ELR W 3/9-400 ELR W 3/9-500 Electronic Reversing-Load Relay for 3-Phase Networks Data Sheet 01/2005 Features Electronic Reversing-Load Relay ELR W 3/9... ELR W 3/9... electronic reversing-load relays are the practical and user-friendly further development of electronic load relays for 3-phase networks. The ELR W 3/9... is the fully electronic alternative to mechanical contactors. It features a compact design and low control power. A further advantage is the highquality, safe screw connection technology. These components feature high switching frequencies, virtually unlimited service life, no spark interference, and completely silent switching at zero voltage crossing. The compact, DIN rail-mountable modules meet all the requirements of an electronic reversing contactor circuit that has been designed specifically for industrial applications. Both the interlocking of control inputs and the complete wiring of the load contacts are incorporated in the device. Costly locking switches and contact wiring are thus a thing of the past. In accordance with DIN VDE 0110 and DIN VDE 0636, a conductor cross section of 1.5 mm2 (16 AWG), which must be fitted with one fuse each (10 A slow-blow as mains protection), is required to connect the electronic load relay to the 3-phase network. Cabling has been reduced to an absolute minimum. Only the following must be applied: – Control voltage, supply voltage input and output – 3-phase load The status is clearly indicated by separate LEDs for "right rotation", "left rotation", "operating voltage" or "impermissible control". A short circuit between two phases at the moment of switching is prevented by the integrated delay between the control pulse and the load control. RCV protective circuits on the output side reduce voltage peaks that occur in the load circuit to a safe level and prevent damage to the output electronics. 5104778_03_en 1 ELR W 3/9-400/ELR W 3/9-500 Technical Data Input Data (Input) Operating voltage UB Maximum current consumption Control voltage right/left Input current right/left Right rotation/left rotation switchover time (switch-on time) Input wiring 1 ELR W 3/9-400 ELR W 3/9-500 24 V DC +25%; -20%1 40 mA 24 V DC +25%; -20%1 6 mA, approximately 20 ms LED, diode for protection against polarity reversal, surge protection The operating voltage and control voltage inputs must be operated with power supply modules according to DIN 19240 (maximum 5% residual ripple). To prevent the inductive or capacitive coupling of disturbing pulses in long control cables, we recommend the use of shielded cables.
