System compatibilityIS420ESWBH3A belongs to GE Mark VIe DCS control family. Works with Mark VIe controller, I/O modules and turbine safety control system. Widely applied on gas / steam turbine power generation control system.

Function

IS420ESWBH3A is IONet industrial ethernet switch manufactured by GE Vernova. It provides deterministic real-time network communication backbone for Mark VIe distributed control system. It exchanges critical control commands, process data and system diagnostic information between turbine controller and field I/O modules. Redundant power and RSTP protocol improve network reliability to avoid single point failure in power plant control network. LED indicators show port link status and module health condition.

Installation

Follow lockout/tagout safety procedure before installation. Cut off all control cabinet power. Fix IS420ESWBH3A on DIN rail or panel bracket. Connect redundant 24VDC power supply and RJ45 network cables. Configure network parameters according to Mark VIe system manual. Power on and verify link status and data communication.

Interface

Redundant 24VDC power terminal,16pcs RJ45 10/100 copper ports,fiber uplink port,link and fault status LED for GE IS420ESWBH3A.
