Discontinuation of LON meter recording module U1660-V002 ». The LON additional component is used for the decentralized recording of measuring points in the Energy Control System. The meter recording module U1660 processes data from up to 8 energy meters with pulse output (S0) or potential-free contact. The active inputs do not require an additional power supply and thus minimize the wiring effort. The additional component extends the functionality of the summator U1601, the micro summator U1602 and the mini summator U1603 to include external inputs via the LON interface. 8 active S0 pulse inputs, required pulse duration > 100 msStatus display via LEDFTT-10A transceiver (78 kBit/s)Standard network variable for energy, instantaneous power and statusStatus display via LED.
