Power consumption 5~12W
Protocol IEEE802.3/802.3u, store and forward architecture, supports IEEE1588 precision clock synchronization (1 μ s level)

3、 Same model differentiation (ESWA/ESWB suffix H3A differentiation)
IS420ESWAH3A: 8-port electrical port (this model), small size, short distance networking within a single cabinet
IS420ESWBH3A: 16 all electrical ports, used in a multi I/O centralized cabinet, with doubled ports
H1A/H2A models with fiber optic ports are used for long-distance fiber optic interconnection between cabinets, while H3A models with pure copper ports have no optical ports

4、 Application scenarios
Thermal power/gas turbine: 9E/9F gas turbine, steam turbine Mark VIe main control cabinet, connected to controller, I/O card, EX2100 excitation system, IONet control intranet network
Petrochemical/Oil and Gas: Gas Compressor Unit, Refining Equipment SIS Safety Instrumented System, Explosion proof and Severe Operating Condition Control Cabinet Communication
Metallurgical, water treatment, and combined cycle power plants: key unit DCS/SIS system cabinet switching network

5、 Selection&Spare Parts Description
Alternative solution: If the original factory does not have a new model for direct replacement, priority should be given to purchasing brand new inventory with original packaging in case of malfunctions; Non standard replacement requires compatibility with GE IONet private communication protocol
Warranty: Regular 1-year warranty for spare parts on the market (brand new and original)
Installation: DIN rail buckle installation, compatible with standard industrial control cabinet card slots
