RL-485-01 is a device designed to provide 3-phase voltage and frequency information to devices such as RTU and PLC, produced as an alternative to devices that perform voltage monitoring, breaker opening - closing operations in LV networks. There are 3 dry contact outputs and 4 digital inputs to receive feedback on the device. It has a simple use compared to its equivalents and can be connected to SCADA systems with the RS-485 port on it.
