The Watlow SERIES SD PID Temperature Controller is a microprocessor-based device designed for precise temperature regulation in various industrial applications. Available in 1/32, 1/16, 1/8, and 1/4 DIN panel mount sizes, it offers a universal input capable of accepting signals from thermocouples, RTDs, or process inputs, providing flexibility across different systems. The controller supports up to three outputs (two for the 1/32 DIN model), which can be configured for heating, cooling, or alarm functions. Standard features include dual four-digit displays for clear process monitoring, an IP65/NEMA 4X-rated front panel for protection against environmental factors, and compliance with UL®, C-UL®, CSA, CE, and NSF-2 certifications, ensuring adherence to international safety standards. Advanced functionalities such as TRU-TUNE+™ adaptive control algorithm enhance temperature stability, while options like EIA-485 Modbus® serial communications and infrared remote communication facilitate seamless integration and user-friendly operation. The SERIES SD also offers a ramping version with up to four profiles and 10 steps each, including ramp, soak, jump loop, link, and end steps, catering to complex thermal processes. Additionally, the Variable Burst Fire feature reduces wear on heaters, prolonging their lifespan and minimizing downtime. These attributes make the SERIES SD PID Temperature Controller a versatile and reliable solution for diverse temperature control needs.
