The Model PFS-2 Precision failsafe is a
convenient, digital switch adjustable unit
designed for easy and rapid setting of both high and low limits.
Standard temperature range is -99°C to +199°C, with high temp model having a range of -99°C to +299°C.
This is the perfect unit for environments where the
limits are changed often
or where supervisory personnel need to be able to visually check settings.
When the high or low limit set with the failsafe is exceeded, the main heating
and cooling power relay is disengaged by the failsafe and the controller is notified of the event.
