The present disclosure relates to a relay module including a control input for combined control and power supply of the relay module with alternating voltage. A fixed voltage controller of the relay module generates a fixed voltage after rectification of the alternating voltage or a portion of the alternating voltage. A comparator is operated by the fixed voltage and derives a reference voltage from the fixed voltage. The comparator compares a rectified and smoothed portion of the alternating voltage with the reference voltage.
