Description
The ICS Triplex T8461C is a Trusted TMR 24V DC/48V DC Output Module, designed for high-integrity safety and control systems where fault tolerance and reliability are critical. It is part of the Trusted product line, widely used in industries.
Applications
Nuclear Power: Controls reactor isolation valves with dual-voltage safety circuits.
Deepwater Oil & Gas: Drives high-load ESD hydraulic valves over long distances.
Fine Chemicals: Monitors reactors using precise current and voltage measurement.
Metal Smelters: Records faults with high-precision event sequencing.
Gas Compression: Protects compressors with isolation and short-circuit protection.
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.
Fault Detection/Testing
Extensive diagnostics automatically detect module faults and verify critical circuits.
TMR architecture provides fault tolerance, allowing operation to continue after a single fault without process interruption.
Faults are indicated via front panel status LEDs and reported to the TMR processor.
Under normal operation, all three LEDs are green. When a fault occurs, one LED flashes red, and the module should be investigated and replaced if necessary.
