Ethernet I/O Module with 16-ch DI
 
 
  ~ NEW ~
Model: ET-7051/PET-7051 Model: ET-7251/PET-7251
 
  • Built-in Web Server
  • Web HMI
  • Support for both Modbus TCP and Modbus UDP Protocols
  • Communication Security
  • 2-port Ethernet Switch for Daisy-Chain Topology
  • Dual Watchdog
  • Wide Operating Temperature Range: -25 ~ +75°C
  • I/O Pair Connection
  • Built-in I/O
    • DI/Counter: 16 Channels
 
The ET-7051/PET-7051/ET-7251/PET-7251 provides 16 wet contact digital input channels. Each input channel can be used as a 32-bit counter. It features optical isolation for 3750 Vrms of transient overvoltage protection but doesn’t provide channel-to-channel isolation. It can safely be used in applications where hazardous voltages are present.
