  The Sodium iodide Active Background Rejection Experiment-South (SABRE-South)
is a direct dark matter detector soon to be deployed in the Stawell gold mine,
in Victoria, Australia. Monitoring of external environmental and experimental
conditions, (temperature, barometric pressure, relative humidity, high voltage,
and seismic vibration) is vital to ensure the data quality of the SABRE search
for dark matter via direct detection. These parameters are generally
non-time-critical in the range of Hz to a few kHz and constitute a slow control
system. We present the design of a novel compact, industrial-grade, and
self-contained slow control system for SABRE-South. This system, featuring
innovative hardware and software architecture based on National instruments
compact RIO (NI-cRIO) and LabVIEW can be scaled up at low-cost and is capable
of implementing the functionalities available in high-end SCADA systems while
maintaining the flexibility to integrate custom software code (i.e. C++,
PYTHON) for bespoke interfacing needs.
