E5C4 Digital Temperature Controller 0-399°C K Type/PT100 220V

Q: What sensor types are compatible with the E5C4 temperature controller?

The E5C4 thermostat supports both K Type thermocouples and PT100 RTD sensors. K Type sensors are commonly used for higher-temperature industrial applications, while PT100 RTDs offer slightly higher precision at lower temperature ranges. Choose the model variant that matches your existing sensor infrastructure.

Q: What is the maximum temperature range this controller can handle?

The E5C4 model covers a measurement and control range of 0–399°C. The E5C2 variant extends this range up to 0–999°C. Both models feature the same dial-code adjustment method and LCD digital display, making them easy to configure for your specific process temperature requirements.

Q: How do I install the E5C4 thermostat into my panel?

The controller is designed for standard 45×45mm panel cutout mounting. Simply cut the appropriate opening in your enclosure, slide the unit in from the front, and secure it with the included socket base at the rear. The relay output connects directly to your heating or cooling element. No advanced tools are required for a standard installation.

Q: Is this controller suitable for home use or is it industrial only?

While the E5C4 is primarily designed for industrial and workshop applications — including food ovens, greenhouses, fermentation chambers, and plastic machinery — it can also be used in well-ventilated home workshop or hobbyist setups where a 220VAC power supply is available. Always ensure proper electrical safety precautions are followed during installation.
