Eurotherm 2604 Temperature & Process Controller

The 2604 controller is a highly stable, 1/4 DIN plug-in temperature and process controller, designed for demanding industrial applications. It features a dual five-digit display and a two-line LCD, providing clear visualization of alarms, status information, and user-configurable messages.

Description

The 2604 combines high stability, accuracy, and advanced functionality in a single controller. It supports one, two, or three control loops and offers versatile control strategies, including PID, valve, ratio, cascade, and override control.

Additional highlights:

  • Setpoint programming with up to 50 programs (500 segments, 16 digital events, guaranteed soak, and holdback modes). Each program supports up to three setpoints.

  • High-speed communications with Modbus®, DeviceNet™, and Profibus®-DP (in “f” versions).

  • Versatile universal inputs (TC, RTD, DC) with Instant Accuracy™ for reliable measurements.

  • Direct connection to Zirconia probes, enabling precise carbon potential control in atmosphere-fired heat treatment applications.

  • Advanced control algorithms and gain scheduling for precise, linear control—even in highly non-linear processes—while auto-tuning simplifies setup.

  • Toolkit function blocks, including timers and totalizers, allow creation of customized user configurations and specialized machine control strategies.

  • Configurable either via the front panel or using iTools software.
