Product information "ET-7217RMS Ethernet I/O Module, 8-ch True RMS AI, 4-ch DO, 2-port Switch"
The ET-7217RMS converts AC input signals into their True RMS DC equivalents, so engineers can read the RMS value of complex waveforms over Ethernet. Each of its 8 differential analogue channels can be configured individually, with an input range from +150 mVrms to +10 Vrms.
Four isolated open-collector digital outputs are built in, with programmable power-on and safe values. The 2-port 10/100 Base-TX switch with LAN bypass supports daisy-chain topologies, and the module communicates via Modbus TCP and Modbus UDP.
The module includes a built-in web server with web HMI, access control by ID, password and IP filter, and dual watchdog protection. It is DIN-rail mounted and specified for an operating temperature of -25 ~ +75 °C.
Applications
- Monitoring AC signal levels as True RMS DC values
- Daisy-chained Ethernet I/O networks with Modbus TCP or Modbus UDP host systems
- Remote acquisition and switching in DIN-rail control cabinets
