99.80.9.024.90

The 99.80.9.024.90 is a standard polarity LED + Freewheeling Diode Module. The module with LED and free-wheeling diode must be used only with DC. The negative cut-off voltage of the relay coil through the free wheeling diode shorted. The release time of the relay shall be extended by a factor of approximately 3. If this extension of the fall time is not desirable, so is a varistor or to choose an RC module.
