Additional Product Information

Relay outputs can directly switch 230V/16A AC mains, dry contact inputs can be used e.g. for buttons. The device features a full RS-232/485 serial port for connecting e.g. a RFID or barcode reader. IP Relay is fully certified to control 110/230V and fits on a DIN rail.

Ethernet IO can be controlled over the Web, Modbus/TCP or Telnet NVT.

When the IP Relay is connected to a PC over the LAN, it can work as a serial converter that connects its RS-232 over Ethernet to a Virtual Serial Port (VSP). HW group offers HW VSP – a free virtual serial port application that supports up to 100 remote serial ports (support includes Windows 7 and x64 systems). Full RS-232 serial port controls all 9 signals, RxD, TxD, GND, CTS, RTS, DSR, DTR, RI, CD (115,200 Bd).

Typical applications include remote power control, opening a remote gate over a LAN (relay output) and connecting a RFID card reader (RS-232).

Free HW VSP Software:

Virtual serial port for Windows (NT service, x64 systems). Supports up to 100 remote serial ports. HW VSP is the world's most popular virtual serial port for Windows! HWg IPRC cmd utility: Command-line utility for remote control of outputs (Windows and Linux)
