Communication with Host

This latest generation of revenue meters supports the Modbus protocol over the RS485 interface for remote auto meter reading, some units even have a built-in relay for remote power disconnection and restoration

Pass-through and external CT wiring

Load Wiring

Pass-through: The live wire of the load is directly connected into the meter, this type of connection is limited to 80 amperes.

External CT: For loads greater than 80 amperes, external CTs are used. The load is passed through the primary, while the secondary 5A output of the CT is connected to the meter.

Remote Display Unit

Since every bit of floor space in a stall is precious, the meter is installed in an out the way place like the ceiling, hence the need for a separate display unit to show the meter reading.
