Bosch 3 channel Ignition module BIM203

This module is an external ignition power stage capable of supplying up to four non-transistorized ignition coils. The IM input signal should be supplied by an ECU with ignition signal outputs in the range of 10 to 20 mA, e.g. MS 4 Sport. The IM unit combines the robustness of a high quality production part with good electrical performance to provide an ideal solution for adapting non-transistorized coils to an ECU without internal ignition driver stages.
