The Partlow range of 1161+, 1801+ and 1401+ have a programmable safety cut out with optional outputs for
annunciators and alarms. A latched relay cuts power to your process if safe values are exceeded. These units
must be reset before the process can continue. They have the improved Plus Series hardware and user interface
for optimal ease of use.
