Contactor Relay AF contactor relays are AC/DC operated AF09-AF38 contactor relays include an electronic coil interface accepting a wide control voltage Ucmin - Ucmax. Only four coils cover control voltages 24 → 500 Vac or 20 → 500 Vdc AF..Z contactor relays equipped with a Z coil type allow direct control by 24 Vdc, 500 mA PLC output and obtain a reduced holding coil consumption AF.Z contactor relay withstand short dips and voltage interruptions (SEMI F47 compliance) AF contactor relay have built in surge protection and does not require any additional surge suppressors. The contactor relays have mechanically-linked contact elements compliant with Annex L of IEC 609947-5-1 and include the "mechanically Linked" symbol on their side Standards IEC 60947-5-1 and EN 60947-5-1, UL 508, CSA C22.2 N 14
