PRODUCT INFORMATION
Product Overview
The General Electric IS420ESWBH2A is an unmanaged Ethernet/IONet switch designed for Mark VIe industrial control systems. This switch provides network communication handling across plant automation architectures. It features two 100Base-FX multi-mode fiber ports utilizing LC-type connections. The assembly also incorporates high-durability RJ45 copper interfaces.
The internal switch architecture buffers continuous streams of incoming multicast and broadcast packets. Internal memory allocates buffering capacity for one packet per port. An integrated soft-start circuit controls power sequencing. This circuit limits inrush current to less than two hundred percent of standard operating current.
