lamaPLC: Communication with Eastron Smart X96

The Smart X96-5 is a high accuracy multifunction power meter that is a traditional wired 1/5A current transformer operated meter. Configurable for 1p2w, 3p3w and 3p4w systems and hosting a vast range of measuring parameters such as Amps, Volts, Power, Power and Current Demand (Sliding and fix scale options), Power Factor, imported and exported kWh, Individual harmonics, Phase sequence and a phase summary page. It is one of the most user-friendly multifunction power meters in the market form installation to end client use.

It is typical in most installations that the current transformers are mounted on the left-hand side of the breaker so P1 is facing the correct way. However, it is also possible to mount the current transformer on the right-hand side with P2 facing the breaker. This is possible due to the meter having the option to reverse the flow to correct this type of application.

The SMART X96-5 requires mains voltage inputs and external current transformers in order to operate, it is self-supplied via a internal three phase transformer, this means if any of the phases fail the meter will remain powered and does not require an external auxiliary supply. The Smart X96-5 meter comes complete with RS485 Modbus RTU and dual pulsed outputs as standard.
