The IGN4 Ignition Module - 4 Channel is a high current ignition coil driver for use with most inductive ignition coils.
This device does not incorporate dwell control, current limiting or current sensing, so should only be used in systems which offer precise dwell control using multi-tooth crankshaft reference sensors.
