General Electric IS42yESWBH1A Industrial Ethernet Switches
Core Hardware and Port Configuration
Port Combination: 16 x 10/100Base-TX RJ45 copper ports + 1 x 100Base-FX multimode LC fiber optic port; supports HP-MDIX auto-sequencing, 10/100M auto-negotiation, full/half-duplex negotiation, IEEE 802.3x flow control; RJ45 copper ports withstand 200 mating cycles.
Switching Performance: 256KB buffer, 4K MAC address table, non-blocking full-switching architecture, ensuring low-latency transmission of real-time control data, compatible with Mark Vie IONet real-time communication protocol.
Power Supply and Installation: 24-28VDC redundant power input (diode OR protection), supports hot-swapping; DIN rail mounting, requires dedicated clips (259B2451BVP1 for parallel rails, BVP2 for vertical rails), natural convection cooling, no fan required.
Fiber optic characteristics: 100Base-FX multimode LC port, transmission distance ≤2km, suitable for short to medium distance inter-factory communication; requires GE dedicated IR SFP multimode optical module.

Redundancy and Safety Features
Power Redundancy: Dual 24-28VDC inputs, diode OR protection, hot-swappable replacement, avoiding single-point-of-failure power supply.
Harsh Environment Resistance: Metal casing, strong EMC performance, suitable for power plants, petrochemical plants, and other environments with strong electromagnetic interference and vibration shock.
Explosion-proof Compliance: Class 1 Div 2/ATEX certified, can be deployed in control cabinets in hazardous areas, meeting SIS system safety requirements.
Typical Applications and Deployment Recommendations
High-Density Local I/O Access: 16 copper cable ports connect to a large number of local I/O modules and controllers; multimode fiber ports connect to the IONet backbone, suitable for centralized I/O communication scenarios in large turbine units.
Short-to-Medium-Range Multimode Fiber Expansion: Multimode fiber ports connect to the IONet multimode backbone, connecting to remote operating stations or area controllers, suitable for short-to-medium-range (≤2km) inter-plant communication.
Security Control Network Expansion: The SIS security system's regional switch connects security I/O modules and security controllers, ensuring reliable transmission of security control signals.
Spare Parts Upgrade: Directly replaces aging 16-port switches, increasing port density and redundancy; no configuration changes are required during replacement—it's plug-and-play.
