Can I connect the contactor to a GSM outlet?

Good afternoon. I have a modular contactor ABB EN20-20 (20A AC1) with a 24AC control coil. I want to apply to turn on remotely converters. The control will be switched on by a current of 24VDC (i.e. constant) from a GSM outlet. Is it possible?

    If the coil is designed for alternating current, then it cannot be turned on for direct current. The contactor will not work correctly, the coil will most likely burn out, since the resistance of the coils to AC and DC is different. Experiment by adding resistance, but it’s better not to. If you want the contactor to work normally, get a contactor whose control coil is powered by direct current.
