SEL-2742
Managed RSTP or Managed OT SDN Switch
- This compact 12-port switch is designed for industrial sites and edge applications where space efficiency is critical. It natively supports DIN rail mounting, making it the ideal solution for narrow control cabinets or distributed facilities where traditional 19-inch rack mounting is not feasible. Additionally, it features PoE+ (Power over Ethernet Plus) to provide direct power to end devices such as IP cameras and VoIP phones.
Key Features
-
PoE+ Support
Provides IEEE 802.3at compliant PoE+ output on ports 5 and 6, delivering up to 30W per port.
Reduces installation costs and complexity by eliminating the need for separate power cabling for security cameras or wireless access points (APs). -
Industrial-Grade Durability
Operates reliably in extreme temperatures ranging from -40°C to +85°C.
Engineered with substation-level EMI immunity and high resistance to vibration and shock. -
OT SDN Security & Performance
When operated in SDN mode, it delivers the same robust features as the SEL-2740S: whitelist-based traffic control, high-speed failover in under 1ms, and centralized management. -
Dual Power Input
Supports redundant power configurations with 24 Vdc or 48 Vdc dual power inputs to ensure continuous operation.
Convenience features
-
DIN Rail & Surface Mounting
Its compact form factor allows for easy installation in tight spaces within control panels via DIN rail.
Optional surface-mount brackets are available for secure attachment to walls or flat panels. -
Centralized Management
Fully integrates with the SEL-5056 NMS, allowing operators to remotely monitor status and change configurations for switches installed in hard-to-reach locations, significantly enhancing maintenance efficiency. -
Alarm Contacts
Equipped with Form C alarm contacts that trigger immediately upon detecting system anomalies (e.g., over-temperature, link failure, or power loss).
Easily integrates with SCADA systems or external local alarm devices. -
Status LEDs
Front-panel LEDs provide real-time visual diagnostics for link status, connection speed, and PoE power delivery, allowing for rapid on-site troubleshooting.
