Notes

Note

To prevent damaging the gold layer, 30 V switching voltages and 50 mA currents must not be exceeded. Higher switching power eventually evaporates the gold layer. The resulting deposits in the housing may reduce service life.To protect the relay coils and contacts, inductive loads must be dampened with an effective protection circuit.
