TRICONEX RO3451 Relay Output Module

TRICONEX RO3451 Relay Output Module

Description

RO3451 is a dedicated relay output module for Triconex Tricon fail-safe safety control system. It is used in conjunction with the matching output base plate. Through the relay contacts, it outputs switch control signals to drive on-site solenoid valves, audible and visual alarms, safety shut-off valves and other actuators. It is mainly used in SIS safety interlock action control in petrochemical, power plants and natural gas pipelines.

The module is equipped with a three-redundant TMR safety architecture. It has independent isolated relay channels, output signals with fault self-checking function, and can monitor contact abnormalities in real time. The standardized rack installation design is compatible with standard system cabinets. The relay contacts are isolated strongly, can resist on-site electromagnetic interference, and can stably output critical interlock instructions such as safety shutdown and alarms.
