Pro-EC44 by Danaher

The Danaher Pro-EC44 is a high-performance thermal controller from the Thermal Controllers series, designed for demanding industrial automation environments. This controller features a crisp 160x80px monochrome LCD with red/green backlight for clear process visualization. Housed in a standardized 1/4 DIN form factor with overall dimensions of 96 x 96 x 117 mm, it seamlessly integrates into existing control panels. The Pro-EC44 supports a wide operating range, accepting 100-240V AC (50/60Hz) or 24-48V AC/DC power inputs and offers up to 9 configurable outputs for relay, SSR, triac, or analog control. The unit accommodates 1-2 universal inputs compatible with thermocouples, RTDs, and DC mA/mV sensors, ensuring flexible temperature sensing options. With a front panel protection rating of IP66, the device withstands dust and water exposure in challenging process environments.

Performance is optimized through a rapid scan time of 100 ms and advanced single/dual PID control modes, including time, continuous, and three-point configurations, as well as basic on/off control. Users can define up to 64 profiles with 255 segments each for precise thermal profiling and process sequencing. The Pro-EC44 provides up to 9 digital inputs for event detection, and its communication interfaces include both RS485 (Modbus RTU) and Ethernet (Modbus TCP) for seamless network integration. Optional data recording and profiling capabilities allow process historians and trend analysis directly at the controller or via USB export. A front USB Interface facilitates parameter backups, firmware upgrades, and data transfers without disrupting field wiring or system uptime.

Built for robust operation, the Pro-EC44 includes seven alarm functions—absolute deviation, rate change, sensor break, memory error, and power failure detection—to safeguard critical processes and enhance safety. The durable front panel meets IP66 standards, resisting high-pressure washdowns common in food processing and pharmaceutical environments. Its universal inputs and extensive output flexibility enable integration with heating elements, chillers, and automated valve actuators across a broad range of applications. Backed by a 1-year warranty, the Pro-EC44 delivers consistent reliability, straightforward configuration, and scalable performance for OEM machinery, packaging lines, and laboratory temperature control systems.
