Core Functions

Supervised safety DO for critical ESD solenoid/shutdown valve, real-time field circuit health inspection via pulse test function

TMR fault-tolerant output avoids spurious trip or fail-to-shutdown under single hardware failure

Online hot swap replacement during SIS running, channel-level fault location for quick field troubleshooting

TriStation software configure output logic, monitor real-time channel status and historical fault log

Application Scenarios

Oil&Gas Onshore/Offshore:Wellhead ESD shutdown solenoid, flare ignition valve safety drive

Refinery & Petrochemical:Reactor emergency cut-off valve, HIPPS safety relay output control

Thermal Power Plant:Boiler fuel trip valve, turbine emergency protection digital output

Chemical Plant:Reaction vessel overpressure shutdown actuator control

Brief Difference
