| 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 two analogue inputs for NTC temperature probes, one digital input, four relays for the compressor control, fans, defrosting function and alarm (the defrosting relay can be configured as light command and the alarm relay as AUX) and buzzer. As option the connection to an echo temperature repetition. |

Applications • Can be configured for hot or cold applications. • 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. |
