Product Description


The 2404 Eurotherm controller is a versatile, high stability temperature or process loop controller, with auto tuning in a 1/4 Din size.   It comes with a standard 8 segment setpoint programmer.  The hardware construction houses two primary outputs and a single alarm.  Output 1 is a Logic output for switching solid state power controls.  Output 2 is a Relay for switching cooling or auxiliary devices.  Ouput 4 is a fixed form C relay available as relay or program event.  We also provide at no extra charge an extra Relay module should you prefer to replace the Logic output in output 1.   Extra or replacement plug in modules for this controller are available on this website here

The 2404 is fully configurable on-site.

The programmer can have up to 8 programmable outputs which can be set in each segment to trigger external events. The two digital inputs can be used to run, hold and reset the program.

An advanced PID control algorithm gives stable ‘Straight-line’ control of the process. A one-shot tuner is provided to set up the initial PID values and to calculate the overshoot inhibition parameters.   Dedicated cooling algorithms ensure optimum control of fan, water and oil cooled systems.

A universal input circuit with an advanced analogue to digital convertor samples the input at 9Hz and continuously corrects it for drift. This gives high stability and rapid response to process changes. High noise immunity is achieved by rejection of 50/60Hz pick-up and other sources of noise. Sensor diagnostics are also provided. The input will accept all standard thermocouples, the Pt100 resistance thermometer and linear millivolts, milliamps or DC volts.
Input filtering from OFF to 999.9 seconds is included.

Customised operation
A custom LED display provides a bright, clear display of the process value and setpoint.  Tactile push buttons ensure positive operation. Access to other parameters is simple and easy to understand and can be customised to present only those parameters that need to be viewed or adjusted. All other parameters are locked away under password protection.

A front panel auto/manual button is provided.

Up to four process alarms can be combined onto a single output. They can be full scale high or low, deviation from setpoint, rate of change or load failure alarms. Alarm messages are flashed on the main display. Alarms can be configured as latching or non-latching and also as ‘blocking’ type alarms which means that they will become active only after they have first entered a safe state.

Digital Communications
RS485 modus and RS232 are available as optional plug in modules and can be purchased on this website here .  These are excellent methods of remote communication and cloning of new and replacement instruments through the Eurotherm Itools program When purchased through our website, each controller comes preconfigured for heat cool and J thermcouple input.
