Wireless energy meter transmitter module 12V DC. Only 0.5 watt standby loss. 1 NO contact potential free 4A/250V

Wireless energy meter transmitter module for connection to S0 interface of many single-phase energy meters and three-phase energy meters. Only 0.5 watt standby loss. With load shedding relay 1 NO contact potential free 4A/250V and with exchangeable antenna. If required, a wireless antenna FA250 or FAG55E- can be connected. Modular device for DIN-EN 60715 TH35 rail mounting. 2 modules = 36mm wide, 58mm deep. The energy meter transmitter module FSS12 evaluates the signals of the S0 interface of an electricity meter and sends wireless telegrams with the consumption and the meter reading to the Eltako wire­less building for evaluation with the Professional Smart Home Controller. On three-phase energy meters, the data sent includes normal rate (HT) or off-peak (NT) energy tariff data, provided the E1/E2 terminals on the three-phase energy meter are connected to E1/E2 on the FSS12. With adjustable pulse rate. The 12V DC supply voltage is powered at 12W by a switch mode power supply unit SNT12-230V/12V DC-1A that is only 1 pitch unit wide. If the relay of the FSS12 is switched on, a power of 0.6 watts is required. The setting and display screen is subdivided into 3 fields: Field 1: The normal display is the unit of the meter reading currently displayed in Field 3. This alternates every 4 seconds with either kilowatt hours kWh (KWH in display) or megawatt hours MWh (MWH in display). The display in Field 1 is supplemented by a + sign after the reading to indicate that the off-peak tariff rate is applied to E1/E2. Field 2: Instantaneous values of energy consumption (active power) in watt (W) or kilowatt (kW). The left-pointing arrow in Field 1 indicates an automatic switchover from 0 to 99W to 0.1 to 65kW. Field 3: The meter reading is the normal display. Every 4 seconds the display alternates between 3 whole number and 1 decimal point (from 0.1 to 999.9kWh) and 1 or max 3 whole numbers (from 0 to 999MWh). At freely chosen pulse rates whose last digit is not 0, the meter reading is displayed without decimal place in increments of 1kWh. Wireless telegrams: Maximum every 130 seconds a performance telegram will be sent and the display will be updated. Otherwise a telegram will be sent within 20 seconds if the power changed by at least 10%. A switchover from HT to NT is transmitted immediately in the same way as a meter reading change. A full telegram comprising meter reading HT, meter reading NT and power is transmitted 20 seconds after the power supply is switched on and then every 10 minutes. Settings with the MODE and SET buttons according to the operating instructions.
