Description
TRICONEX T8480 – TMR Analog Output Safety Module for SIS Systems
Product Overview
The T8480 is a high-reliability TMR (Triple Modular Redundancy) analog output safety module manufactured by TRICONEX (ICS TRIPLEX), engineered for critical Safety Instrumented Systems (SIS) in process industries. This industrial-grade module provides stable 4–20 mA analog control outputs to regulate field actuators, control valves and process modulation equipment. Adopting triple redundant voting architecture, it eliminates single-point failures and ensures bumpless, consistent analog output even under partial hardware faults. The TRICONEX T8480 integrates comprehensive self-diagnosis and line monitoring functions, delivering high-precision, fault-tolerant process control for high-risk continuous production environments.
