PCB Mounting Relays
2-pole/4-pole relay RZDR-E□D□C (Large-Capacity Type)
▼Features
◼ These relays are reliable in a wide range of applications, from small current circuits at signal level to power circuits for switching inductive loads.
◼ With their wide range of current capacities, inductive loads can be opened and closed directly when used with the signal output of a PLC.
◼ For PCB mounting Bestact relays with built-in Bestact (R25) contacts, two contact output and four contact output can be selected widening the range of sequence control.
◼ Flow soldering is supported.
◼ These relays have the vibration and shock characteristics required for use as railway relays.
◼ These relays can be used in a wide range of temperatures and can cope with battery voltage fluctuations in railway vehicles.
