The RI-D384-C is a DIN Rail Mounted Multifunction energy meter showing measuring parameters that are required for successfully carrying out energy efficiency projects and monitoring the electrical distribution in low and medium voltage networks. (1 and 3-phase systems with a neutral conductor). Ideal for both energy managers and electrical engineers.

Easy To Use
Thanks to its large backlit LCD display the RI-D384-C provides clear readings and easy access via the push buttons.

They directly display a number of multi-measurement and metering values such as :
+/- kWh (kilowatt) , +/- kvarh, kVah, I (Current), U (Potential Energy), V (Voltage), F (Frequency), P (Active Power), Q (Reactive Power), S (Apparent Power), PF (Power Factor).

Communications
The RI-D384-C standard communication options are : RS485 Modbus RTU.

Having a RS485 interface with a Modbus RTU protocol enables extremely cost-efficient networking. It features simple topology configuration and a lack of sensitivity to EMC interference. Communication between the sender and the recipient takes place on a wired basis via a sheathed, twisted pair cable. The Modbus communication can be transferred to any control system such as BMS, SCADA. PLC systems using the Modbus registers.
