NOVUS DIGIRAIL Model 4C
The DigiRail line of smart transmitters with Modbus RTU comunication interface provide a simple way for integrating analog or digital signals to supervisory systems. Featuring up to two universal input analog signal channels they are the most economical way to deliver analog inputs to PLC´s and SCADAsystems. The input signals are isolated from power thus protecting the electrical instruments by eliminating ground loop effects. This reduces substantially the undesirable interferences and instabilities in sensor measurements. DigiRail can be easily configured and calibrated via the digital interface by using the Windows based Digiconfig software.
