Converters
to modbus RTU
Converters to modbus RTU
Usually, one controller is not enough to control large ventilation systems, while the controller doesn't have enough temperature or analogue inputs, analogue or relay outputs. Ouman has successfully solved this problem by developing universal Inputs to Modbus RTU converter, analogue outputs to Modbus RTU converter and other converters. We can create the perfect solution for your ventilation system using one freely programmable controller and by solution needed converters. You could control and monitor your system online via the internet without any problem, just you need to install Modbus RTU to TCP converter. Then you will have a local FTP server, or you could use Ouman cloud (Ouman Flexiot).
