RS Relays

Coil data

  • Operating characteristics such as 'Operate voltage' and 'Release voltage' are influenced by mounting conditions, ambient temperature, etc.
    Therefore, please use the relay within ±5% of rated coil voltage.
  • 'Initial' means the condition of products at the time of delivery.
