The new IP relay HWg-ER02b replacing previous model. New is the Modbus/TCP protocol support, WEB config and two DI (Digital Inputs) for external dry contacts.
Ethernet relay, DIN rail, Web interface. Features 2x DI (dry contact input), full RS-232/485 serial port, and 2x DO (relay output, 230V/16A).
Controlled over the web or Modbus/TCP. Two IP relays connected back-to-back can extend (“tunnel”) the serial port and I/O over a LAN.
Usage examples
- Connecting a RFID reader over a LAN + remote reset of associated equipment
- Connecting a barcode reader over the Ethernet + controlling DI and DO in an application
- Remote UPS or diesel generator monitoring with RS-232 monitoring + remote start / test over the I/O
- Vending machines
- Security alarms
- Access control systems
- Barcode scanners in combination with LAN relay (remote I/O)
