The OMEGA® SSRLDUAL Series
solid-state relays are 2 totally
independent AC output relays in
a single standard panel mount
package. They utilize OMEGA’s
inverse-parallel SCR output design
with integral dV/dt snubber circuity
to provide protection against false
triggering by limiting the rate of rise
of most voltage transients to within
acceptable limits. Zero volt turn-on
and zero current turn-off of the load
being switched substantially
reduces EMI and RFI.
