The ST-35C is for use with Scully 5-Wire Optic Sensors, Model SP-FU series.
It can monitor up to twelve of these sensors in a “series” signal path. If any one
of the connected sensors senses liquid, the ST-35C will respond to this “wet”
condition; output relay contact opens and red light turns on. Although its typical
application is monitoring of sensors mounted on multi-compartment vehicles,
it can also be used for high level detection in storage tanks (tank farms).
One relay output contact is provided, which opens if any sensor detects liquid.
ST-35C is also used with vehicles equipped with Scully’s IntelliCheck® series
or Load Anywhere® Overfill Prevention Monitors. It interfaces with 5-Wire optic
socket(s) on these vehicles. The Control Unit has an explosion proof enclosure
for mounting in locations that are classified as hazardous. For additional ground
proving options, the system works in conjunction with the Scully Groundhog
Self-Proving Earthing Verification System
ST-35 – Multi-Point Controller
