• Bridge between third-party Modbus devices and TWSN radio network
    (bridge function between TWSN gateway and Modbus devices)
  • Modbus/RTU protocol usage on physical layer RS232
  • TWSN repeater function
  • Powered with 48 Vdc mains
  • External radio antenna

TWSN-232 is a radio device powered with 48 Vdc mains with function of connecting, via the TWSN radio network,
one or more third-party Modbus devices having RS232 interface to the TWSN gateway.

TWSN-232 allows to exchange information with Modbus devices without any wired connection; consequently it works as a bridge, creating a wireless connection between TWSN gateway and Modbus devices.

The device can also work as a repeater to other radio devices.
