The NI SCC-AO10 is a single-channel isolated analog output module for NI SCC carriers, delivering ±10 V output controlled by E/M Series DAQ device DAC outputs. Each module references to its own isolated ground, tolerating up to 300 V common-mode voltage between grounds. The module drives ±30 mA output current and includes short-circuit protection rated to 37 mA indefinitely. Cascading two SCC-AO10 units expands the output range to ±20 V, with a maximum of two modules per carrier.
