Ethernet I/O Module/Modbus TCP/12DI/6DO

  • Built-In Webserver: configuration, monitoring with standard Webbrowser
  • Modbus UDP/TCP
  • I/O Pair Connection
  • 12 isolated digital input channels (wet contact) with 32-bit counter
  • 6 isolated digital output channels (open-collector, max 100 mA)
  • Power Supply: 10-30 VDC (ET-7050) or 12-48VDC / POE (PET-7050)
  • DIN-Rail Mounting




The ET-7050/PET-7050 provides 12 wet contact digital input channels and 6 sink-type digital output channels. It features optical isolation for 3750 Vrms of transient overvoltage protection but doesn’t provide channel-to-channel isolation. Each input channel can be used as a 32-bit counter and each output channel can drive 100 mA load. The power-on value and safe value of digital output channel are programmable. In some industrial applications, the user can connect the output channel of ET-7050/PET-7050 to the RM series relay module to switch inductive loads.
