## Questions & Answers

**Q: So on "low" the relay triggers when the signal voltage falls below 12v? and "hi" when the signal rises above 12v? can you tune the trigger voltage?thx**
A: If you set it to "High" then the relay trips when there is + 12V on INT1 or INT 2. (+12 as in the positive side of the power source)

If you set to low, it will trip when their is -12v (technically 0 volts) on INT 1 or INT2 (-12 as in the negative side of the power source)

**Q: These are locking in the triggered position (Red light on), even with no trigger voltage. Any ideas, did I get bad ones?**
A: When you say no trigger voltage, do you mean that no wires connected? If so then you may have gotten a bad set. Otherwise, check the jumper pins next to the trigger input. See if it set to low.

**Q: What is the minimum to maximum voltage for both the low and high?**
A: Minimum voltage that will trigger high:  2.5V
Maximum voltage that will trigger low:  (Vsupply- 2.5V)

Measured this with Vsupply values of 12.2V and 13.6V. 
Used UNI-T UT61E multimeter for voltage measurements.

**Q: are these latching relays?**
A: No.  They have normally open and normally closed contact points and will flip to the normally closed position when the trigger stops.
