Watlow EZ-ZONE® ST Integrated Control Loop Makes

Solving the Thermal  Requirements of Your System Easy

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, digital communications and a remote user

interface in one complete and professionally engineered

product.

Because the 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.

This integrated controller also includes 200KA short circuit

current rating (SCCR) tested up to 480VAC to minimize

damage in the event of a short circuit when used with

required fusing.

The options that you need…

A single driver module can support up to four power modules – and hence

four independent control loops.  Power modules are available in current ratings

covering a range from 100A to 630A.  The driver module itself supports options

boards to give you additional flexibility in your solution:

• Communications – RS485 Modbus RTU, Profibus, DeviceNet®, Modbus TCP

network protocols, CCLink*, EtherNet IP* and ProfiNet*

Predictive Load Management (PLM) – A powerful feature to effectively manage

your power requirements across multiple machines to save on your energy costs.

Read more about PLM.

• Flexible I/O – The driver module supports standard I/O and up to three additional

I/O boards with analogue inputs, analogue outputs, digital I/O and relay outputs

• LTC – The Load Tap changer option for single phase unit applications only, allows

for managing multi-tap transformers, preventing both increased harmonics and the

reduction of power factor
