W A T L O WPower ControllersE-SAFE ® RELAYThe E-SAFE ® mercury-free relay fromWatlow provides reliable and accuratepower switching for plasticsprocessing applications.This relay can exceed the performanceof typical mercury relays while fittingwithin the same footprint. The E-SAFERELAY bridges the gap betweenmercury displacement relays (MDRs)and solid state relays (SSRs) byproviding superior power switching ina non-mercury solution at a lower cost.This mercury-free relay also provideslonger contact life and higherperformance than typical mechanicalrelays used in equipment.The E-SAFE RELAY eliminatesmercury, reduces arcing and electricalnoise and provides processors with anexcellent solution for equipment powerswitching. The absence of mercury inthe E-SAFE RELAY reduces toxic metalhazards in processing environments.Performance Capabilities• Up to 40 amps• 240 VÅ(ac)Features and BenefitsHigh current transientsuppression• High reliability• Extended contact life• Low electrical noise• Outperforms mechanical contactorsCompact size• Fits footprint of definite purposerelays and most 30 to 50 ampmercury relays• Easily retrofittableEnvironmentally safer thanmercury contactors• Eliminates toxic waste (mercury)from the application environmentand disposal from failed mercurycontactorsSpecifications• Output rating: from 20A to 40Amaximum resistive load at-30 to 55°C (-22 to 130°F)• Maximum power switchingvoltage: 208/240VÅ(ac),three pole• Coil voltage: 24VÅ(ac),120VÅ(ac) and 220VÅ(ac)• Maximum operating ambienttemperature: 55°C (130°F)• Maximum cycle rate: 30 cyclesper minuteControl Mode• Zero cross switching output• Form A outputs, without arcing• Cycle rate: 30 cycles per minute,maximumInput Command Signal• 24VÅ(ac) (+10 / -15 percent),120VÅ(ac) (+10 / -10 percent)220VÅ(ac) (+10 / -15 percent)• 50/60Hz, less than 9VANote: Do not place an R/C snubber(filter) on the E-SAFE RELAYinput <strong>com</strong>mand signal.Output Rating• 20A to 40A max. per pole into aresistive load• 208/240VÅ(ac), 50/60Hz, eachpole• Three poleOperating Life• 1,000,000 switching cycles atmax. ratingWeight/Dimensions• Weight: 0.560 kg (1.25 lbs.)• 96.0 mm (3.78 in.) high x82.3 mm (3.24 in.) wide x90.2 mm (3.55 in.) deepTerminals• Controller input: Compression,accept #22 to 10(0.2 to 6 mm 2 ) AWG wire.
