PCB Mounting Relays
2-pole relay RIW (Medium-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.
◼ The wide range of current capacity allows direct switching of inductive loads when used with PLC signal output.
◼ The low power consumption of the coil reduces the temperature rise in the switchboard.
◼ Flow soldering is supported.
◼ For 2-contact models, either 1NO1NC contact or 2NO contact can be selected for economical operation.
