  • Zero voltage turn-on
  • Long service life - capable of millions of cycles
These high-reliability solid-state relays offer years of troubles-free service and millions of cycles - no moving parts to wear out. The relay action is SPST, normally open. The relay closes with a signal from your controller. A zero voltage turn-on eliminates RTI; the relays produce virtually no electrical noise.
Choose a DC-input relay for your temperature controller having a voltage pulse output. Select an AC-input relay for your temperature controller having a mechanical relay output. Order relays from table below (wiring not included).
Vertically mount the relays on heat sinks to dissipate the heat generated when relays are used at their rated output. Relays must be derated if used without a heat sink or at elevated temperatures. Order heat sinks and thermal transfer compound separately.FEATURES
  • 10-75 amps, 330 Vac max
  • 50-75 amps, 660 Vac max
  • Single phase, zero crossing
  • LED input indicator
  • Clear safety cover included
  • Panel mount
  • DC and AC input versions
  • Superior surge survival
  • EN60947-4-3 compliant
  • UL recognized, CSA listed

Note: Relays do not come with overload protection—always wire a fuse into the load circuit.
