The front three-point fixed installation of the R board conforms to the appearance and installation dimensions of BS 7856 and DIN 43857 standards.

R can choose between a 6-digit LED digital display or a 7-digit LCD display.

R can choose one meter, one card, and can be recharged repeatedly through a PC with an IC card programmer.

R can choose to support both repeatable recharge cards and one-time recharge cards, which can be recharged online with a PC through an IC card programmer or separately offline.

R can choose to have built-in far-infrared communication module and RS485 communication module for meter reading, remote cost control, and system parameter settings.

There are two options for R: keyboard based IC card programmer and regular IC card programmer.

R has IC card data encryption and anti-counterfeiting protection functions.

R adopts electricity based prepayment, and can choose amount based prepayment (please specify when placing the order).

The standard configuration of the R prepaid management system software adopts a standalone version, and a network version can be selected (please specify when ordering).

R has load control, automatic fault detection, and indication functions. The standard configuration does not have a lid opening detection function, and the lid opening power-off function can be selected (please specify when ordering).

The R configuration has a polarized passive power pulse output port that complies with IEC 62053-31 and DIN 43864 standards.

The R LED indicates the power status (green), power pulse signal (red), and load current flow direction (yellow) respectively.

R automatically detects the direction of load current flow, and when the yellow LED displays, it represents the opposite direction of current flow.

Single directional measurement of single-phase two-wire active energy consumption, independent of the direction of load current flow, in accordance with IEC 62053-21 standard.

R is directly connected and has two wiring options: 1A type and 1B type.

R has two options: extended terminal cover and short terminal cover.
