Product performance
Deterministic real-time industrial exchange: Optimized for gas/turbine control IONet network, with low forwarding delay, ensuring mill speed, temperature, valve and other control signals are transmitted in millisecond synchronization.
Dual redundant DC power supply: Two independent 24VDC inputs, single power failure does not interrupt network communication, meeting the high reliability requirements of power plant uninterrupted control.
Fanless maintenance-free design: All-metal heat dissipation housing, capable of withstanding high temperatures, dust and vibration environments in power plants, with no risk of fan failure during long-term operation.
Strong industrial electromagnetic interference resistance: Meets the strict EMC standards of the power industry IEC61850-3, resisting harmonic interference from frequency converters and large-power excitation equipment.
Plug-and-play non-managed architecture: No configuration required, automatically forwards data upon power-on, simple on-site operation and maintenance, compatible with multi-card star network convergence.
Independent port fault isolation: Short circuit or open circuit of a single port only disconnects the corresponding node, without affecting the remaining 15 network communications of the entire machine.
Wide temperature all-weather compatibility: Can be directly started at low temperatures, does not reduce capacity under full load at high temperatures, compatible with harsh working conditions in power plant boiler rooms and turbine rooms.
