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.
