Description

The TIDA-010076 shows the transfer of 220-W power and 100-Mbit/s data over SPE. Communication systems in daisy-chain topology need significantly less hardware and wiring than conventional systems in star-topology. When combined with single-pair Ethernet (SPE, 100BASE-T1) and power over data line, the design gets simplified with fewer wires. Power and data travel over only two wires from node to node.

Features
  • SPE with 100 Mbit/s
  • One twisted pair for power and communication
  • Daisy-chaining of nodes
  • Protected against mis-wiring and surge
  • Engineered or dynamic link power
  • Tested for operating with the  66AK2Gx industrial communications engine
