The KET-MES-610 is a pulse counter that connects to the standard ES (signal output) interface of the electricity meters, equipped with 6 digital inputs with signal repeater for dry contacts: 2 for active and reactive energy withdrawn; 2 for active and reactive energy fed in; 2 for tariff bands.
It is equipped with an RS485 interface with ModBUS RTU protocol compatible with the ModBUS bridge/Master KET-RMB-211 and X-Monitor gateways.

Maximum flexibility of power supply, direct from the mains or low voltage, both DC and AC.

Format suitable for mounting in control cabinet on DIN rail.
The internal F-RAM memory for continuous saving of the meters allows data storage even in the event of sudden power failure.

The KET-MES-610 allows K and C factors to be entered for the withdrawal and feed-in meters, so that it calculates in real time the kWh of active and reactive energy and the instantaneous powers for each meter. In addition, if the contacts for the F1, F2 and F3 bands are active, it sums the active energy withdrawn on three separate meters.
These features make the KET-MES-610 the ideal instrument for UVAC, UVAP and UVAM installations for the MSD.
