RPM conditioner
The RPM conditioner is an adapter box to convert a “high level” RPM source, typically from an ignition coil, to a low level conditioned logic level output which can be connected to any of our data loggers and dashboard products.
The conditioner circuit is filtered and “optically isolated” which means that it is exceptionally robust to high level, capacitive discharge, noisy and ill-conditioned inputs which make it ideal for connecting any of our other hardware to problematic ignition systems.
The circuit should be connected as shown in the diagrams below:
