MONITORING RELAY CURRENT, 2XS0, 16A, 0-22kW

Multifunction current relay for current measurement and switching. Use in conjunction with bidirectional three-phase energy meters having two S0 outputs or an IR interface according to IEC 62056-21 standard. Can be used, for example, to switch a desired consumption device on and off (e.g., water heater) when solar panels produce sufficient electricity. Adjustable on/off threshold between 0-22 kW and adjustable on/off delay between 0-120 minutes. Use together with, for example, Eltakon's bidirectional energy meter:

• Serial No. 67 126 45 - DSZ15DZ-3x80A MID (with MID approval)
• Serial No. 67 126 47 - DSZ15DZE-3x80A (without MID approval)

• 1 normally open (NO) potential-free contact 16A/250V AC
• DX technology (neutral point switching)
• Standby power consumption only 0.6 watt
• S0-OUT terminals:
• These terminals allow chaining up to ten additional MFSR12DX-230V multifunction current relays, enabling the use of multiple different switching thresholds.
• The maximum cable length between two MFSR12DX-230V units is 10 meters.

Operation: Switch on relay contact 1-2:

When the set power value (?) of the energy supply is reached, the turn-on delay (AV) begins, which can be set between 0, 1, 3, 5, 10, 15, 30, 60, 90, 120 minutes using the rotary switch (AV). The red LED indicator below the rotary switch (AV) flashes as long as the AV time is active. After the AV time expires, the relay contact closes if the set power (kW) has not again dropped below the set switching threshold. The red TILA LED remains on as long as the relay contact is closed.

Switch off relay contact 1-2:

When the set power value (?) for energy consumption is reached, the turn-off delay (RV) begins, which can be set between 0, 1, 3, 5, 10, 15, 30, 60, 90, 120 minutes using the rotary switch (RV). The red LED indicator below the rotary switch (RV) flashes as long as the RV time is active. After the RV time expires, the relay contact opens if the set power (kW) has not again dropped below the set switching threshold. The red TILA LED is off whenever the relay contact is open.

Adjustments via rotary switches: Setting reference power switching threshold (kW grid ?).

The switching threshold at which the relay contact opens is set using the lower rotary switch (kW Grid ?). The adjustable power values are 0, 0.5, 1, 2, 3, 5, 7, 9, 11, 22 kW.

Setting generated power switching threshold (kW grid ?).

The switching threshold at which the relay contact closes is set using the lower rotary switch (kW Grid ?). The adjustable power values are 0, 0.5, 1, 2, 3, 5, 7, 9, 11, 22 kW.

S0 inputs, S01 (consumed electricity ?) and S02 (generated electricity ?).

The S0 pulses/kWh of the connected energy meter are set using the corresponding S01 and S02 rotary switches. The adjustable values are 10, 100, 200, 500, 800, 1000, 2000 Imp/kWh.

AIR input (OBIS codes according to IEC 62056-61).

Using the AIR BA rotary switch, you can select the appropriate operating mode.
