Thermostat EKC 302D (Modbus) with alarm relay 084B4164

The EKC 302D thermostat is a reliable and intuitive electronic controller, designed for a wide range of applications in refrigeration and air conditioning. The device stands out for its ease of configuration and programming, reducing the time required to start up the system. The ability to select predefined applications from the menu allows you to tailor the controller to the specific needs of the installation.

The EKC 302D controller has four relays that can be used to control various system components, such as the compressor (directly or via a relay), solenoid valve, defrosting, auxiliary heaters, fans, alarm or lighting. The use of "zero crossing" switching technology and increased relay capacity (up to 20A for the compressor) guarantee high reliability and long device life.

Additionally, the controller is equipped with Modbus data transmission function, enabling integration with monitoring and remote control systems. It meets HACCP requirements in control systems, which is particularly important in food storage applications. It allows you to select applications and coordinate defrost cycles, also in systems with data transmission.

The device works with three types of sensors: PT1000, PTC (1000 Ohm / 25°C) and NTC-M2020, providing flexibility in choosing the right solution for a given installation. The controller is powered from a 230V, 50Hz network. The protection class IP20 ensures safe use in standard environmental conditions. It also has digital inputs (2xDI) allowing connection of additional sensors or external signals.
