Multifunction current relay for bidirectional three-phase meters with two S0 outputs or IR interface according to IEC 62056-21. 1 NO contact potential free 16A/250V AC, with DX technology. Standby loss 0.6 watt only. Modular device for DIN-EN 60715 TH35 rail mounting. 3 modules = 54mm wide, 58mm deep. This current relay either evaluates the data of a balancing bidirectional three-phase meter, e.g. DSZ15DZ-3x80A with two S0 interfaces, or that of an electronic household meter (eHZ-EDL) with IR interface according to IEC 62056-21 and SML protocol version 1. The data for the power consumed (arrow right) and the power supplied (arrow left) are recorded, evaluated and a relay contact is switched on or off according to the settings. With the patented Eltako Duplex technology (DX) the normally potential-free contact can still switch in zero passage when switching 230V AC 50Hz and therefore drastically reduce wear. Simply connect the neutral conductor to the terminal (N) for this. This results in an standby consumption of only 0.1 watt. Supply voltage 230V. If the supply voltage fails, the switching status is retained. When the supply voltage returns, it is defined switched off. S0 inputs S01 (consumed power arrow right) and S02 (delivered power arrow left). The S0 pulses/kWh of the electricity meter used are set with the respective rotary switch. Adjustable values are 10, 100, 200, 500, 800, 1000, 2000 Imp/kWh. AIR input (OBIS codes according to IEC 62056-61). With the rotary switch AIR (BA) you can choose between the following operating modes: 1: Purchase totalizer (1.8.0) and reference power on channel 1, supply totalizer (2.8.0) and supply power on channel 2. 2: Purchase of tariff 1 (1.8.1) and tariff 2 (1.8.2) and reference power on channel 1, supply of tariff 1 (2.8.1) and tariff 2 (2.8.2) and supply of power on channel 2. 3: Import tariff 1 (1.8.1) and tariff 2 (1.8.2) and import power on channel 1, supply totalizer (2.8.0) and supply power on channel 2. 4: Purchase totalizer (1.8.0) and reference power on channel 1, supply tariff 1 (2.8.1) and tariff 2 (2.8.2) and supply power on channel 2. If no AIR is used, the rotary switch must be set to the right stop. The connection is made using an IR scanner AIR. The IR scanner is fixed with its fastening magnet over the IR output of the meter and connected with its connection cable to the Rx, GND and +12 V terminals. Setting the switching threshold for the reference power (kW grid arrow right). The switching threshold at which the relay should switch off is set with the rotary switch (kW Grid arrow right). The adjustable values for the power are 0, 0.5, 1, 2, 3, 5, 7, 9, 11, 22kW. Setting the switching threshold for the delivery power (kW grid arrow left). The switching threshold at which the relay should switch on is set with the rotary switch (kW Grid arrow left). The adjustable values for the power are 0.2, 0.5, 1, 2, 3, 5, 7, 9, 11, 22kW. Functionality: Turn on relay contact 1-2: When the set power for the energy supply (arrow left) is reached, the response delay time (AV) begins, which can be set between 0, 1, 3, 5, 10, 15, 30, 60, 90, 120 minutes with the rotary switch (AV). The red LED behind the rotary switch (AV) flashes as long as the AV time is running. At the end of the AV time, the relay contact switches on if the power (kW) has not fallen below the set switching threshold again. The red STATUS LED lights up as long as the relay contact is closed. Switching off relay contact 1-2: When the set power for the energy consumption (arrow right) is reached, the off-delay time (RV) begins, which can be set between 0, 1, 3, 5, 10, 15, 30, 60, 90, 120 minutes with the rotary switch (RV). The red LED behind the rotary switch (RV) flashes as long as the RV time is running. At the end of the RV time, the relay contact switches off if the power (kW) has not fallen below the set switching threshold again. The red STATUS LED goes out when the relay contact is open.
