC 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 of 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.
ICS Triplex T8461 provides onboard Sequence of Events (SOE) reporting a resolution of 1 ms. An output change of state triggers an SOE entry. Output states are automatically determined by voltage and current measurements onboard 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.
• 2500V impulse withstand opto/galvanic isolation barrier.
• Automatic overcurrent protection (per channel), no external fuses required.
• 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 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).
