WIRELESS DEVICE BRIDGE MODBUS/RTU
- 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.
