The LCD module may be ordered with a 5x1 or 4x10 register for self-contained
meters, and a 5xTR or 4xTR register for transformer-rated meters.
The kWh only version of the CENTRON provides very accurate measurement for
energy accumulation for today’s needs, but also provides a platform for easy
upgrade to higher functionality in the future.
Physical Description
The CENTRON Personality Modules snap into the meter register mounting
brackets to ease installation of the board.
The LCD module is connected to the metrology board using the board-to-board
connector. The following information is sent to the LCD module from the
metrology board:
• Line voltage
• Reference voltage
• Energy flow direction
• Energy pulse data
• Line frequency
A connector is located at the 12 o'clock position behind the LCD for resetting the
energy register. This is done using the ZRO-C2A Resetter.
