Switches for frequency

Limit value switch for frequency (sinusoidal signal)

RFG5

Limit value switch RFG5

  • Limit value switch for frequency input sinusoidal signal
  • Simple application; for rough environments
  • Limit value freely adjustable by drum scale
  • Open-circuit or closed-circuit devices available
  • Compact and robust construction
  • Operating status indication by integrated LED

Description

Limit value switches of type RFG5 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.
