The EZ-ZONE® ST integrated solid state controller from Watlow® offers
a complete thermal system control solution in a single package.
Features include a PID temperature controller connected to a
high-amperage solid state relay with the option of adding a properly
sized heat sink, an over- and under-temperature limit, a power
shut-down contactor and digital communications in one complete and
professionally engineered product.
Because the solid state controller system is modular and scalable, a
user only pays for what is needed. Stacking the EZ-ZONE ST integrated
controller into multiple configurations enables flexibility to
standardize the product platform to solve a wide range of application
needs.
