Trusted TMR Analog Output 40-Channel Module ICS Triplex T8480C

Product Overview

The ICS Triplex T8480C provides high-integrity analog control signals for critical field actuators within the Trusted™ Triple Modular Redundancy (TMR) architecture. It manages up to 40 isolated analog output channels, typically driving 4-20mA control loops for valves, positioners, and variable speed drives. The "C" designation signifies that the module features conformal coating, offering superior protection against corrosive gases and humidity. We supply this unit as 100% brand new and original, ensuring your Safety Instrumented System (SIS) meets SIL3 requirements with hardware in pristine condition.

Technical Specifications

Engineering Advantages

• Execute High-Integrity Control: The T8480C utilizes a triplicated output structure. Internal 2-out-of-3 (2oo3) hardware voting ensures that the module produces the correct output signal even if a single internal processing path fails. This prevents unauthorized actuator movement during hardware discrepancies.

• Master Harsh Environments: The specialized conformal coating shields the PCB from atmospheric contaminants, moisture, and chemical vapor. This makes the T8480C the definitive choice for offshore oil rigs, chemical refineries, and wastewater treatment facilities.

• Detect Loop Anomalies Instantly: Integrated diagnostic circuitry monitors the integrity of the field wiring and the connected load. The module identifies open circuits or high-impedance faults in real-time, allowing maintenance teams to address field-side issues before they compromise the safety function.

• Streamline Cabinet Density: Packing 40 high-integrity analog outputs into a single module optimizes rack space. This high density reduces the physical footprint of the control system, which is vital for space-constrained control rooms and offshore modules.

FAQs

• Does the T8480C support hot-swapping during live operation?

  Yes. The Trusted™ architecture allows you to replace the T8480C module while the system is powered and active. The redundant backplane ensures that the safety logic remains uninterrupted during the module exchange.

• Can this module drive high-impedance solenoid valves?

  The T8480C is optimized for standard 4-20mA control loops. For high-current discrete solenoid loads, we recommend using the Trusted Digital Output series. Always verify the load impedance against the module’s maximum driving capacity in the technical manual.

• What is the benefit of the conformal coating on the "C" version?

  The coating provides an insulation layer that prevents "dendrite growth" and corrosion caused by humidity and H2S gases. This significantly extends the lifecycle of the module in aggressive industrial environments compared to the non-coated version.

• How do you guarantee the "100% Brand New" status?

  Every T8480C we ship is factory-original, unused, and sealed. We provide full serial number traceability and verify the hardware revision to ensure you receive the most reliable, latest-standard safety hardware available.
