The Murphy 518APH-12 Tattletale is a heavy-duty safety relay for engines and equipment.
It's designed to monitor a closed loop of switches or contacts—if any one opens (or a Swichgage closes), it trips and breaks the circuit.
That makes it ideal for protecting diesel engines, generators, or industrial setups where you need to shut things down fast if something goes wrong.
This model runs on 12V, has a manual reset, and comes with a 14 amp fuse.
The output contacts are NCH and NOH, rated for 10 amps at 24V.
It's built tough for harsh environments and is commonly used in marine, ag, and power gen applications.
If you're wiring up a safety shutdown system, this little unit is reliable, straightforward, and does exactly what it should.
Keep your equipment safe and your mind at ease.
