ENDA ET4430-230 is an industrial digital PID temperature controller designed for heaters, machinery, ovens, plastic processing equipment and temperature-controlled industrial processes.

The controller has a standard 48x48 mm panel format and a 2 x 4 digit LCD display, providing clear indication of both process and set temperature values.

Selectable sensor inputs include:

• PT100
• J thermocouple
• K thermocouple
• L thermocouple
• T thermocouple
• S thermocouple
• R thermocouple.

The controller supports selectable On-Off, P, PI, PD and PID control algorithms, together with an automatic Self-Tune function for PID parameter calculation.

A Soft-Start function is also available for applications where heating power should be applied progressively during startup.

Outputs

The ET4430 provides:

• 24V / 20mA SSR control output
• C/A2 relay: 250V AC, 8A resistive, NO+NC
• A1 relay: 250V AC, 8A resistive, NO

The C/A2 relay can be used for control or Alarm2, while A1 can operate as Alarm1 or PID cooling output. Heating and cooling control is selectable.
