The CSNK plugs into an IOX16 and provides 16 high voltage/current outputs using the ULN2803 chip. Loads of up to 60 Volts and 0.5A may handled (but not all 16 at once!). Internal clamp diodes are provided for inductive loads (see application note). Outputs are spaced at 0.156" so traditional CMRI style Molex adapters may be used, but screw terminals are available. CSNK is ideal for situations where you need to drive high current devices (incandescent lamps) and inductive loads. CSNK is handy for compatibility with existing systems using 12V power for signals.
