PCB Mounting Relays
3-pole relay RZDR-G□D□C (Medium-Capacity Type)
▼Features
◼ These relays offer high reliability in a wide range of applications, from small current circuits at signal level to power supply circuits for switching inductive loads.
◼ Thanks to their ample current capacity, they can also be used in conjunction with the signal output of a PLC to directly open and close inductive loads.
◼ Bestact relays for board mounting with built-in Bestact (R25) contacts are available with 3 contact outputs, expanding the range of sequence control.
◼ Flow soldering is supported.
◼ They have the vibration and shock characteristics required for railway applications.
◼ They can also be used over a wide temperature range and can cope with battery voltage fluctuations in rail vehicles.
