Ethernet I/O Module/Modbus TCP/8DI/8DO

  • Built-In Webserver: configuration, monitoring with standard Webbrowser
  • Modbus UDP/TCP
  • I/O Pair Connection
  • 8 isolated digital input channels (wet contact) with 32-bit counter
  • 8 isolated digital output channels (open-collector, max 300 mA per channel)
  • Power Supply: 10-30 VDC (ET-7044) or 12-48VDC / POE (PET-7044)
  • DIN-Rail Mounting




The ET-7044/PET-7044/ET-7244/PET-7244 provides 8 wet contact digital input channels and 8 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 300 mA load. The power-on value and safe value of digital output channel are programmable. It can safely be used in applications where hazardous voltages are present.
