Limit value switch for frequency (sinusoidal signal)
Limit value switches of type RFS5 monitor electrical measured variables. The integrated relay switches when the actual value present reaches the set target value. Open-circuit devices can also be equipped with a self-latching feature as an option. Its compact and robust design, as well as the relevant shipbuilding approvals, make this product ideal for marine applications.
