Applications and usage:
- Link two buttons/switches to a SW application.
- Connect your RS-232 devices to your LAN – barcode / RFID scanners, serial printers, displays.
- The remote relay output can, for example, open a door, turn on a horn, or disconnect power. It can be used also as web relay.
- I/O can be controlled over Modbus/TCP from any SCADA system, independently of the serial line.
- Remote power switch (power control) can switch 230/110V AC directly.
- 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)
