The SPIDER II 16TX EEC and SPIDER II 16TX/2DS-S EEC entry-level Ethernet switches are DIN-Rail mountable and use plug-and-play technology for quick and reliable installation.
The switches can be cascaded as often as required, permitting implementation of decentralized networks with short transmissionpaths, while considerably reducing the cost of cabling. Dual-speed optical uplinks and SFP transceivers for various types of fiber optic cables enable the bridging of distances up to 120 kilometers.
Using Gigabit SFP transceivers ensures that applications with high data volumes do not suffer from bottlenecks, so smooth communication is always guaranteed.


The SPIDER II 16TX EEC and SPIDER II 16TX/2DS-S EEC can be used anywhere where the network of devices is required via line or star topology. This makes these unmanaged switches suitable for a wide range of applications, including mechanical engineering and plant construction, where an everincreasing number of IP devices require field-level networking. Finally yet most importantly, these unmanaged switches are ATEX and ISA 12.12.01 approved - providing secure data communications, even in potentially explosive atmospheres.


  • High port density offering excellent value for money
  • Greatest possible flexibility thanks to dual-speed optical uplinks for SFP transceivers, including BIDI versions
  • Wide range of applications facilitated by the robust design and approvals for potentially explosive atmospheres (ATEX, ISA 12.12.01)
  • Extra wide operating temperature range from -40C to +70C
  • High level of electromagnetic compatibility, plus resistance to impacts and vibration
  • Redundant 24 V power supply
  • Compact dimensions (138 x 65 x 111 mm)
  • Rail-mounted
  • Activated by plug and play
  • Cascadable for cost-effective cabling
  • Perfectly geared to Ethernet cable from Belden and the complete product portfolio of Hirschmann Ethernet Switches
