4-5 Redundant Safety Controller Display

Optional

The Redundant Safety Controller limits the process air temperature from exceeding specific temperatures in case of a catastrophic failure of the primary PLC process air temperature control system. The controller is a modular, self-contained unit removable from the mounting housing. All parameters are factory set and adjusted; normally, no field adjustment to the internal controls is necessary.
