The FX12-Knock is analog amplifier for vibration sensors. It will amplify small signals from piezo and other low level sensors for reading by a 0-10V input.
If you use the analog output version, it can be run to a FX350 or other FX controller and drive all the logic you’d need. The SSR (solid state relay) version could open a maglock when a certain pressure is reached, but no further logic, latching, etc.
This kit includes a knock sensor, pre-wired and ready to go right away.
Works with the BAC V - simply connect, configure, and knock another puzzle off your to-do list!
