535-PROF Wiring with Limit Control
Limit Control
Temperature applications where abnormally high or low temperature conditions
pose potential hazards for damage to equipment, product and operator. For such
applications, we recommend the use of an
FM-approved temperature limit
device
in conjunction with the process controller. This wiring example illustrates
a typical application using the 535-PROF Process Controller with a 353 Limit
Controller.
