Watlow, St. Louis, MO, has introduced the EZ-ZONE™ ST integrated control loop that integrates temperature control, power control, safety shutdown, and power disconnect in a single package. The system features a PID temperature controller already connected to a high-amperage solid-state relay with the option of adding a properly sized heat sink, current measurement, an over/under temperature limit, a definite purpose mechanical contactor, and digital communications. A remote user interface also can be added. The control loop is modular and scaleable, allowing users to choose only the components they need. The system can be stacked into multiple configurations, and features back-panel or DIN rail mounting. Other features are a touch-safe package and ±0.1 percent temperature accuracy. The system can be used in temperature control applications in plastics processing, packaging, semiconductor processing, analytical instrumentation, and general equipment.
