Attention!
Do not short circuit these signal lines.
Never connect any pins on the same plug or to any other plug on the MICROSPACE
MSB900/L. The +/-10 Volts will immediately destroy the MICROSPACE core logic. In this
case the warranty is void!
Do not overload the output; the maximum output of the current converters is 10mA.
