Power Measurement Ltd. (Victoria, BC, Canada) introduced three new options for its ION® 7550 and ION 7650 intelligent energy meters: an ION 7550 remote terminal unit (RTU) option for monitoring multiple utilities, a non-intrusive current transformer option for quick installation without de-energizing circuits, and a low-voltage dc power option for running a meter from substation or genset battery supplies.
The RTU option converts the ION 7550 energy meter into an effective solution for combined metering of utilities. Using I/O points and Modbus Master support, the meter inputs pulses, analog signals and data from other meters and transducers. The ION 7550 RTU offers data and sequence-of-events logging, GPS time synchronization and web-enabled communications options for collecting, storing and delivering information over public or private networks to energy management or automation systems for later analysis.
The low-voltage power supply option enables either the ION 7550 or ION 7650 meter to be powered from an auxiliary supply, using 20 Vdc to 60 Vdc. The RTU current transformer and low-voltage power supply options are available now.
