Description

 The Series 94 is a microprocessor-based control with single input, dual output. This controller is added to thermal applications to limit overtemperature conditions. The limit controller provides safety assurance against instances where a high temperature runaway condition could occur from a shorted input sensor or an output device that could fail in a closed position. A limit controller is recommended for any application where thermal runaway could affect operator safety, damage to capital equipment, large product scrap costs or a fire hazard.

Watlow's Series 94 is a 1/16 DIN temperature limit controller with a NEMA 4X (IP65) front panel (optional). This high performance Controller is ideal for applications such as furnace and ovens, environmental chambers, semiconductor, food processing or any where an over-temperature condition would cause damage to equipment, product, create a fire hazard or pose a risk to personnel. Since the NEMA 4X front panel can be hosed or wiped down without damage to the controller it is also excellent where equipment needs to be cleaned frequently. The compact size of the controller allows more flexibility in applications where sace is a problem
