Operation
Spike Protectors
R-K Spike Protectors are applied to control and
instrumentation loop circuits where transient
electrical voltages can cause malfunctions
or damage to solid state controls or process
systems. The Spike Protectors are designed to
control voltage spikes within a tolerable level
while minimizing any effect to the analog control signals. The SPs are typically connected in
parallel with the signal leads and ground at the
controller. The varistor combinations allow the
excessive voltage spikes to dissipate line to
line and line to ground.
