Plug-in Relays
3-pole relay RB3P-G□D□C (Medium-Capacity Type)
▼Features
◼ These Plug-in type 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.
◼ This plug-in type relays with built-in Bestact (R25) contacts are available in a 3-contact configuration with a choice of 2NO1NC or 3NO contacts, expanding the range of sequence control.
◼ These relays have the vibration and shock characteristics required for railway applications.
◼ These relays can be used in a wide range of temperatures and can cope with battery voltage fluctuations in rail vehicles.
