N323TR NTC RS485 24V int. clock Temperature controller 3 relays
The N323TR is an advanced refrigeration controller specifically engineered for complex cooling applications requiring sophisticated defrost management and multi-zone control. Featuring an integrated real-time clock, it offers intelligent defrost scheduling with programmable cycles on weekly, daily, or workday-only bases, optimizing energy efficiency and preventing ice buildup. A key benefit is its dual NTC temperature sensor inputs, which simultaneously monitor both ambient air and evaporator coil temperatures, enabling precise differential control and optimal system performance. The controller provides three independent relay outputs for comprehensive system management—controlling the compressor, defrost heater, and evaporator fan independently. With built-in RS485 Modbus communication as standard, the N323TR enables seamless integration into building management systems for remote monitoring and control. The IP65 front panel ensures reliable operation in humid, demanding refrigeration environments, making it ideal for commercial refrigeration, cold rooms, and display cases.
