Polarized Relays

The Polarized RIB series is equivalent to the standard RIB series except for the coil which is polarized. We are currently offering nine polarized relays, most of which have a similar non-polarized counterpart. The “FA” in the model name stands for Fire Alarm. These relays are designed for operation in systems that require supervision from controllers and utilize end-of-line resistors. The relay can also be operated from A/C voltage (non-polarized) if desired.
