NR30 - Rail Mounted Power Network Meter
NR30IoT - Rail Mounted Power Network Meter for IoT Applications
Measurement of 54 power network parameters and current and voltage harmonics up to 63rd, in 1-phase 2-wire or 3-phase 3 or 4-wire balanced and unbalanced systems.
➜ The MQTT protocol is ideal for communication in distributed acquisition systems data - iot applications (NR30IoT)
➜ High accuracy class (0.2s for active energy)
➜ Backlit LCD screen fully configurable by a user (22 views, 3 parameters in each)
➜ For direct (up to 63A) and indirect measurement (x/1A or x/5A)
➜ Indications considering values of programmed ratios.
➜ Memory of minimum and maximum values
➜ 2 configurable alarm outputs
➜ Optional: with an additional module of analogue outputs S4AO (max. 4 current or voltage outputs)
➜ Digital output RS-485 - MODBUS protocol
➜ Archiving of up to 32 measured parameters in the internal memory 8GB
➜ Modern and user-friendly ethernet interface 10/100 BASE-T:
• protocol: MODBUS TCP/iP, HTTP, FTP
• protocol: MQTT (NR30IoT)
• services: www server, ftp server, DHCP client
➜ Programming of parameters through usb using free econ software • Battery backup RTC
➜ Modular housing for S-rail according to EN 62208 (the meter has a width of 6 modules)
➜ Supervisory relay mode for alarm outputs (NR30 and NR30IoT)
➜ MQTT protocol (for NR30)
