ET-7253 CR ICP DAS Digital IO Modules

• Built-In Web Server
• Web HMI
• Support fot 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-7053/PET-7053/ET-7253/PET-7253 provides 16 dry 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.
