The Solexy MODBUS RTU radiomodem is a VHF/UHF high quality 500 mW radiomodem operating on 12,5 or 25 kHz channels available in 169 MHz and 868 MHz band in according to European Decision 2005/928/CE.

These products are develop in order to be a licence free device.

The Solexy MODBUS RTU radiomodems are supply complete with 4 digital input, 2 digital output plus 2 analog input and 2 analog output 4-20 mA that allows to has an Modbus RTU node. The RS485 interface permit also the connection up to 4 Modbus module.

The SWA and SWS anclosure thanks to its rugged construction combined to Atex and IECEx certificate achieves to have an Modbus RTU data transmission in classified area Ex.

Wide range of transmission option

Mirror (point to point), Modbus RTU, Modbus multi master and standard Radiomodem option completely transparent to the user also in case of complex route

Modbus RTU

The Solexy MODBUS RTU radiomodem can be used on all Modbus RTU application

Modbus RTU Node

4 PNP digital input combinet to 2 relay output plus 2 analg input and 2 optoisolated analog output 4-20 mA allows to use the radiomodem as a complete Modbus RTU node.
