    ... This method is valid only for Resistive Loads, and is an approximation only; keeping in mind the limitations mentioned above. Example: A designer is working with a 55 volt DC system and has a relay rated at 10 amps resistive at 28 volts DC. What is the maximum current that can be switched at 55 Vdc. ...

    ... Most relay parameters are specified as maximum values over the rated temperature range of the specific relay. Users often find that key parameters differ significantly at ambient temperature (20-25°C) and sometimes fall into the trap of specifying their system around these ambient parameters. Additionally the actual temperature experienced by the relay can be far in excess of existing ambient temperatures due to the heat generated by the coil current and the contact load ...

    ... Calculation of coil temperature rise when R initial and R final are known: Delta T = (234 Delta T = Temperature rise (° Initial temperature (° Initial resistance (Ohms Final resistance (Ohms Temperature can also be found by making the R coefficient of correction graph in Fig. 2, and then finding the corresponding temperature. ...

    ... The faster the switch-off, the higher the induced voltage. All coil suppression networks are based on a reduction of speed of current decay. This reduction may also slow down the opening of contacts, adversly effecting contact life and reliability. Therefore very important to have a clear understanding of these phenomena when designing a coil suppression circuitry ...

    ... R = coil resistance in kiloOhms C = capacitance in microFarads The series resistor must be between 0.5 and 1 times the coil resistance. Special consideration must be taken for the capacitor inrush current in the case of a low resistance coil. The record shown opposite is performed on the same relay as above. The operation time becomes: - time to start the movement 2 ...

  • Page 11

    ... At the opening time the current becomes constant as a result of practically zero opening speed. Due to this kind of behavior, this type of suppression must be avoided for power relays. For small relays which have to switch low currents of less than 0.2 A, degradation of life is not that significant and the method may be acceptable. ...

    ... The lower curve on the opposite record demonstrates those characteristics. Voltage limitation occurs at 42V. The two voltages spikes generated by internal movement are at lower levels than zener conduction result, no current is recycled in the coil. The opening time phases are as follows: - time to start the movement 2 ...
