## Questions & Answers

**Q: Please verify:  contacts are 20amp, 120v and 'coil' voltage can be anything from 24vac/dc to 120vac?**
A: Yes to both questions. Enclosed Power Relay 20Amp SPDT. Coil voltage input is 24VAC/DC ; 120VAC ; 50-60 Hz

**Q: Can a 24 volt thermostat connection be used with this to turn on a 120 volt circulator pump?**
A: I am using the unit to power a duct booster fan, (120 V-1/4hp)from my 24v  out put terminal on my HVAC circuitboard powering the relay, so you should be OK.

**Q: What are the detentions of this relay?**
A: did you mean the dimensions if so its 60mmx82mmx47mm tall

**Q: I have two food warmers 120v @ 12amp that can not be on at the same time. Can I use this to allow only one warmer at a time?**
A: The connection is a single switch (SPDT, means Single pole double throw, and that means on or off)
If you connect one warmer it will turn on only that one. If you connect both to the relay it will overload it...it's a 20 amp device and 12 + 12 is 24, overload.

If you want to get creative you can connect a manual switch that connects to one warmer or the other then connect this relay to that device. Then, depending on which way the manual switch is, that warmer will be controlled, move the manual switch the other way and it will operate the other warmer.
