Amp and Volt Meter (M350)

Three Phase Ammeter and Voltmeter

M530

Easy to Install with Bright Displays and Simple Communications Setup

All of the primary settings can be programmed using the front display buttons. Simple and advanced settings are easily configured through the Ethernet service port. Pre-set register/point sets and display screens coupled with the universal power supply and universal wiring make it easy to go from out-of-the-box to up-and-running in no time.

Display

  • 3-line at once, easy-to-read, long-life LED displays that can be read from far away in all substation conditions including bright sunlight
  • Ultimate precision with five digits per line
  • Instant recognition of the displayed function from the trademark alphanumeric display of engineering units
  • Easy setup and scrolling from front display with “Touch-Sense” buttons

Communications

  • DNP3 or Modbus protocol available via configurable RS-232/RS-485 serial port
  • No need for PC software – RJ45 service port provides access to web server in the instrument so meters can be interfaced with just a web browser for viewing and configuration
  • Available Ethernet to provide DNP3 or Modbus TCP/IP protocol operability
  • Optional fiber port that replaces standard Ethernet service port and includes Modbus and DNP3 Ethernet protocol support
  • Optional transducer output to interface with older generation RTUs

Measurements

  • Either 3-phase voltage including avg/min/max voltage or 3-phase amperes with amp demand
  • Accuracy is 0.1% of reading for volts and amps
  • Updates every 100ms

Built for the Substation

  • Wide-range universal power supply for all substation installations
  • Rugged aluminum case
  • Reduce inventory cost as one voltmeter model
  • Covers all voltage wiring options
  • Easy to mount with standard 4” round meter

Applications

  • Digital front-end to SCADA systems
  • Intelligent Electronic Device (IED) interfacing to RTUs and PLCs
  • Local indication of substation conditions
  • Plant equipment monitoring
  • Line monitoring

IP Address Identity Tool

Inverse Address Recognition Protocol (InARP) is a software utility program available for 50 Series SCADA meters that requests the IP address for a specific MAC address on an Ethernet network. It can also scan for a range of MAC addresses and print the IP address for any devices which respond. The utility requires the WinPcap and Packet libraries which are bundled in the WinPcap “Installer for Windows,” downloadable from www.winpcap.org.  Installation requires  Administrator privileges.  Download the application here.
