Watlow 1/4 DIN Temperature Controllers

Watlow's EZ-Zone PM Temperature Controllers provide value (ownership cost plus enhancement) for accurate control of process heating systems. Made in the USA, Watlow controllers have all the options needed for great control and ease of use including process inputs and outputs, communications and UL, CSA, FM, RoHS and CE certifications. The two EZ buttons can be configured for a quick one touch programmed function, like switching to heat or cooling. The Watlow EZ-ZONE PM controller is easy to use and is ideal for PID controller, over/under limit controller or integrated controller needs. Watlow 1/4 DIN controllers are the standard 1/4 DIN size of 96 x 96 millimeters or 3.78 inches square.
