INPUTS -E 404-1B The wires carrying the current must pass through the correspondent hole of the device. The wire direction has no influence. The 3phase voltage is connected to the pins 20, 22, 24. Input Resistance = 800 k REMARK 4 Connect to pin 24 the phase used to measure the current (amperometric phase). OUTPUTS E 404-1B 1 change over Relay -5A(NO) 3A(NC)-230 Vac resistive load A1 Relay 6-4 NC Device not supplied 6-5 NO or in alarm REMARK 5: The application of RC groups on the contactors coils is highly recommended. ANALOG OUTPUT of E 404-1B Outgoing from pins 27 and 26: 10 Vdc (full scale) DC voltage, proportional to the power + on pin 27 (1mA max). In order to enter the power value range valid for the device triggering, the voltage analog output must be higher than 1,0 V, equivalent to step 10 in the set point front setting.
