Amplifier for a logic level output

Amplifier module for a logic level output of a Decoder. Most ZIMO Decoders have such logic level outputs in addition to the normal function outputs, which are switched between 0 V (for OFF and 5V (for a) and need not be charged, but need an external amplifier. Mostly logic level outputs are an alternative use of the SUSI connections (Clock and Data), and are activated by CV # 124, bit 7 = 1. The output of the M4000Z supplies up to 0.5 A.
