DIN NANO 4CK

DIN RAIL 4-RELAY ELECTRONIC REGULATOR

    The DIN NANO 4CK is a 4 relays electronic regulator DIN rail designed to control refrigerated counters, display windows and static or ventilated refrigeration units with off-cycle or electrical defrosting in real time (RTC). It is fitted with three analogue inputs for NTC temperature probes, one of which is configurable as a digital input, an additional digital input, four relays for the compressor control, fans, defrosting function and alarm and buzzer.
    As option the connection to an echo temperature repetition.

      Applications

      • Control of refrigerated counters, display windows and refrigeration units.

      • Control of two evaporators with two temperature probes of end defrost.

      Main characteristics
      • Can be configured for hot, cold or neutral zone applications.
      • Can be configured for managing day / night (automatic modification of the setpoint for energy saving) activated by time mode (real time clock) or by means of the digital input.
      • Can be configured to manage two evaporators with dual temperature sensor for defrost termination.
      • Relay managing compressor and fans of evaporator (2 non-configurable relays) and defrosting resistances, alarm, pump down start, room light and compressor output (2 configurable relays).
      • Defrosting activation in real-time, up to 6 starts in 24h.
      • Defrosting can be configured for off-cycle, heating element or cycle inversion and frequency and durationcan be set. End-of-defrosting can be based on time or temperature.
      • Key operated manual START/STOP defrosting.
      • Key operated ON/OFF.
      • Cold room light ON/OFF switch with key or by means of door switch (if defrost output is configured like cold room light).
      • A temperature repeater echo display is available as an option.
      • 3-figure LED display sign, decimal point and plant status icons.
      • Internal buzzer for acoustic signals.
      • PEGO programming philosophy guaranteeing immediate start-up.
      • RS485 serial connection with Modbus-RTU or Telenet protocol.
      • Power supply 230Vac.
      • HACCP function with memory and visualization of the last alarm.
