10/100M 2FX4FE Industrial Switch



The IES1204-SFP series is a performance and cost-effective Industrial Ethernet Switch that meet the high reliability requirements of industrial network operations. It is designed to extend the distance of a network by converting Fast Ethernet data between twisted pair cabling and multi-mode or single-mode fiber-optic cabling.

The IES1204-SFP features 2 x 1000Base-X SFP Slot and 4 x 10/100Base-TX twisted-pair port. The IES1204-SFP provides two SFP slot for any MSA-complaint pluggable 155M SFP transceivers. The twisted-pair port has 4 x RJ-45 connector with a maximum operating distance of 100m.

The IES1204-SFP Industrial Fast Ethernet Switch is designed to stand up to extreme temperature, surges, vibrations, and shocks found in industrial automation, government, military, oil & gas, mining and outdoor applications, such as traffic management, oil and gas pipelines.

The IES1204-SFP series enables real-time deterministic network operation, requires no configuration and will instantly operate as soon as you power it up. Additionally, they can be installed by DIN-rail or wall-mounted, allowing users to deploy any mix of network conversions required.
