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.

Note:
1. The contact performance specifications refer to the built-in contacts.
2. The rated operational current indicates the current value to be used under the rated operational voltage and specified conditions (make and break current, switching frequency, and electrical endurance).
For 240VAC: The setting is based on 10× make (cosφ = 0.6–0.7) and 1× break (cosφ = 0.3–0.4). A rated operational current of 1A means 10A for making and 1A for breaking. For 115VDC: The setting is based on 1× make and 1× break, specified for inductive loads (L/R = 40ms).
3. The operating time of NO contact and NC contact may overlap.
4. Time characteristics are values measured at an ambient temperature of +20℃ with the coil energized at its rated voltage.
5. Temperature characteristics are values under conditions without freezing or condensation.
